1. The term "ISO speed" is used to describe what?

2. If an image is too magenta - what color adjustment should be made in Photoshop to correct it?
Add green
With the Main at 45 degrees to one side and 45 degrees above subject - it is a classic angle for portraits. It seems natural and flattering and models the face into 3D form.
Aperture - focal length - and distance to the subject
The number of pixels per unit of length in a image

3. If an image is too yellow - what color adjustment should be made in Photoshop to correct it?
