ISO 800 & 1600 samples

K10D images shot at ISO 800 & 1600 in my living room with fairly dim ambient ligting, as indicated by the aperture and exposure time I needed to use. First set of images came from a RAW file shot at ISO 800 with 31mm lens; f/1.8; 1/8sec. I processed the RAW file in-camera to produce both color and BW JPEGs. Second set of images came from a RAW file shot at ISO 1600 with 31mm lens; f/1.8; 1/15sec with same processing as the ISO 800 image.
