Hi,
Thanks for those really good answers.
Regarding the snapshot, where a moment in time is captured, such as sunsets, parties, friends, locations etc etc. I agree that most cameras including smartphones are plenty good enough. I have a 1/2 smart phone, that I've been using for years, with a 5MP camera, that I whip out for those situations.
My most fun period with a camera, was my 70s Pentax ME Super, with a pancake lens, and a 70-150 zoom lens. I think I enjoyed the taking more than the viewing, and did every experiment possible!! Occasionally though, I would get a really good and interesting bits of art, when I wished they were better detail quality.
Years later I bought a DeVere 1/2 plate enlarger, I told my mate. He had just bought a Kodak 1/2 plate camera. Talk about coincidence! Anyway, he lent it to me, and I studied Ansel Adams and his zone system. These cameras/film and tripod are heavy, so a day out in the forest with 6xfilms, was a trek, but it certainly made one concentrate before pressing the button. So I now have lots of B/W colour and colour transparency, large negatives.
In the above replies, film/digital detail comparison was discussed. I gathered that a good DSLR camera would be more or less fine, for copying 35MM film. I have a 35mm film transport from an old shop processing lab, that's been followed me around for years, that I could adapt for copying. (I also have a 35MM one that I am adapting for 8MM film copying)
When it comes to 1/2 plate copying, using the same DSLR, it seems I would have to make an XY plotter to make a matrix of 25 plus overlap, shots, for one film. I once cut a film into a 5X5 matrix, and made 25 prints, which looked really effective when pasted on a wall.
When I get time, I'll post a copy of a large print, with an accompanying, small section, to illustrate the detail, when detail is needed. (for those who haven't already seen what large format can do)
Thanks for all of the input.
C.
