PHOTOSHOP
-Selection Marquees (shape): aka Selection tools
-rectangular, polygonal/magnetic
-magnetic wand (tonality rather than area, goes with tolerance, great for a
white background).
16 distinguishes different types of white, mad picky
Tolerance: how selective it’s going to be
-Unsharp Mask **Duplicate layer before sharpening**
Filter. Sharpen. Unsharpen mask. (gives most control!)
-Color balance: shift magenta-> green. Get rid of magenta cast.
MANIPULATES COLOR
-Hue & Saturation: manipulates color, colorizes, changes from black&white to
color. Colorize box. RGB mode. Black & white. Colonize. Can change picture
to any color.
-Auto Color: automatic color balance
-Auto levels and/or curves: automatically creates levels.
-Adjustment layers-Levels
Contrasts control feature
-histogram: data in shadows & highlights, gives us a real look in our pictures
in terms of contrast and tonal info. Black & white should be at the end of the
histogram. Black on left. White on right.
-curves: changes color, very difficult to use, can help change color

Document Summary
Magnetic wand (tonality rather than area, goes with tolerance, great for a white background). 16 distinguishes different types of white, mad picky. Hue & saturation: manipulates color, colorizes, changes from black&white to color. Histogram: data in shadows & highlights, gives us a real look in our pictures in terms of contrast and tonal info. Black & white should be at the end of the histogram. Curves: changes color, very difficult to use, can help change color. Transform: using the shift key to prevent distortion, hold proportion of the image. Command apple x keyboard command: switches background and foreground. How to make a contact sheet & what it is used for: file. Feathering: (1. 5 pixels is suggested)-blurring objects so it blends with the picture. Flattening image before printing reduces the memories file and the printing time. Check your image size and resolution before you print. Set your paper type and print quality (when possible)
