What do you considering the upper limit for ISO?
"RichA" wrote in message
... Lets say you aren't pretending, like so many do that you can take really good images at high ISO. Where do you draw the line? Canon and Nikon are now boasting 100,000+ ISOs for their latest offerings, the Canon isn't even FF! But lets say you shoot with a D700 and you have the luxury of going with either 3200 or 6400 ISO. Can you produce a shot worthy of keeping at 6400 ISO? Or are we just kidding ourselves that the output at that ISO, or from any camera is acceptable? I shoot a D300. IMO, beyond 800 ISO I have trouble accepting the images as really good. I'm talking about non-noise reduced raw images. Sometimes, it's possible to use NR and not make the picture look like crap, but the leeway is narrow. Hello RichA. I usually start my 50D at 400 ISO but I'm happy to use a 50D at 1,600 ISO. I have used it at 12,800 ISO but very much as a "get what you can" move. It's a bit grainy at 12,800 ISO. I do like night scenes using ambient light so that's why I like to try high ISO settings. In case you wonder why I start at 400 ISO, it is because I used to use 400 ISO print film in my 35mm and APS bodies. I did try 1,600 ISO print film a long time ago but it was a bit grainy. Come to think of it, I used some 400 ISO "own brand" print film that was as bad as the 1,600 ISO print film. My guess is that this "own brand" film was a couple of generations behind the "state of the art" 400 ISO print film. Hope this helps. Regards, Rog. |
