Thanks for posting the pics inark - just got back from torquay tnite. Some of them are not too bad considering the low-lux [light]. Did you boost the contrast / brightness on those or not? [this is usually where the *grain* comes from].
The standard bolt-on / built-in flash's in most cams esp. digi are pretty crap for night use, dusk is ok but thats about it. I willl bring a professional [sLR] kit along one day if i can be stuffed!
BTW, didnt someone say that a "pro" would be there taking shots? hmm, or was that a ploy to get the numbers up? hey?
