interesting question. I think it depends on their skills. I think if they know light and know their subjects they can do well shooting anything. Capturing the image in the right light with the right compositions is important but even ansel adams would have told you that image production is a process and that the post production process is critical. little in that regard has changed today.

According to his books, AA had an idea of what he wanted a shot to look like and he usually spent a great deal of time in the lab making it look that way.

I think with today's technology average photographers with the proper training and skills can look like great ones.. . .
