Tutorial 1: preparing the Line-Art
Step 1:
Scan in the line-art you'll be coloring.
Step 2:
Make it easier to color in by brightening the whites and darkening the black by going to Highlight/Midtone/Shadow...
Step 3:
Set it to Linear Adjustment method with Auto Proof checked (that makes it so whatever changes you do in the box will show up on the picture you've scanned as if you've applied the things in the box). Decreasing Highlight makes the whites brighter, and increasing shadow makes the blacks darker.
Step 4:
Go to the Layer Palette and right click on the Background Layer, then click duplicate.
Step 5:
Make sure the layer called Background is highlighted, and go to Selections and Select All.
Step 6:
Make sure, over on the right side of the screen, that the back color is white.
Step 7:
Click either Edit-Clear, or push the Delete key on your keyboard (this makes the background empty/white).
Step 8:
Click the box next to the layer called Copy of Background that says Normal and change it to Multiply (that makes it so all the white values in the picture can be seen through, as if it was clear; multiply only works with gray scale images, if you use it on a color image it turns it grayscale).
Step 9:
Deselect what you have.
