According to Megapixel.net: "And indeed, when the frame contains very strong contrasts, the LD glass that is part of the lens of the C-770UZ is effective at limiting chromatic aberration to the extreme corners of the frame.", "By default, saturation and contrast are a bit conservative, and with some subjects a slight boost in saturation can be quite beneficial.", and "With digital cameras, the slower the shutter speed of the camera, the more noise gets a chance to accumulate in the image. Likewise, in low light, noise augments as the sensitivity of the CCD is increased. For the C-770UZ, at its starting sensitivity of 64 ISO, photos are noise-free; while at 100 ISO images begin to show a bit of noise in uniformly coloured areas and in shadows. When sensitivity is increased to 200 ISO, noise is much more readily detected; at 400 ISO noise shows clearly."
