Under normal, general purpose photographic conditions, depth of field is determined by the size of a geometrical blur circle on the negative or print. Under high magnification conditions, another means of measurement must be used based on the wave nature of light and the resolution of the imaging system. For this purpose, an effective depth of field was determined on the basis that no significant deterioration of image quality could be detected by means of resolution and Transfer function in the range of frequencies where the eye transfer function is at its peak. The experimental values obtained were compared with Rayleigh's quarter wave criterion to determine if the Rayleigh Limit is a good estimate of depth of field under these conditions.
