What do you considering the upper limit for ISO?

As someone else mentioned it is different from shot to shot, but it's not that hard to get good results on most shots. |

It depends on the shot. With my 30D I consider ISO 800 good enough for anything,
in some cases using Noise Ninja, carefully. If you are doing a night shot with only a few areas of high brightness, and lots of dark where just want "Zone 1" or "Zone 2" brightness, and would like to emphasize the dark original setting, the equivalent of ISO 12800 is quite artistically OK.

As someone else mentioned it is different from shot to shot, but it's not that hard to get good results on most shots. Likewise for all ISO400 to ISO800 shots on P&S cameras. I keep my P&S cameras set to a default of ISO200 or ISO400 because the sensors in these particular cameras are exceptionally clean. Noise levels in sensors vary from camera to camera of the same model number due to subtle manufacturing differences from silicon wafer to wafer and also during the process of laying down the circuitry and other layers. Just as all pros sample quite a few lenses to find and be happy with one, all pros that use P&S cameras sample a few of the same model camera before they are happy with the sensor that was installed within it. Noise levels also vary greatly depending on ambient temperatures, something that few seem to remember. When shooting winter scenes I can use up to ISO1600 with little to no noise. I think it would be interesting if car sales were all based on the test results of a lemon that the road-testers happened to get. Further proof of manufacturing differences in circuitry from camera to camera of the same brand and model number: One of them that I use for videos even has exceptionally clean audio circuitry in it, when compared against dozens of the same model number where audiophiles reported a slight low-frequency noise being recorded in a completely quiet room. Confirmed when I uploaded a similarly recorded audio sample from my own camera of the same model for them to compare. They were astounded that the audio side of this particular one that I own was so exceptionally clean compared to theirs. Luck of the draw this time. I wasn't aware of this slight problem before purchase. Nearly studio-quality 44kHz stereo audio recording contained in a P&S camera. Quite the nice thing to carry for an advanced nature photographer where recording animal and other nature sounds are an important part of the required documentation process. (You should hear this frog I found in the tropics one time. It has 7 different calls, repeated at random. I never heard anything like it before in any amphibian species. I daresay nobody else has either. Like some songbirds that vary their songs. I was quite astounded and realized this needed to be recorded. Luckily it is now documented, all thanks to a P&S camera and an experienced pro that happened to be in the right place at the right time.) For the casual buyer the quality of the electronics in their camera is a luck of the draw. For the pro it amounts to buying habits based on years of experience and testing things for yourself. I can easily keep ISO200 or ISO400 as defaults on all my P&S cameras without a concern. Considering that I've religiously used ASA25 and ASA64 films all my life on all manner of subjects, I find zero drawbacks at those ISO speeds. They are more than enough for any experienced photographer. With the advanced noise-removal software available, when used properly with experience (like any tool should be used), ISO1600 under most circumstances is not even a concern. |
