A measurement of charm lifetime from the Fermilab fixed-target photoproduction experiment was presented. The analysis technique was described with special attention to the determination of the systematic uncertainty. A systematic uncertainty of ±0.23% due to absorption was determined. The measured value represented an improvement over the present world average.
