I made this tutorial for a friend, but it is dedicated for everyone that don't know how to use the Magic Wand too.
I used Photoshop, Paint Tool SAI and Gimp as example; but this serves for illustrator, Painter, Flash... and many others programs. Is a basic tutorial, and I didn't entered in many details in each program.
When an area is selected, you can colorize, move, transform or delete the selection. Is very useful!
About the Multi Select Mode, Paint Tool SAI have it already selected, and haven't a way of deselect this mode.
Ah, and others tools that can help the Magic Wand: Lasso and Select/Deselect. The Lasso is present in most programs, and the Select/Deselect only Paint Tool SAI have it. These tool, too, select an area in the image, but otherwise. I won't make a tutorial about them; test in your program and see the results
If you draw, remember that you lines can't have loopholes, or the wand won't select the desired area.
Oh... and I use Photoshop and Gimp in Portuguese language.
(...and I'm sorry if I wrote something wrong x_x')
I have trouble using the selection tool for more then one layer. For example, for the first layer if I want to select just the hair then it will work just fine. However, when I create a new layer to select just the skin it ends up selecting everything?
The selection tool can only select the content on the layer. If you created a layer and it haven't nothing, the selection ends up selecting everything. To select the skin, as sample, you need to use the selection tool on the layer where is the skin
Like this is what I have. For the first layer I import a lineart for coloring. And I am able to select any part without any trouble. However, when I make a second layer so I can just select the eyes for example it ends up selecting everything. You said that I need to use the selection tool on the layer where the skin is but since the whole lineart is one one layer does that mean I can only use one layer for coloring?
The thing is I have seen people on YouTube who use many layers, each layer corresponding to a different part(say eyes, skin, hair etc) How do I go about doing that?
Do you use SAI? Try activating the "All Image" option when select the Wand. If you use one layer to different parts, create a group for each stage of the drawing (sketch, lineart, colors, effects, etc) and put the corresponding layers in these groups. After, select the group and use the wand as "working layer".
