[QUOTE="dtownley1, post: 565499, member: 20564"] I'd also advise against using auto adjustments in general. They tend to destroy tonal details in some parts. Check the histogram after you do an auto adjustment to see. Fozthedevil, do you mean a Nikon D40? Hmm, didn't know it only went down to ISO 200. That's odd. Just a general observation - dark images tend to show noise more noticeably. Also, different DSLR's handle noise differently. From my understanding, Canon cameras (until recently) have been superior to Nikon when it comes to performance at higher ISO speeds. I'm finding that out now with my D40x. I try to avoid shooting at high ISO's whenever possible. Photoshop has some pretty good ways of dealing with noise when editing raw photos. Be careful when editing colours though - say you want to edit the saturation or luminosity of some tones - it may grab some, but due to the noise, will leave others, resulting in greater contrast in the noise. I found this out pretty early when converting to black and white through raw - I kept getting strange tones and noise effects. Best thing to do, is keep adjustments to a minimum - you can't beat a quality shot to begin with. Another thing to experiment with, is HDR images. Photoshop can do this for you (through File>Automate if I remember correctly) but since it's still a new technique, the results aren't always great. Still, it could help with some of the tones. Haven't tried it yet with high ISO so it may not help, but it could help with the image to have a better tonal range, instead of so many dark tones. Hope that helps. [/QUOTE]
