1 Digital Image Editing Presented by John Hohn

2 File Formats JPEG – Joint Photographic Experts Group PNP – Portable Network Graphics GIF – Graphic Interchange Format BMP – Bitmap TIFF – Tag Image File Format

3 Image Size and Quality Pixels – unit of measurement that creates a picture Resolution – The size of a digital image measured in pixels DPI – Dots Per Inch

4 Printing Pictures from your computer at 180 DPI 4" x 6" = 720 x 1080 = 0.78 MegaPixel 5" x 7" = 900 x 1260 = 1.13 MegaPixel 8" x 10" = 1440 x 1800 = 2.6 MegaPixel 11" x 17" = 1980 x 3060 = 6.0 MegaPixel 20" x 30" = 3600 x 5400 = 19.4 MegaPixel
