I may use a good many lights..."but"...(I feel better already)...they are "triple-filtered"! One photo tent, inside of a larger photo tent and white photo-grade muslin cloth over each individual light. Angling the blade, just right, allows for proper reflection...in many cases. Of course, I have "my days" when it doesn't matter what in the hell I do...the shots just don't seem to work out well.
I agree with you about the overcast days. I took the photo below, outside, with no direct sunlight overhead..."&" a photo tent. This is the #3-5" that the Randall shop put "on-loan" for me to be able to complete a story I'm working on.
Best, Capt. Chris
PS: #3, in thuya burl...Tomahawks by RW Wilson. RW made all of the knives and tomahawks for the movie, "Jeremiah Johnson". I'm proud to own these two...CCS
