The purpose of this lab is to become familiar with the workings and layout of Adobe Photoshop.
If you are already familiar with this application, you are encouraged to share information with your
classmates for the Photoshop activities (7, 8 and 9).
Follow the tutorial below to learn to use Photoshop.
If you want to use an image from the Web, go find one from whatever source you like (suggestion:
Yahoo’s picture gallery or use a search engine such as google.com to find pictures of your favorite
subject) and copy that image into the clipboard by right-clicking on the image and select copy from the
shortcut menu.
1. Open Adobe Photoshop.
2. If you don’t have an image, use one from the Photoshop samples by using File in the menu bar and
select Browse. Click on one of the pictures.
If you found your own image, use File in the menu bar, select New. Get your selected image by using
Edit in the menu bar, select Paste.
Now that you have a picture, you can begin to alter it. The following is a legend graphic with the names
of each of the tools in the toolbars labeled. You may want to refer to this while you work.
In order to make changes to your image, you must select part of the image. The Marquee tool is used to
select a part of the image.
The default marquee tool selects a rectangular region. If you look carefully at the marquee tool icon, you
will see a small arrow in the lower right corner of the icon. This icon means that there are other tools
“buried” under that icon. To access these tools, click on the icon and hold the mouse button until the
other tools appear, then drag your mouse to select the desired tool.
3. The Move tool, to the right of the marquee tool, allows you to move a selection. Select part of the
image using the marquee tool and then move it using the move tool.
The lasso tool, below the marquee tool, allows you to select a “pencil defined” area of an image. To
select an area, start drawing with the lasso around the edge of the part of the image you want selected and
release the mouse button when you get back to where you started.
The airbrush tool allows you to paint color on your picture like you are using a spray paint can. You can
adjust the airbrush pressure in the toolbar at the top of the screen. Pressures close to 0% spray very
lightly while pressures close to 100% spray heavily.
The foreground color is the large black square near the bottom of the toolbar. The white square behind it
is the background color. To change the color, simply click on the square and select the desired color.
4. Use the lasso tool to select part of your image. Change the foreground color of your image. Now
select the airbrush tool and set the pressure somewhere between 30 and 80%. Spray on the image
inside the area you selected using the lasso tool. Now spray outside that area.
Notice how the airbrush paints using the foreground color you selected. Also, notice that the airbrush
only paints inside the area you selected with the lasso tool.
The paintbrush allows you to paint on your image as if you were using a paintbrush. You can adjust the
size of the paintbrush by clicking on the graphic to the right of “Brush:” in the toolbar at the top of the
screen. You can change the size of many tools inside Photoshop, including the airbrush used above.
The magic wand allows you to select regions of the same or similar colors. The tolerance setting in the
toolbar at the top of the screen controls how many colors are selected. Select a tolerance close to 0 to
select only a few similar colors, or select a tolerance close to 255 to select most colors.
5. Select the magic wand tool and select a tolerance around 10. Now click on part of the image and see
what happens. Now select Deselect from the Select menu.
6. Set the magic wand tolerance around 30. Again, click somewhere on the image and see what
happens. Now, select the paintbrush and paint in part of the selected area.
7. Now, while the paintbrush is still selected, check the box titled Wet Edges in the toolbar and the top
of the screen and paint again.
The rubber stamp tool allows you to clone part of your image. To use the rubber stamp, hold down the
Alt key and click on part of the image. This will remember where you clicked. Release the Alt key and
click elsewhere; this will clone the part of the image that you previously clicked on. If you continue
moving the mouse without releasing, it will continue copying from an area designated by the +.
8. Select the rubber stamp tool and try it out to see what it does.
The blur tool blurs the part of the image you brush with it. If you click on the blur tool and hold the
mouse button down, you will see the sharpen and smudge tools. The sharpen tool sharpens the image,
and the smudge tool simulates the effect of rubbing your fingers across pastels.
To the right of the blur tool is the dodge tool. The dodge tool lightens the part of the image clicked on. If
you click the dodge tool and hold down the mouse button, you will reveal the burn and sponge tools.
The burn tool darkens part of the image and the sponge tool can saturate (make the color brighter) or
desaturate (take color away) the image, depending on the option selected in the toolbar at the top of the
screen.
9. Try out the at least three of the six tools mentioned above (blur, sharpen, smudge, dodge, burn and
sponge) on your image.
You can use different Filters (available from Filter in the menu bar) to create different effects on the
image. You can apply a filter to part of the image you have selected using one of the selection tools or to
the entire image.
10. Apply at least 3 different filters to all or parts of your image.
There are a number of other helpful tools in the toolbar. They include:
Crop:
This tool is used to cut out a part of an image. Draw a box around the part that you want to keep
and then click the check mark in the toolbar at the top of the screen.
Eraser:
Will erase the image to the currently selected background color.
Magnifying glass:
Use this tool to view the image closer or further away. Select the tool, click on the image to view
it closer, hold the Alt key and click to view it from further. You can also use the top menu bar for
this function: View > zoom in/zoom out.
Eyedropper:
Click on part of the image and the foreground color is changed to match the pixel you clicked on.
11. Try using the four tools mentioned above. The magnifying glass and eyedropper will not alter your
image. If you crop your image, make sure you UNDO the crop function by selecting Undo from Edit
in the menu bar.
12. Save the file as Act7_lab section number_last name.jpg (which is JPEG format).
13. Submit the file the same way as previous activities.
