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.

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.
