A photographic technique for recording instantaneous plume and puff shapes uses two cameras operating simultaneously to obtain a stereoscopic image. Since the lateral dimension of the plume is not known with certainty, an error occurs in the determination of the lateral plume displacement from the mean. The data indicate that, for a sampling time of three minutes, the vertical dimension of the averaged plume is larger than the lateral one. An error analysis for the procedure is presented.
