3 8 Graphic File Formats  A computer can save and interpret graphic images in a variety of formats. Some of the most common are: GIF (Graphics Interchange Format) JPEG (Joint Photographic Experts Group) TIFF (Tagged Information File Format) BMP (bitmap) PSD (Photoshop Document) PNG (Portable Network Graphics)

4 Graphics Quality  Two factors that determine graphics quality are resolution and color depth. Resolution is the number of pixels per inch. Computer Monitors use 72dpi. Color depth refers to the number of distinct colors an image can contain. It can range from 2-bit (black and white) to 24-bit (16.7 million colors).

5 Dithering  Creates the illusion that an image has more colors than it really has

6 Resizing  Resizing is changing the height and width of the image Correct Original Incorrect

10 Rule of Thirds  Divide the photo into thirds both horizontally or vertically to achieve balance  Place points of interest at intersections or along the lines
