LONG-EXPOSURE Effects

Under low-light conditions, you may have to extend your exposure times to a point of significant speed loss. With black-and-white films, the effect of this speed loss is partially offset by wide exposure latitude. Most color films require more than the normally calculated exposure when the lighting is unusually low. Also, the sensitivity differences between the many layers of color films can cause a color-balance shift, which means that you will sometimes need to use color-compensating filters to achieve an acceptable color balance.

When you must increase the indicated exposure to compensate for long- exposure effects, use a larger lens opening, if possible. Extending the exposure time will result in more speed loss, contrast change, and color shift. See the manufacturers data tables for your specific film to determine what exposure adjustment and filter may be necessary.

SHORT-EXPOSURE EFFECTS

Extremely short exposures produce essentially the same effect as long exposures: speed loss. There is also an increased scattering of exposed silver halide grains, the formation of smaller latent-image centers, and a lower rate of development at the latent-image centers.

The short-exposure effect appears as lower contrast or reduced density in the negative. Exposures of 1/10,000 second or shorter can cause this problem.
