Objective: Adobe Photoshop is the premier photo editing software tool available. Whether you are working on a webpage, Powerpoint presentation, or a document to be printed, Photoshop can be used to enhance your images. Participants will learn about image file types, cropping images, compositing (putting several images together), ghosting images (for use as webpage backgrounds), using layers, creating masks, applying filters, and formatting text with bevels and other effects.
The internet was originally created by U.S. Department of Defense researchers to exchange textual documents. Once someone discovered how to add graphics to the exchanged document, however, the internet really began to take off.
As HyperStudio author Roger Wagner has observed, we live in a mediacentric society that increasingly relies upon multimedia in its varied forms to both inform and entertain us. It is natural for people living within this media-saturated culture to want to create some of that media-- and Adobe PhotoShop is the perfect tool for that task.
With PhotoShop, you can:
PhotoShop is a program that is so rich, complex, and powerful, people literally spend most of the waking hours of their life using it, and are still always learning new tricks and techniques! Thankfully, however, the learning curve for PhotoShop is not steep, and users can create very appealing products with a short introduction to the concepts and tools of PhotoShop. That is one of the primary goals of this workshop!
To help spark your own creativity, I have provided documentation of how I created the images used in this online curriculum in the last section, "Graphics Techniques." Every image in this curriculum that is not a "screenshot" is clickable to the provided documentation.
Here are a few quotations on creativity to reflect on (source1 and source2):
PhotoShop is expensive software if you purchase it commercially, but educators can receive a sizable discount. Suggested retail price in Spring 2001 for the full version of PhotoShop was $609, upgrade price was $199. Educators could buy the full version for $279.99, or upgrade for $199. Details about the $99 PhotoShop Elements are available below. Order at a local educational software reseller or by calling 1-888-724-4508 (6 am - 8 pm Pacific, M-F).
Updated information about the latest release of PhotoShop is available on Adobe's website. You can download a "tryout version" of PhotoShop from the Adobe website as well: but a fast internet connection is recommended as the file size is very large! (Over 40 MB)
** 128 MB of RAM required to run Photoshop and ImageReady concurrently
When creating digital graphics, it is often helpful to capture parts of your computer screen. Techniques and shareware utilities for capturing screenshots are detailed in my Multimedia Madness workshop.
A less expensive version of PhotoShop is available, called PhotoShop Elements. Unlike the previously released PhotoShop LE and PhotoDeluxe (which were both rather sparse in features compared to PhotoShop), Elements is a robust program that can meet the needs of most computer users. Because it does not support CMYK color separations, commecial printshops will have to use the full version of PhotoShop, but 'the rest of us' could get by quite easily with Elements for just $99. Read more and download a demo on:
Elements includes some cool features NOT included in the current full-blown version of PhotoShop until version 7, like creating a simple photo-gallery webpage without typing any HTML, and also a useful file browser. If you do want to create a photo-gallery without Elements, the freeware PhotoPage sofware is excellent for Macintosh, or Catalog Wizard for Windows computers.
Software alternatives to PhotoShop include:
More information about putting images online is described in my article, "Digital Photos Online." Other good programs for creating photo-gallery webpages with images (great for digital camera photos) include:
From the WINDOW menu, make sure LAYERS and NAVIGATOR have checkmarks beside them. These are floating palettes that are in the bottom right and upper right corners of the screen by default.
These basic techniques will help you view and navigate around within an image in PhotoShop:
Other PhotoShop Palettes can be viewed or hidden from the WINDOW menu at the top of the screen.

Composing Your Images (by Mark U.)
One thing we need to do whether it's taking the photograph or creating one in Photoshop is to make sure we compose it right. This section will introduce you to the rule known as "The Rule of Thirds".
Okay, so what exactly is this rule of thirds? Simply put, you place an imaginary
grid over your images that divides your image into equal thirds horizontally
and vertically - which in turn gives you striking composition. (Take a look
at this picture on the right to see a typical image set up with a grid.)
The idea is, like on this picture, you don't place the horizon in the middle of the middle square. By taking the photograph with the bridge just over the top of the first middle square you are not detracting from the main subject (the bridge and river) by placing far too much sky in the image. However, if it were the sky you wanted to mainly focus on, you would possibly place the bridge at the near bottom of the middle square, or into the next square below.
