Photo quality from the H55 is generally excellent for its class, but like most compact cameras it still stumbles at higher ISOs. Photos at ISO 80 and 100 are 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. However, this is only visible when they're viewed at 100 percent. If you're printing at and below 5x7 inches and not doing heavy cropping, the results are very good. Photos at ISO 800 and 1600 look painterly from noise reduction, so subjects will appear soft and smeary. Smaller prints will little or no cropping is possible, but not much else. ISO 3200 isn't good for much beyond Web use at small sizes.
