Product Information

For example, if you are using a film that is balanced for daylight in tungsten light setting (indoor), it may create yellow tones to your image. To counter this, use a blue 8oA filter. This will neutralise the yellow to give balanced colour.

Well, since spectral sensitivity curves are not linear and color negative films have to "cheat" the spectral response of the dye layers (thus the orange masking) my *guess* is (and it's just a guess) that a straight 85 IS providing the proper correction to the dye layers. There are two types of fluorescent filters available to photographers. The FLD filter is designed for daylight film. The FLB filter is produced for tungsten film. While both absorb light, it has been my experience that an extra half-stop of exposure is required beyond what the camera suggests.A purple lens filter is often used to help reduce glare and reflections in photographs. It can also be used for color correction in photos, as well as to help bring out certain colors in a photo. What Do Color Filters Do On A Camera? When the light is reflected, it creates flare in your image. Flare is represented in one of two ways–by circles of light in your image or by a loss of contrast in a section of the image. As mentioned above, the primary purpose of these filters is to protect the front element of the lens from damage. The two main filters in this category are the Sky (1A) and the Haze (UV) filters. Some companies will designate these filters differently. A lens filter is unlikely to reduce the sharpness of your photograph. However, if the material used to make the lens filter is cheap, it may reduce the contrast and overall image quality. A lens filter can also reduce the sharpness of a photograph if it is not properly placed on a lens. As a result, while lens filters do not reduce sharpness, they do provide a valuable tool for photography. Do Lens Filters Make A Difference? Then all this would become proprietary and we could make lots of money and spend days in Museums looking at wonderful works of Art and marvel at the fact that these guys had never heard of 85 filters but still managed to get it right.

That's not how I remembered it so I fished out Kodak H-1 (Selection and use of MP films, 1976), Eastman Films for the Cinematographer 1994 and some K 40. Here's the story they tell.

As a documentary guy usually working wide open in low light conditions, I have a tendency to use a #82 filter. You don't lose anywhere near as much light as with a #85, and it gives a better look than using nothing at all and correcting exclusively in printing. Each one increases your creativity, at a fraction of the cost you'd pay for either a mounted(ringed) filter or Cokin square alternative. The following is the first of three articles on using filters. Part One discusses the main categories of filters used in photography, essentially camera filters explained

A Nikon 85B filter is a filter used to correct the color balance of images taken under tungsten lighting. It is placed in front of the camera lens and allows only blue light to pass through to the sensor. This results in images that appear more natural, with accurate colors. According to most ‘before’ and ‘after’ filter shots used for comparison testing, the majority of lens filters have no negative impact on image quality. Some critics argue that if you put a layer of glass in front of your lens, it will make your vision blurry. Lens Filters: To Use Or Not To Use? What amazed me was that a Chocolate filter, which certainly looks very different then an 85 correction filter produced virtually the identical correction as an 85 filter!?I am impressed with the discussion on the use of 85 and 85-B filters. A little history lesson might be appropriate in light of the wave of post production and computer imaging currently riding the crest of popularity. I respooled a film once, because I wanted to shoot redscale after I read about it somewhere. A pretty lomo thing to do. After this I wondered why I just didn’t go straight to an orange filter – same effect without the fiddly respooling part.
