Ok SRK this is a value tutorial. Value is the brightness and darkness of a color. This is probably the MOST important thing to look out for when starting out a painting.
Ok so where do we begin? Let's ask ourselves a question first. What's the darkest and what's the lightest part. So I start to break it down with something like this.
Darkest value - Chun Li's hair. No doubt. Second darkest? Her body suit. Easy right. Third? Her skin. Fourth hmm. it's a tough call between the yellow and the off white ribbons and waist band. Yellow it is. Don't let yellow fool you. it is darker than it actually seems. Look at the yellow box and see for yourself. Fifth and lightest value is the ribbon and waist band. Now that you have distinguished which values are lightest and darkest it's time to move on. Easy right? Well here is where it gets a bit tricky.
From experience I'd say that shadow side value stays closer to each other than light side value where light shines. Now I have made little square boxes that I have eye dropped from each section. Notice the dark side column is very close in VALUE. Squint your eye and see for yourself. I even greyscaled it so you can see the outcome. greyscaling really helps if you are unsure of your value system. Notice when greyscaled, the blue, the skin and the yellow all fuse together as a one value. Pretty cool eh. Now take a look at the light side column. They should also be very close in value, but not as close as the dark side column.
So that's it. I really hope this makes sense. I also want you to take this test with another character. I would like to see your outcome. Post it up when you are done. Seriously if you practice this everyday you'll find that your pictures have alot more weight and depth in them.
Lastly I do these tuts to help you guys out. I pass on info that has been passed onto me. Posting tuts does not make me better than you. Have fun!
