Midplane bend of abs, gradual darker tone towards the downplane. Even though the edge between the downplane and midplane has the most concentration of dark, this is not very obvious since there is a smooth gradation, and the reflected light from below is only a faint value lighter than the edge. This organisation of light/shade takes years to learn.
When working with values it's important to understand a few things.
Because of the glowing effect it is necessary to constantly refine the values you'd be working with - you might do something that looks good, but then if you tone down the area next to it, everything changes. For the same reason don't worry so much about being messy in the beginning, you can leave thousands of messy lines as long as they are of light or moderate value, then when you start working darker you'd loose most of them anyway.
It may sound strange, but for some reason we would always judge the darkest tone we see on the paper as being very dark. This has something to do with the way that the eyes and the mind work.
Even 2B pencil doesn't go very dark and if you doubt this compare the darkest pencil tone with a slip of paper rendered totally dark with charcoal or black chalk or black ink. Then all of a sudden the pencils darkest tone becomes a dull grey!
You can do the same trick if you are not sure how dark you are working - simply take whatever drawingtool you be using and a small slip of paper, and then just put on as dark value as possible. Then you can always put this slip of paper next to your drawing and it becomes easier to judge.
Another thing to be aware of when working with pencil is the fact that graphite is light reflective. This means that the darker you make something, the more it will actually reflect light. Thus when working with very dark areas in a pencil drawing, if these areas get direct light they will actually glow up and create specular highlights!
For this reason looking at a pencil drawing in different light situations gives a totally different effect of depth.
Charcoal on the other hand does not reflect light and goes a lot darker than pencil. For this reason it's a prefered medium of many.
But the ease of pencil makes it best suited in the beginning - and for some people, like sculptors or architects who only care about form, it's just perfect!

For some reason our eye can see even more tones than the general greyscale will allow. We just have to understand that it is a very relative thing - judging tone.
Therefore when doing Bargue copies or other stuff with fine rendering, it's important to work from a colour copy instead of greyscale, as it contains more gradation. A lot of older printers simply cuts away a lot of the gradation.
It's also very important to understand our medium, both pencil/charcoal and the paper. I don't wanna go into that as Dorian has already made excellent Bargue tutorials.
All right, done with this study. I should figure out a proper way to light the chest area but that will have to wait. In general this is how it's worked out - you try this, you try that, and if it works - Way to go!!
Another consideration is what you want. This way of drawing is especially suited to sculptors who have to think in terms of 3d form - they can take many more conceptual freedoms with the rendering and the outlining of the forms.
I had to delete some of the reflected light, it didn't work very well.
H1D this is a fantastic and highly detailed thread that will serve a lot of fledgling studiers of human anatomy, therefore I've decided to sticky this thread in it's own independent sticky until further notice.
Thanks for making such a great tutorial from your own hard work in school. Keep updating this please!
thanks a lot for sharing this, it's a great tutorial.
Don' t be afraid to cover things already covered by other members (dorian) you explanations could complete or fill a missing point. And many times, many members may have missed the dorian tutorial even if they always browse CA.
It would be fantastic to post all the things you will do in your school/atelier like dorian did. We would have the russian method of teaching.
and by thr way your studies are great !
