I use black and white filters, especially lately since I'm starting to understand exposure and printing much better.
Enter a bunch of filters that have collected dust over the years. I have orange, yellow, red, green, dark green, blue, ND, Polarizers, UV, even some special effect ones. These I all understand, the function of them, what I can achieve.
But there is one that is purple that I cannot figure out. I look through it, and if I view sunlight it looks intensely purple, like how yellow would look on negative film. Any idea what this is used for?
It's marked 58SL V&V.

Could it be Magenta? If so it is used in colour work to correct the green cast of fluorescent lighting.

I'll see if I can snap a digishot through it and post it here so you can see how it looks.

Does it have a clear spot in the middle? That ad sounds like the same thing. V&V filter. VIOLET VIGNETTE

Amazing what you find on Ebay

Further down is a V&V that's just violet.

V&V

Yeah, it's like the vignetting filter, but without the center hole. The color cast is identical to that one. What's strange is that the one that is labeled same as mine has a much more blue tone than the violet mine it, but that could be color correction and the difference between various screens.

Still wonder what it does for b&w photography. I think I'll have to try a color chart in sunshine.

Thanks guys,

As close as you'll get to 'ordinary' (non-dye-sensitized) film.

Thanks Roger for the info.
I'm tempted to try it out now...

Some of the oddly colored filters were used with a polarizer and changed colors as the polarizer was rotated.
Special effects with color film, especially if you liked Burple.
Often seen with mysterious markings like "y-r" or "b-y" that told the color combination available.
