Check out an evaluation of photo quality from the Casio Exilim EX-FC100, one of the company's high-speed-shooting compact cameras.
There are plenty of reasons to buy the FC100, but photo quality probably isn't one of them--especially if you're going to be printing or viewing them onscreen at 100 percent. Regardless of ISO, photos look too processed with visible noise/artifacts and are never very sharp. Basically, you're good to ISO 200 before noise and suppression cause color shifting and significant loss of sharpness and fine detail. If you're using them online or making smaller prints (5x7 inches and below), you'll get decent results.
The FC100 features a handheld High-Speed Night Scene mode. With one press of the shutter release, the camera captures multiple shots and then stacks them up to produce a photo with minimal blur from hand shake. However, it still needs to use a high ISO--in this case ISO 800--so despite no blur, there's still plenty of noise/artifacts, off colors, and softness. On the other hand, I printed this at 4x6 inches, and it looked better than the full-size picture would lead you to believe.
Considering the lens on the FC100 is fairly narrow by current standards, it's surprising to see wide-angle distortion (top). There's some slight pincushioning at the long end (bottom), too, though I doubt either would ruin a photo.
Colors up to ISO 200 are pleasing and natural. The camera has sliders for tweaking saturation, contrast, and sharpness, too, in case they aren't to your liking. Exposure is decent, and the camera does have an effective image brightness option.
