When photography was one of my hobbies (40+ years ago), a couple or three decent transparencies from a 36 roll of film was typical (even good) if the frame was not posed. With negatives, one could enlarge just part of the photo to improve the final positive, so rather more forgiving than transparencies.
With ten grands worth of kit these days, one should be able to literally take thousands of frames, discard most, photoshop a few and finish the day with one or two or even a few memorable images.
I ‘messed up’ one piece today, with my mill. Not important as I’ll likely get it right next time – tomorrow, Sunday, perhaps next week. With wildlife there may not be another photo opportunity. Rather different scenarios, I would suggest.
I agree with Neil, but that does not always apply. My SLR was still a manual wind-on camera, back then. The different lenses were as important as the camera body – and then there was the film processing and printing to do later…
