Common tasks Resizing an image “Straightening” an image Cropping an image Adjusting brightness and contrast Adding layers
Resolution Number of PIXELS per square inch Monitors display 72 pixels/sq inch Printers are much higher –300 pixels/sq inch File size differences in 1X1 in –Web 5,184 pixels –Print 90,000 pixels
Color Monitors display light directly –Term RGB (Red Green Blue) –Different monitors may display colors differently Printing images –Term CMYK (Cyan, Magenta, Yellow, blacK) –Colors will look different than on the screen
File Formats Use Photoshop to open and create different kinds of file formats

History Undo –Takes you back one step Step Backward –Takes you back one step at a time History Palette (displays steps) –Open under WINDOW Revert –Back to the last saved version SAVE OFTEN WITH DIFFERENT NAMES!
Practice Using Tools Create a new document
Let’s get creative! Select foreground and background colors Choose the paint brush Now the eraser Try the pencil
Open Willie.jpg Image, Image size Pixel width 200 Bicubic Sharper SAVE as smw.jpg Open Willie.jpg Image, Image size Constrain proportions OFF Image, Image size Pixel width 200 (UNDO) Pixel height 200 (UNDO) Let’s open a file to be edited
Use Filters for Special Effects! Open Willie Select a Filter Example: Artistic, Dry Brush Save file with different name williedb
Curves Go to the Toolbar, click on Image → Adjustments → Curves Adjustments Brightness & Contrast Go to the Toolbar, click on Image → Adjustments → Brightness/Contrast The following tools are used to alter photos in order to bring out details and balance intensity.
