Step 1: Launch Photoshop.
Step 2: Go to File > Import, then select your scanner. It should be listed there. Mine is the ScanGear CS 7.2.5.x, so I click that. The Photoshop scanning menu should pop up.
Step 3: I click on “Preview” (1) so that I can see how much of the page I want to scan (2). Then I adjust the bounding box (That funny looking dotted box) around my sketch so that I am not scanning lots of blank paper.
Step 4: Please note that I have it set to Color, and 300 DPI (3). The image needs to be at least 300 DPI if you want it to look good when you print it out later.
Step 5: If your sketch is too light you can go to Image > Adjust > Auto Levels or Image > Adjust > Levels and play with the sliders to get it looking the best. I rarely do this because I am usually just going to digitally ink over it and delete the sketch layer, but if you want just a nice sketch you will probably want to adjust the levels.
Next I will show you how I digitally ink over my sketches.