Sound confusing? Try it yourself... look through the viewfinder of your camera, pick a subject and then place an imaginary grid over the image, (some digital cameras offer the chance to place an actual grid on their LCD screen). If you are using a digital camera, take a few shots of the subject, but move the camera around. Take one with the subject dead centre, and take some more using the rule of thirds.
Although this is a rule to be followed when taking your photographs, like all rules, it can be broken. For example, what about a close up shot of a flower? With the image opposite, the rule of third has been broken, however, the centre of the flower is in fact in the centre anyway.
Hopefully, this will have given you some idea on how to compose images you create and your photographs.
When creating your images from scratch, place a grid on a separate layer to help you with the guides.
After opening PhotoShop, set your preferences for images. I recommend doing this by:
Next, choose FILE - NEW. Specify the height and width of the new image. For your first image make it 450 pixels wide and 300 pixels high:
As a rule of thumb for webpage images, use a maximum width of 450 pixels. If you make images too wide, they will not completely be displayed if a web visitor's screen size is set to 640 x 480, or their browser window is small.
Image Mode is important, because it determines the type of FILE FORMAT you can save an image as. In general, stick with RGB color unless you are saving a file as a GIF (discussed below):
INDEXED COLOR is used for GIF images. This format is limited to a 256 color palette. The fewer the colors contained in the palette, the smaller the file size.
CMYK and other image modes are used extensively by commercial print shops, who must have precise "color separations" for their printers.
More on resolution image settings from Mark U:
Definition: Resolution is a measurement of the output quality of an image, usually in terms of samples, pixels, dots, or lines per inch. The terminology varies according to the intended output device. PPI (pixels per inch) refers to screen resolution, DPI (dots per inch) refers to print resolution.
Often images are referred to as high resolution (hi-res) or low resolution (low-res). High resolution would be an image intended for print, generally having 300 pixels per inch or more. Low resolution refers to images only intended for screen display, generally having 100 pixels per inch or less.
Scanner and digital camera manufacturers often refer to two different types of resolution when listing product specs: optical resolution and interpolated, or digital, resolution. The optical resolution is the true measurement of resolution that the output device can capture. Interpolated, or digital, resolution is acquired artificially.
Resolution is also known as: rez, res, dpi, ppi, hi-res, lo-res, low-res
Contrary to what you might think, ppi is not the same as dpi. Almost everyone these days has a inkjet printer so let's think about your inkjet printer for a moment. How many colors of ink are in your inkjet printer? Most of them have at least four and possibly six ink colors. When your printer lays down ink, it lays it down in overlapping dots of these four or six colors. Images are made up of pixels (see definition below) and Photoshop defines resolution in pixels per inch. In a typical RGB image, a single pixel represents one color out of the millions of colors that can be reproduced on-screen.
(Pixel: a pixel is the smallest display element that makes up the images you see on a computer monitor or television. A typical image contains millions of pixels, which is why digital camera output is defined in megapixels (mega=millions). In bitmap-based images, the more pixels an image contains, the higher its resolution.)
So how can a printer with only six colors of ink reproduce millions of colors? Well, certainly not by printing a single dot for each pixel in your image! In reality, for each pixel in an image, your printer may lay down several dots of overlapping color that mix together to make up the color of that single pixel. All this is said to help you understand why you would use an image resolution setting of 150 ppi in Photoshop in order to output an image with a printed resolution of 300 dpi. It's simple; your printer needs to use more than one dot to represent the color of a single pixel.
To clear up another confusing matter, resolution (ppi or dpi) has no bearing at all for images that will be viewed on screen. The only thing that means anything for screen display is the pixel dimensions; that is, the number of pixels that make up the width and the number of pixels that make up the height of the image.
If you've been told that you need to use 72 or 96 ppi for the Web, it's only because that is approximately what a typical monitor can display. But, because we have the ability to adjust the pixel dimensions of our monitor, and because monitors come in varying sizes, an image with the same pixel dimensions is not always going to appear the same size on screen on every system and with every monitor.
