Once I successfully photographed the four eggs in a birdsnest that was within 2 ft. of the ground. This was accom-plished by raising the rear member of tripod to such an eleva-tion that the lens could be pointed into the nest; the said mem-ber being there—while tied firmly to a substantial post of fencenear-by; allowing a time exposure with a small stop, and an.ortho plate with color filter to be used.
