2. The basics

2.1. Resolution: pixels per inch

2.1.1. ("how many of the image’s pixels left to right and how many of the pixels top to bottom will print for every inch of paper")

2.2. Has everything to do with how your image will print

2.3. Has nothing to do with how your image looks on your computer screen

2.4. "MP" stands for "mega pixel"

2.4.1. "mega" = million

2.4.1.1. ex: "9MP" means the image to be taken will be made up of 9 million pixels

2.5. "MB" stands for "megabytes"

2.5.1. ("millions of bytes")

2.6. Images are resized for the web (Photoshop)

3. "Pixel Dimensions"
