How usable is ISO 3200 on Canon cameras?

[JohnG]

USM and Noise Reduction are always my last steps. 90% of the time I do USM first. But, if I had exposure problems and thus more noise I'll do the noise reduction first prior to USM. But usually if it's underexposed it goes in the trash - it's a rare shot that ends up with enough detail to save.

Do you ever use High Pass for sharpening?

[JohnG]

Never tried High Pass method- are you referring to one of the plugins for photoshop?

Always willing to give something new a try if it will improve things.

Have you been able to get better results from it as opposed to USM?

I get very acceptable images from ISO 3200... I happen to use NeatImage... I've actually printed some up to 13 x 19 and people are very impressed with them...

Also... the Sigma 120-300 f2.8 lens is absolutely amazing!