A large variety of image file types exist that can be confusing. If you want to get confused, take a look at this exhaustive list compiled by the Center for Innovative Computer Applications. Whenever you save a file in PhotoShop, you can choose the FILE FORMAT to save in:
In this class we will keep things a bit more simple. We will primarily save our files in PHOTOSHOP format. This format has the benefit of retaining the different layers you create in the image (they stay separate, instead of being "flattened")
Two of the best known image formats (because they are widely used on the internet) are:
JPEG (Joint Photographic Experts Group) retains 24 bit color (millions of colors).
GIF (Graphics Interchange Format) developed by Compuserve.
To resolve problems with some graphics appearing differently on Macintosh and Windows computers (which share 216 of the 256 colors in the 8 bit color palette) download a Photoshop "web safe" color palette: www.homepage.co.uk/webcolour/
The standard operating system graphic file formats have been:
When saving a PhotoShop image as a JPG file, several options will be presented:
Select image quality based on the expected use of the file (internet images should be smaller) and desired quality.
SAVE FOR WEB OPTION:
This tutorial on "Basic Image Manipulation Using Photoshop" is excellent.
PhotoShop 7 includes support for web transparency, missing in previous versions. This is most useful to web designers making graphics with transparent backgrounds.
Additional information about images and their use in webpages is available in the ADVANCED IMAGE TECHNIQUES section of my INTERMEDIATE WEBPAGE WRITING workshop.
The PhotoShop toolbar contains a large array of selectable tools for image manipulation. The toolbar in PhotoShop 6.0 for Windows looks like this:
Many of these tools have multiple options, which can be selected by clicking on them and holding down the mouse.
Tools with other options have a small arrow in the lower left corner:
* Both of these graphics / diagrams were scanned from the Adobe PhotoShop 6.0 Quick Reference Card for Windows
One of the best features of PhotoShop is its ability to allow multiple undos. This means that, unlike most programs which allow you to just "undo" the last thing you did, PhotoShop will let you go back MANY steps.
Use the History palette () to "move back in time" and undo past actions.
After a file is closed, actions are not saved, however, so complete all undos before closing.
One of the best sources for graphics is the internet. Any image copied from a webpage can be inserted into PhotoShop easily.
Refer to the information below from my Intermediate Internet workshop for review of copy / paste skills.
All computers have a short term memory bank called the "clipboard." Unless you install special software, the clipboard will remember one thing at a time that you copy. This can be a bunch of text, an image file, or a sound file.
Multitasking: Using more than one software application at a
When we copy and paste text or multimedia elements, usually we need to multitask. This means that more than one application is open at the same time.
Information about saving internet images as separate files is also available.
The drawing and painting tools are located in the second part of the PhotoShop toolbar:
Whenever a tool is selected, like the Airbrush tool (), options for that tool are shown at the top of the screen and can be changed by clicking on each setting:
Note that some tools, like the Fill tool (Paint Bucket), are hidden by default behind another tool choice (in this case, the Gradient Tool):
Also note the differences between tools: the Paintbrush tool () located beside the Airbrush tool, and the Pen tool () located below the Path Component Selection Tool ():
Refer back to section on other tool options for more details on other tool choices.
Of all the drawing and painting tools, the pen is the most challenging to use.
This tutorial on the pen tool is excellent!
To practice, try this pen tool excercise: http://www.designsbymark.com/pstips/misc_pentool2.shtml
As a technique, create a new layer (as described next) for each different part of your image before you draw on it. This gives you more control and ability to undo past changes.
One of the most powerful features of PhotoShop its is ability to preserve different parts of an image on different "Layers."
How do Layers work? (by Mark U.)
Well, one way to think about it is this. You are making a sandwich for a quick snack; you place your butter on the bottom slice (Background). You then add a piece of ham (Layer 1), some cheese (Layer 2), and some tomatoes (Layer 3). Finally you put a piece of buttered bread on top (Layer 4). Apart from making you hungry, just think of layers in this way.
According to Adobe:
Layers provide a powerful way for you to organize and manage the various components of your image. For example, by placing an artwork element on a separate layer, you can easily edit and arrange the element without interfering with other parts of the image. To organize related groups of elements, you can nest several layers under a layer set. Layers also provide the basis for managing and defining advanced features such as Web animations and rollovers.
When working with an image, I usually keep the background layer empty (blank) and paste all the image components on different layers.
