Hey there Concept Art People!
I had been scoping out this thread and decided to crank out one of the older studies from the 2nd peer project of 2005 just before work!
This is the first time I actually picked up my tablet, that I have had for a year, but had not used, to do the study.
I used Adobe Photoshop 6.0 and I shaded my spheres focusing on the value concentrations. I first filled in 8 different values and then filled the breaks with values in between and used the smudge tool to get the desired effects. I then selected the least concentrated value for my light source (the top corner, right).
This was the result:
Here's the result, transformed into greyscale:
This was a lot of fun! I think I will do the more "up to date" projects that have been explained in this new peer 2 peer thread. Constructive criticism is greatly appreciated!
