The Konica Minolta 62mm Color Conversion Filter Kit comes with two valuable filters used to balance film under daylight, artificial, tungsten or standard (household) incandescent lighting.
You've been given an assignment to do some slide copying on a copy stand. Unfortunately, you only have daylight film and you notice that the copy stand is loaded with 3400K photofloods. Not to worry! An 80B is a strong dark-blue filter that will balance your colors back to reasonable normality. This filter can also be used as a "conversion" filter for when you are shooting in a room with incandescent light (household light bulbs) and daylight film.
This filter allows you to "balance", i.e. bring back, correct color tone to your images. There is some loss of film speed that may require the use of a tripod but, at least, your photos will demonstrate the proper tonality they so richly deserve.
What do you do when you must take some photos outdoors and all you have left is tungsten film? Using tungsten film in daylight will produce a bluish cast in the photograph. The 85 series of filters will "bring back", i.e. color balance the tones in your images. These yellow filters are used to correct differences in color temperature between the recording medium (film/video) and the light source.
