Hello William

Interesting to read your workflow. Very well laid out. One suggestion. 
You mention the difficulty in having the whole image area in focus. I 
might suggest adding the diffuse lighting if you can find the budget. 
Chances are the "aperture" in your DSLR is opening to a very low number 
f-stop to let as much ambient light in as possible, for the correct 
exposure. If you increase the exposure time, or add more light, you can 
stop "down" to a higher number f-stop. The higher the number, the better 
the depth of field and the more in focus everything will be in the 
picture. You might already know this, but if you have not tried this, it 
might be worth the time to experiment a bit.
