I hope this is the right place for this -- it's not a drawing but it is a question about drawing techniques.
I'm interested in the workflow for blocking out basic colors, composition, etc. then progressively fleshing it out in great detail. I'm pretty new to digital painting and I'm sure layers are involved, but was curious how I go about it.
I'm assuming I create a new layer for each "stage" of fleshing out the painting. Should the new layer be transparent or a copy of the underlying layer? If transparent, then I'd have to re-paint everything (but in more detail) each time, right? Or do people just paint in greater detail in some areas and leave the underlying bits showing through?
I know it's a basic question, sorry...
Whether you're doing everything on one layer, multiple layers, or on a physical paper or canvas, it's a good general guideline to only do one color at a time. Do your base color first, then your darker colors, then your highlights. Or you can do your highlights first if you're working with certain mediums such as colored pencil (since it's harder to go over dark colors with light ones). Digitally, here's what my layers usually look like:
1) Linework
5) MISC (aesthetic details)
6) Highlight (lighter hue with LUMINOSITY or SCREEN Layer Setting on)
4) Textures
3) >Shadow (darker hue or same blue with MULTIPLY/DARKEN Layer Setting on)
2) Base Color (blue)
I have them numbered in the order of how I do them, but the way they're stacked is how they end up looking. If you're not using lines, one shade of your Base Color is what I would do first. Then I'd apply shadows, and then put anything else on that section before I do the final highlights.
In simpler terms, do one shade of color at a time and build or sculpt up from there. You don't necessarily need to mess with transparency (everything can be 100% opacity), but you can make your highlights or shadows slightly transparent depending on how intense you need them to be.
Again, this is just what I've learned and grown accustomed to doing, so you can always develop your own way.
