I am just wondering what ISO other CiC photographers use as the maximum when shooting with a Canon 7D.
I usually keep my ISO at around 160 for brighter days and 320-400 for darker days and for fast action when I need to keep my shutter speeds high.
For night shooting, I most often use ISO 800.
However, I have recently purchased the NIK Software Suite and am going to experiment using ISO 1,600 to even 6,400 with the NIK noise supression software.
I will use whatever ISO is needed to get a shutter speed which will allow sharp imagery. I would rather have a noisy sharp image than an unsharp image without noise.
I also often use flash to supplement the lighting. Even the little 270EX bounced into a Joe Demb Photojournalist FlipIt will provide just a bit of fill to supplement avalable light. However, the 550EX or 430EX will do a great job when bounced into the Demb Flash Diffuser Pro - even when there is no overhead off which to bounce...
