Week 3 - Photoshop Picture Manipulation

Preferences

The first thing to do when I open up photoshop is to check/set my preferences.

Resolution

Second, I need to verify modes (the standard mode for web images will be RGB). The three resolution modes are RGB for web images, CMYK is for printing and the gray scale for when color isn't necessary or you prefer black and white. For the web, the standard resolution for image size is 72 pixels per inch (ppi). Setup any image at 120 ppi and up for printing (300-400 ppi for color printing).

Raster vs. Vector Images
Raster images are made up of pixels. Raster images are resolution dependent (bitmap). The best application to compose raster images is Photoshop.

Vector images are made up of lines and points. The best application to compose vector images is Illustrator.
