There is a story about a godol that was being photgraphed by Ed Bernstein and Mr. Ed Bernstein missed the shot he wanted and asked the rosh yeshiva to “do the pose again.” The rosh yeshiva said absolutely not but was willing to stand and smile so Mr. Bernstein can get the pictures he wanted.
This is gadlus because the rosh yeshiva had patience and was at the same time teaching no fake redo’s. If you miss the shot you miss the shot and the rosh yeshiva was willing to do whatever it takes so Mr. Bernstein can get his few pictures.
There are amazing stories about Gedolim and what they say is right and wrong with editing and the general shailos that come up for photgraphers.
Mishpacha Magazine had stories by Ed Bernstein a couple of months ago. It’s a must read.
Rav Gifter Zt”l was also known as a no non sense person and would not go in for any fake stuff. Rav Giter never minded being photgraphed as long as it was bekovidig Rav Gifter would never go in for faking photographs. It’s one thing to edit for tznius purposes or because someone looked horrible in the picture but to change an appearence to make it look like something of what the place or picture is not, Rav Gifter said many times it is sheker.
