A Tiffen 86C (Coarse Thread) FL-D Filter is used when you wish to correct for the greenish tone that appears when shooting daylight film under general purpose fluorescent lighting.  

NOTE: The FL series of filters alone does not always guarantee 100% correct color balance when shooting under fluorescent lighting. They are general purpose filters intended for moderate correction and will not, by themselves, necessarily provide perfect color rendition.

An FL-W filter is used to balance daylight film under warm white or white type fluorescent lamps. An FL-B filter is used to correct the color balance when shooting tungsten film under fluorescent lighting.

Fluorescent lamps burn at many different temperatures and often require more demanding filtration for exact results. For specific filtration and professional use, it is strongly recommended that a color temperature meter be employed along with Color Correction filters (i.e.CC30M) when shooting under fluorescent lighting. This is the only proven way to achieve exact color correction.

Related Questions and Answers

Q: 1. There's a lot of confusion about the "single perforated" note, and that's my question too. Is this perforated one edge or both?

A: The ORWO UN54 35mm Cine B&W Film (100' Daylight Spool) is triple perforated film.

Q: 2. Hello, why does this filter seems to take two slots space when placed in the back slot of the Cokin P holder ? Only the front slot seems to be available when I put this filter. For example, CP + ND10 is possible but not CP + GND + ND10.

A: I just put the CP in the backmost slot, therefore taking up the very thin slot at back and one regular slot in front of it. Then I slid in both the dark gray and light gray filters into the two slots in front of the CP without any problem.

Q: 3. I already have the Cokin P filter holder, so I ordered this filter to fit into it. I was expecting a glass plate filter like my neutral density filters. Instead this is round and is too large to fit into my holder. Did I order the wrong filter?

A: The flange of the round circular polarizer is designed to slide into first narrow slot next to the lens so that it can be rotated independently of the square filter when using spilt screen ND filters. If it is too large for that slot you may have the wrong holder. It is a little difficult to slide in place if the holder is mounted, by inserting prior to mounting the holder on the lens can help.

Q: 4. Is this 2 sheets or 1?

A: The, Negative Supply Sheet of 4x5 ANR Glass for 4x5 Sheet Film Holder is one sheet.

Q: 5. How many in a case?

A: Unfortunately, these are only sold singly and not in a case.

Q: 6. Does this have the feet? The pictures appear to show two different products. Will this work on any Lightbox?

A: According to the manufacturer, the Negative Supply 4 x 5 Film Holder with Acrylic Glass does not have feet. You should be able to use it on a flat light such as the Kaiser light. They state if you are using their products, they recommend the Negative Supply 4 x 5 Scanning Kit with Pro Mount MK2 and Two Sheets ANR Glass, B&H # NE45SKIT2ANR, as the 4x5 holder is attached directly to this product and will provide stability (as well as one of their light sources).

Q: 7. My Cokin P Series Holder accepts the Cokin P164 Circular Glass Filter, and I the 77m adapter ring fits as well. However, the filter does not turn easily and the adapter ring allows the holder to spin easily. What has anyone done to make these parts work as they should?

A: If the filter is truly hard to turn and you are still in 30 days from B&H, you should contact B&H Customer Service to see if you can exchange it. As far as dealing with the holder spinning, I would suggest trying spinning of the filter in the opposite direction, the direction use to tighten the 77mm adapter.

Q: 8. After figuring my exposure settings, do I need to add another stop for the filter?

A: Not if you're using your camera's light meter.

Q: 9. Hello, what holder do I need to buy that the filter will fit in it? Thank you

A: This is designed for the Cokin P filter holder. http://bhpho.to/1uFxRzB