The Layer palette within PhotoShop displays different layers, and can be shown by choosing WINDOW - SHOW LAYERS.
The image below includes different layers, including a TEXT layer and background layers:
One of the most basic ways to edit an image is to CROP it: remove unwanted portions and focus the viewer's attention on a particular aspect or element.
Cropping a photo means cutting out parts of the photo by making it a smaller rectangle. This example of photos taken of Elian Gonzalez as he was rescued / taken by US officials in Miami shows cropping. The top photo includes a sign on the fence, while the second photo does not.
Aspect Ratio is the comparison of the width of an image to its height. You might have heard of aspect ratio of DVDs. According to the website DVD Dymystified:
Video can be stored on a DVD in 4:3 format (standard TV shape) or 16:9 (widescreen). The width-to-height ratio of standard televisions is 4 to 3; in other words, 1.33 times wider than high. New widescreen televisions, specifically those designed for HDTV, have a ratio of 16 to 9; that is, 1.78 times wider than high.
Aspect ratios are also important with digital images and photographs. If an image in Photoshop does not have the correct aspect ratio, when it is printed (by a service like Shutterfly.com) then part of the image will be cropped off. This is because of aspect ratio: the same reason a widescreen DVD played on a standard television only fills the middle part of the screen. The movie size is made smaller so it all fits on the screen without being cropped off. If a movie is NOT shown in widescreen format, parts of the movie edges have been cropped. That is what the message "This movie has been adjusted to fit your screen" means at the start of VHS movies.
These are common aspect ratios for film and print sizes:
|Ratios of common print sizes:||Ratios of film sizes|
|4x6 = 1.5
5x7 = 1.4
8x10 = 1.25
11x14 = 1.27
16x20 = 1.25
|35mm = 24x36mm = 1.5
4x5 (medium format) = 1.25
6x7 (medium format) = 1.17
Impact for PhotoShop Users: If you are going to print a digital image as a standard size photograph, make sure the image size has the correct aspect ratio. Aspect ratio is controlled by changing the image size (descripted in the section on Transformations)
Crop an image in PhotoShop:
After selecting the text tool (), text options are displayed at the top of the screen that can be changed as desired:
To add text to an image:
To add a fancy layer effect:
Layer styles can be used on other layer types also! (See the section on Fun Stuff for more layer effect tips)

Create a photo collage, or composite image, by creating or inserting different images within the same PhotoShop file.
This image was created by a 5th Grader at Rush Elementary during 2000-2001 and entered into a state digital graphics contest (where it placed in the top 3 for grades 3-5):
This image was actually created using PaintShop Pro rather than PhotoShop, but the techniques and concepts are the same:
To create a photo composite:
Curves, Levels, and Contrast/Brightness (intro by Mark U.)
Photographs scanned into the computer or taken with a digital camera are rarely exposed perfectly. Which of available methods in PhotoShop should you use to adjust the contrast and brightness of your images? The standard wisdom is that Curves are best, Levels are decent, and Contrast/Brightness is only for beginners. But this isn’t necessarily true.
In many cases, Contrast/Brightness is just fine. And, quite often, the precise control available in Curves leads to very unnatural looking images. The human eye is exquisitely sensitive to variations in lighting. If a part of an image is brighter, sharper, clearer than the implied lighting throughout the rest of the image requires it to be, we don’t trust, or believe in the accuracy of that image. We’re not talking about overcorrected, poorly done images. Instead, we’re talking about the ones that have been carefully manipulated by a Photoshop expert. You may not be able to put your finger on exactly what is out of place, but at a subconscious level, you can feel that it is wrong.
If a picture is intended for commercial use where the details in a product,
or a the face of a CEO are what is important, then manipulation may be useful.
However, if you are making art, or trying to create convincing illustrations,
keeping your images believable should be very important to you.
With close-up images, where the sources of light cannot be seen, a picture can be heavily manipulated, and remain convincing. However, when lighting clues such as shadows, reflective surfaces, windows, doors, the sky, or the sun are included, there is very little room for local tonal shifts. The eye needs to see a reason for extra brightness or clarity if one area looks different from the rest of the image.
Curves can make local changes that are not believable. It doesn’t have
to be used this way, but it usually is. Levels spread or compress the overall
tones of the image, while allowing you to position the endpoints in a way that
does not lose any image detail. This is believable because the changes are global.
