Okay my fellow artists, you should now have 2 scans of the same picture in your editing window. Be sure to have
each picture as a seperate LAYER... cause coloring is all about the layers.
Change both layer modes to multiply. Save file in assuming you have the option "photoshop" format (remember, just like
in video games, saving is your best friend... and do it very, very often while you work too!).
The inked scan *or the lineart scan without the shading* must always be on the top layer above all the other layers but
the position of the shade scan is not really important although if you have a LOT of layers, placement of subsequent layers
may be important... but trust me, you will get the hang of it.
Now comes the fun part... for each section of your picture that is a specific color, you should make a seperate layer
for it in normal mode and name it appropriately... ie, hair layer or sky layer or blue layers, red layers, steel layers...
etc.
For my picture I had a sky layer, then a mountain layer, then a back ground tree layer then a foreground tree layer and
then the spaceship layer and then the backwash layer from the space ship.
The clean art template was on top and the shaded art template was on the bottom.
Of course there is another technique you can use... but we won't go into that right now.
