I am using a film SLR camera (Nikon N6006), and the film that I have right now is daylight film (Kodak UltraMax).
If I understand correctly, using a blue filter will mitigate the color issues that occur when using daylight film indoors under artificial lighting (fluorescent and LED). An answer to a different question on this site says that the Tiffen 80 series is the blue filter that I need, which matches what I've read about this issue on other sites.
However, as mentioned in that post, Tiffen offers a few variations on the 80 filter. I'd like to buy one of those filters, but I'm having an bit of trouble figuring out which one I need. According to Wikipedia, there are four types of 80 filters: 80A, 80B, 80C, and 80D. I found the filters on Amazon and Tiffen's website but could not find useful information there. (Google was not much more help, either.)
I'm guessing that there is no single "correct" answer because there are probably a lot of variables that affect this choice: the Kelvin temperature of the light that I'll use to take pictures, the film, and (possibly?) the lens and camera that I'm using. So unless I'm guessing wrong and there is one filter to rule them all, how do I figure out which filter to use? Do I need to measure the indoor lighting that I have to find a Kelvin value to match to the filters? (And, if so, how do I do that?)
tl;dr: How do I figure out which type (or types) of the Tiffen 80 filter (80A-D) to buy to avoid yellow indoor pictures?
