3. Digital Image Basics Digital Images are made up of Pixels Pixels are small units of light that make up the image. Each range of light is given a number to represent a color. White = 0 Black = 255 All other colors fall in between this range When you edit a photo in Photoshop, most of the work you will do is pixel- level editing.

6. Digital Image Basics Quality and Size of Image Depends on the amount of pixels used to create the image Referred to as Resolution The amount of pixels per inch determines the resolution Example: 300 ppi means there are 300 pixels per square inch of picture

7. A tip to remember… No matter the size of picture file, a digital image will usually look good on a computer screen. A 1 megapixel camera will display pictures on a computer screen as big as 8 x 10 that look great. Megapixels really matter when you want to print your images. A 2 megapixel camera will make beautiful 4 x 6 prints, but really should not be printed any bigger.

11. Editing Pictures Editing/Compressing a digital image alters the amount of pixels in an image. Cropping an image reduces the amount of pixels. Depending on the amount of pixels cropped and the print size, you may or may not see a difference in the image. Enlarging an image requires the computer to add pixels where none existed. This will cause a pixelation or distortion in your image.

12. Enlarging a small file When you try to enlarge a small file, there isnt enough information so the computer tries to comepnsate. This leads to your image becoming pixelated
