ISO comparison
The regular, plain ol' automatic snapshots from the Casio Tryx are good to very good, but it's such an unusual camera that it's difficult to give it an overall pass/fail grade on photo quality. The camera seems targeted at people looking for something better than a smartphone or camera phone with photos suitable for online sharing. At that, it succeeds.
With plenty of light you'll get pleasing color, good exposure, and nice details. Once you have to use ISO 400, though, you'll get subjects that are soft and smeary. Noise and noise reduction increases above that,too, making photos less useable for cropping and larger screen and print sizes. For Web use and small prints, however, the high ISO results are OK (though I'd stay clear of ISO 3200 as subjects are just too soft even at small sizes).
The Tryx does have several shooting modes that take advantage of its high-speed sensor and processing to improve different things such as dynamic range and low-light performance, so what you see in this slide isn't the whole story. But, if you're the type to leave it in auto, I would probably skip this camera. Also, pixel peepers will likely not be happy with the photo quality regardless of shooting mode. Overall, the Tryx is a better fit for those looking for a secondary camera to have fun with than as someone's one-and-only pocket camera.
