Photo quality from the W570 is very good for its class, but like most compact cameras it still stumbles at higher ISOs. Photos at ISO 80 and 100 are relatively sharp with very good fine detail and low noise. At ISO 200, subjects soften some, losing a touch of sharpness and fine detail. At ISO 400, images get noticeably softer and there's an increase in noise in darker areas of images. If you're printing at and below 5x7 inches and not doing heavy cropping, the results are very good. Photos at ISO 800 and 1,600 look painterly from noise reduction, so subjects will appear soft and smeary; it's even worse at ISO 3,200 making it unusable. Colors get muddy as well, especially at ISO 1,600 and ISO 3,200; you'll probably want to reserve these two highest sensitivities for emergencies when you need to shoot in low-light conditions or get a faster shutter speed regardless of the results.
