 Applications of Reflection Reducing Films. -Reflection reducing films are used for three purposes: (1) to increase the light transmitted through glass and other surfaces; (2) to reduce scattered light arising from multiple reflections between the optical surfaces in instruments; (3) to reduce glare due to reflected light. They find their widest application in optical instruments containing a number of elements: 120 Camera films and projection lenses, binoculars, telescopes, microscopes, periscopes, and so on. Transmission is increased and scattered light decreased.
The parents usually will buy such pictures no matter how inferior they may be-which is the reason why standards of baby photography are so low. With nothing more than a box 120 Camera films and with the worst of drug store processing of films and prints, you could still make a few dollars snapping the neighbors' children.
Panchromatic films enable you to get beautiful black-and-white results with ordinary 120 Camera films equipment, and often without color filters. This does not mean that filters have no use in this work, but it does mean that in many cases a Filter is not needed. In others the use of a Filter adds just enough more color correction to give you tone brightnesses in the black-and-white print that are comparable to those registered by the eye. While these "pan" films are best for black-and-white flower pictures because of their sensitivity to all colors, good results can also be obtained with Kodak Verichrome Film and the proper filter, such as the Kodak Color Filter or the K2 Filter. For information on these, see the preceding chapter.
