Due to size/space/weight issues, I've been forced to leave my Canon DSLR kit behind while I'm deployed in Iraq and shoot with my Olympus SP-350 digicam instead. At ISO 50, its' noise level isn't too bad, and when converted to B&W (I use Convert To B&W Pro) with no noise reduction, it adds a bit of texture to the image without looking too "digital". For color shots, I use Neat Image; the chroma noise detracts from images.