Brightness/Contrast also makes global changes that are believable. The bad thing about Brightness/Contrast is that it does not allow you to position the endpoints of the tonal scale. Tonal detail that is almost white, or almost black can be shifted to be pure white or pure black by contrast or lightness moves made with this adjustment.
Some techniques for color correction include:
Adjust the CURVES
Adjust the LEVELS (the definition of pure white, pure black, and the point midway between these values)
If this result is not desirable, manually define the pure white and black values for your image by choosing LEVELS from this menu and:
Adjust Contrast, Brightness, and Color Balance
Use the Clone Stamp Tool to "Touch Up"
One of the things Photoshop is widely used for is color enhancement. We can achieve this using a combination of the Levels and Hue & Saturation commands.
Your image should now have colors that are more vibrant and stand out a lot more than the original image.
Additional resources on Photo Retouching are available:
PhotoShop can be used to take a normal photograph (like this close-up of my golden retriever, Bailey) and create a "ghosted" version that can be used as the background for a webpage or another document, with readable text on top of it.
This technique involves three basic steps:
To create a "ghosted" image:
The key to creating professional looking images with PhotoShop is usually being able to SELECT just the part of the image you want to do something to: apply an effect, cut out a background, etc. These tips may help.

Use a LAYER MASK
Masks can be created in PhotoShop to hide or reveal parts of an image. A Layer Mask is a special greyscale image attached to a layer, which determines how the two layers blend.
To create a layer mask:
If you want to learn more about Masks, try these tutorials:
Once you have made a selection in an image, different types of trainsformations are possible. These include changing the size (scale) of the selection, rotating it, or changing its shape in other ways (skewing or distorting). Selections can also be flipped vertically or horizontally.
To transform a selection:
To apply a transformation to an entire image, choose EDIT - SELECT ALL before choosing a transformation.
Images can also be resized by choosing IMAGE - IMAGE SIZE from the menu bar: . Increasing image size will result in a loss of resolution.
Make sure the units of measurement are set to pixels, and leave the Constrain Proportions checkbox checked, so that your image isn't squished horizontally or vertically when you resize. Change either the vertical or horizontal pixel measurement, and Photoshop will adjust the other measurement accordingly.
Choose to increase the CANVAS SIZE when you need more work area / space.
Layer Effects / Styles (by Mark U.)
Many of the well known PhotoShop techniques (like beveling and creating drop shadows) have now been made LAYER EFFECTS.
After making a selection (as described in the previous section), choose LAYER - LAYER EFFECTS as described in the section on using type.
Layer effects can be applied to any layer in an image. They cannot be applied to the image background layer, if there is one. Turn the background into a regular layer if you want to apply an effect or style to it. To do this, double-click the background and give it a name. Or, after double-clicking, you can simply click OK to accept Adobe’s default name of Layer 0.
If a layer already has effects or styles applied to it, and you want to add the new effects to those rather than replacing them, press the Shift key as you use any of the ways described below to add the additional effects or styles.
There are many ways to add effects or styles. The quickest is select the layer and then click one of the styles thumbnails in the Styles palette. This will instantly add that style to the selected layer. You can also double click the layer’s name to open the Layer Styles dialog box. All of the individual effects can be added or removed from here by checking, or unchecking items in the menu at the left side of that dialog box.
A style thumbnail can be dragged from the Styles palette onto the layer you wish it applied to in the Layers palette. A thumbnail can also be dragged onto the image. It will be applied to whichever layer contains the pixels where you drop the thumbnail.
Other methods of adding layer effects are—select the layer you want the effect to be applied to and then click the Layer Style button at the bottom of the Layers palette (shown at the top of this page) or choose Layer > Layer Style and pick the effect you want from the menu. Both of these methods will open the Layer Styles dialog box where you can customize the effect.
Layer styles already applied to one layer can be copied and applied to another
layer. There are two ways to do this. To copy and paste, select the layer which
has the style you want to copy. Then choose Layer > Layer Styles > Copy
Layer Style. To paste the effects onto one layer, choose Layer > Layer Style
> Paste Layer Style. To copy the effect onto multiple layers at once, link
them and then choose Layer > Layer Style > Paste Layer Style to Linked.
