....produced this chunk of East Indian Rosewood that I purchased in 1992. This was about the nastiest wood I have turned in years, so hard that the chips come off as tiny purple granules that are now everywhere! This wood is not as oily as Cocobolo, so the finish is rubbed in lacquer and Renaissance wax buff. 8"Wx4"H
>>>that light bounced from the blue backgrounds would tint the wood blue!
It is a little-known fackt that north of 36.5 degrees latitude the extractives in very old East Indian Rosewood combine with a thin coating of clear lacquer to absorb wavelengths under 500 nm and re-emit them as white light, somewhat analogous to the opposite of multicoating a glass lens.
....mineral salts in the lacquer has not proven to be effective at diminishing the blue reflectance of a light source bounce when subject wood is in proximity of said blue field! (;-D)
I keep several shades of grey mat board for darker and lighter objects. I put curved pieces in a 2x2 photo cube and light with a couple of photo CFLs and one small highlight lamp with a piece of tissue diffuser, Canon 70D these days. I can get a useful photo on occasion but it's nothing to write home about. Most of it is in the arrangement and the lighting, of course. I usually try 10 things before I get one I half-way like.
Some day I'd like to take the Jamie Donaldson course in animal and studio still life photography.
