15. ntext does not imply a short coming of the film flash equipment or the camera but merely that the reciprocity law does not hold for very long or very short exposures times We also sometimes refer to these changes in film response to particular illumination levels as long exposure effects and short exposure effects 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