You can also copy effects by dragging from one layer to another. Drag either a single effect, or the Effects bar (which is shown at the top of the illustration at left) to copy multiple effects. If you like, you can drag an effect from the Layers palette onto the part of the image to which you want it applied. It will be added to that layer which contains the pixels you drop it onto.
Layer effects move and change with the layer. You don’t need to be worried that they will become out of alignment, or fall apart if you transform the layer. You can add or remove effects at any time. Their settings can be edited at any time. Double-clicking the layer, or one of the effects, will open the Layer Style dialog box where you can make any changes you like at any time.
Styles applied from the Styles palette can be removed by selecting the layer
which has the style applied and then clicking the No Style thumbnail. It’s
the very first one in the palette in the upper left corner. It’s a white
square with a red line drawn diagonally across it.
Remember that most of the layer effects work on the edges of the layer’s content. The Overlays, and Satin are exceptions.
Dodge and Burn (by Mark U.)
These are two very useful tools for image editing. They can be used either to increase or decrease local contrast, as well as for apparent sharpening of fine details.
Dodging and burning are techniques used by photographers during printing to
increase or decrease exposure to particular areas of the image.
The tools by this name in Photoshop have one big advantage over traditional burning and dodging techniques; they can be limited to shadows, midtones, or highlights. This means you can either increase or decrease the intensity of highlights or shadows.
Consider the fact that the Levels, Curves, and Brightness/Contrast commands work by brightening highlights, and darkening shadows throughout the image. Curves can be selectively applied to one level of tones, but the tones of that value throughout the image will be affected. With the Dodge or Burn tools, you can manipulate highlights, midtones, or shadows, only, and do it locally.
The Dodge tool is used for lightening tones, and the Burn tool is used for
making tones darker. Please note that neither of these tools is good for using
on evenly toned areas such as open sky, or untextured surfaces.
A few, very basic tips on using filters:
Available filters are listed in the FILTER menu. Filters are organized into categories. Additional (third party) filters can be added also:
To apply a filter:
Photoshop Actions (by Mark U.)
If you use Adobe Photoshop, but have never used Actions, you are missing a
large portion of what the program can do. Don't get me wrong, one can live without
actions, but once you use one, you find out how much more efficient and easier
they make graphics work.
Several action sets are included on your workshop CD.

This caution from the Adobe PhotoShop tutorial should be heeded:
Please remember that existing artwork or images that you may want to include in your project may be protected under copyright law. The unauthorized incorporation of such material into your new work could be a violation of the rights of the copyright owner. Please be sure to obtain any permission required from the copyright owner.
"Do I have to get permission to use this?" "Is this legal?" "If it doesn't have the copyright symbol on it, is it still copyrighted?" These are important questions, which unfortunately do not often have clear answers when it comes to using multimedia created by someone else in your own work. The most conservative guidelines are:
Do educators have to follow such conservative, stringent guidelines in order to remain in compliance with US copyright law? No. But if you don't, the answers to the above questions can be vague and harder to understand.
In the past, educators enjoyed additional rights when it comes to copyright and multimedia, thanks to EDUCATIONAL FAIR USE provisions of US copyright law. These rights were not unlimited, however. Restrictions existed for:
The Digital Millenium Copyright Act did away with "Educational Fair Use." Now, there are no "bright line rules' for determining "fair use" (like a certain percentage of the work is permissible.)
The following considerations should be used to determine "FAIR USE:"
1 - Purpose / Character / Nature of the Work
2 - Publication status
3 - Portion used
4 - Effect of use
Note that whether or not the use of another's materials is properly documented is immaterial to whether or not the use constitutes FAIR USE.

Proper documentation of sources is very important, and should be modeled by educators as well as taught to students. This is required by the Technology Application TEKS (TA-TEKS) in Texas, as well as by law.
For example, provisions of the Technology Applications TEKS for Grades 3-5 (§126.3.B.3.b) require that students:
model respect of intellectual property by not illegally copying software or another individual's electronic work.
Provisions of the Technology Applications TEKS for Grades 6-8 (§126.12.C.3.a) require that students:
discuss copyright laws/issues and model ethical acquisition and use of digital information, citing sources using established methods
