Screen Shots On the Mac

Use the keyboard combination Command-Shift-3 to take a picture of the entire screen that will be copied to the Mac hard drive.

To isolate a smaller, rectangular section, use the combination Command-shift-4, and then drag a square with your mouse to the proportions you need, and you will hear a picture being taken which will likewise be copied to your hard drive.

Macs save screen shots as PICT files, and will not open in Photoshop if you simply double-click on the file. In order to open the image, you must:

1. Open Photoshop
2. Go to File | Open
3. Choose the PICT File type from the pull down menu

Screen Shots On the PC

Select Alt-Print Screen to take a picture of the active window and copy it to the Clipboard.

Then just paste (Control-V) it into whatever application you are using.

There are also a number of more sophisticated screen shot utilities available as freeware or shareware on the web. These allow you to view and edit your screenshots, and have other helpful features.

Scanning

Scanning in the CWRL is a very simple process. All classrooms are now equiped with new Epson Perfection 1660 Photo scanners; Parlin 6 has two -- one for Mac users and one for PC users. The scanners are not hooked up to the network. To determine which computer the scanner is hooked up to, simply follow the USB cable out of the back of the scanner to the computer.

The scanners have one-touch features, which provide you with the ability to place the document you want scanned into the scanning bay, and press one of the four buttons on the front of the scanner: scan, print, email, publish on web. The large button on the left, will scan the document onto the computer so you can manipulate it.

Because of the network, however, you will most likely want to scan documents directly into Photoshop 7, which can be found in All Applications folders on both the Macs and MCs.

When placing your document on the scanner, be sure the document is face down and aligned with the top right, as shown below:

Scanning an image into Photoshop 7

1. Open Photoshop 7.
2. Go to File | Import | EPSON TWAIN 5...
3. 
4. The following window will then pop up on your screen, asking you if you want to scan in Full Auto mode or in Manual Mode. Full auto mode is the fastest mode, as whatever you place in the scanner will be scanned in to the computer. If you want to select only a small portion of what you have placed in the scanner, then use Manual Mode. In Manual Mode you can preview your scan and make specific adjustments based on what you are scanning.
5. 
6. 4. If you select Full Auto Mode, you will see the following window, informing you that the computer is scanning an image.
7. 
8. If you decide to scan in Manual Mode, you will see the following window, which has selections for:
9. previewing the image before you scan it
10. adjusting the source size
11. adjusting the scale
12. adjusting the image type and other configuration settings
13. returning to full auto mode
14. 
15. After you have set all of your settings, press the Preview button. The following window will pop up, informing you that it is previewing the document and determining if it is an image or text file or both.
16. 
17. A pre-scanning window will then pop up on your sceen, and gradually the document you want scan will appear begind it. In this case, a CD was scanned in.
18. 
19. After the scanner is finsihed pre-scanning, you will have the ability to select the entire image or just a portion of it to scan in to your computer. To select both the whole image and just a portion, position your cursor over the image, click and hold on the mouse (left click when using a PC), and drag over the entire region you want scanned. You will see a dotted line around the area that will scan. When you are finished, press the Scan button. You will see the same scanning window shown in step 4.
20. 
21. When the computer is finished scanning your image, the image will appear in a window in Photoshop. Depending on your settings, the image may be quite large, like the one below. Notice that in this case even thought the image is large, it is being displayed at 50% of its actual size. In short, the image is actual twice as big as what you are seeing on your screen.
22. If you select the Zoom tool from the Tools menu, and click on the image, you'll see it grow to its actual size. (Note: If the image is larger than the window, expand the window to fit the image. The actual size of the image may be larger than can actually fit on your screen, which is one reason Photoshop displays the image at a percentage of its actual size.)
23. 
24. A very large image might be nice because you can see all the details quite well, but larger ../images have much larger file sizes. The larger your file size, the longer it takes to download on to computers. So, when making ../images for the Web, it is best to have smaller images with smaller files that download faster so viewers of your Web page won't have to wait a long time to see the image.
25. There are, however, techniques for making it seem like large images are downloading faster, one of which can be seen at: http://www.eyewire.com/tips/mini/lowsrc.html.
26. To change the size of your image, go to: File | Image Size.
27. 
28. The following window will pop up, providing you will the ability to change Width, Height, and Resultion of your image. Scanner often assume that you will be using the image for printing, which is why it sets the Resultion at 300. For Web use, however, ../images only need to be at 72. By changing the resolution, your image will become smaller. If you want your image to have the same general dimensions, but on a smaller scale, make sure the Constrain Properties check box is checked. With that button checked, when you change the Width, the Height will adjust automatically. Select OK when you are finished, and you will see your image change its size.
29. 
30. Before making any other changes to your image, make sure you save your image by going to: File | Save, or Save As, or Save for Web.
