Some admire wood finish more than utility. My brother was an intense woodworker until he...
I bought RR holders that are efficiently matt black.
I ended up painting all of the interior surfaces of my 8x20 and 11x14 wooden ULF holders a matt black and life for me as a ULF photographer improved substantively. As the old saying goes, necessity is the mother of invention.
As a telescope maker, I can sure attest to the effect of matte black on reflection reduction and contrast enhancement! I'm in the beginning stages of making my own holders, and will definitely paint the surfaces that will be in the light path from the lens to the film.
On my Phillips 7x17 camera with Lotus film holder inserted the amount of cherry wood exposed when looking thru the lens opening is negligible.
Hey...isn't there some product which has become available recently - a super absorptive black paint and/or cloth, or flocking material...which also happens to be (unfortunately) very expensive?
As Steve points out, the amount of film holder opening actually exposed is very small...but not always "negligible." But as the actual exposed area is so small, would this not represent a very cost-effective opportunity to make use of this new "ultra black" product? Richard?
