 From 1963 until its July 1978 issue, Yamagishi edited "Camera Mainichi," and was widely admired both for the quality of the photography he was able to present there and for the encouragement he gave to young photographers.During this period advertising was attracting some of the most talented photographers, and Yamagishi was particularly noted for the way in which he persuaded photographers working in advertising to pursue their own photographic interests during their spare time.As an editor (and curator), Yamagishi had the knack of evaluating and selecting photographs much faster than his peers.
