I recently posted an article about Design Process. In that post I mentioned a computer technique called “screen capture”. This is a very helpful method to document in a visual picture anything that you are doing on the computer. I use this technique all the time to show examples of computer techniques, research samples from the web or quick photo captures where resolution is not a factor. On a Mac the technique is simple, here is what you do:

To capture the entire screen or monitor press command, shift 3. To capture a cropped part of the screen press command, shift 4 and you will get a cross hair cursor, then click and drag a box around the area of the screen you want to capture. When you release the mouse you will hear a camera shutter sound and the image will be saved to your desktop. The image will be saved as a PNG file that you can open in PhotoShop and place in most other desktop publishing software, i.e. Illustrator or InDesign. Since you are capturing your monitor screen the image will only be 72 ppi, usually not high enough resolution for print but good enough to document your process.
