MBA One of the oft neglected pieces of equipment that should be in every investigators camera case is a good selection of filters.
Filters are good news and bad news.

Filters that enhance contrast by absorbing ultraviolet light. Filters that alter tonal values in black and white photos Filters that alter the color temperature of light Filters that alter color Filters used with black and white film play quite a different role than filters used with color film. The notable exception to this rule are neutral density or polarizing filters, which because of their neutral absorption characteristics serve a dual purpose. Polarizers let you deep and intensify blue skies, achieve vibrant color saturation, reduce or eliminate or greatly reduce glare and reflections from non-metallic objects and translucent surfaces surfaces, like water or glass, and minimize haze in both color and black and white photos.
