Changing ISO Settings on the Canon EOS 20D
I have to admit that, although I routinely set the aperture and shutter speed on my 20D, particularly when shooting landscape photography, I've pretty much ignored my ISO speed. I've just set the ISO to 100, and pretty much ignored it. Now, I'm starting to wonder if I shouldn't be changing it, particularly when shooting in low light, such as indoors and/or in low light conditions outdoors (dawn/dusk). Apparently, the theory is that, as you shoot at higher ISO speeds, there's more noise in the sensor. Although, the 8.2 Megapixel CMOS sensor is widely reported to have a very low amount of noise in the sensor in any case. Also, people are apparenly using NoiseNinja or NeatImage to clean up the noise.
Here's a fairly in-depth discussion on the pro's and con's of using various ISO settings on the EOS 20D.
