Like most point-and-shoot cameras, the TL320 hits a wall at ISO 200. Photos are less than sharp from the get-go and there is some graininess when viewed at 100 percent, particularly at ISO 200. At ISO 400, the noise reduction makes things hazy and soft, though a good amount of detail remains. This, of course, increases at ISO 800 and 1600. While photos taken at ISO 800 are still usable for the Web and small prints, those at ISO 1600 have noticeable color issues.
One of the many features Samsung includes in the camera is its Auto Contrast Balance (ACB)for help with backlit subjects or high-contrast areas. The top image is with it off, the bottom with it turned on. It clearly works.
Though some colors come across a little richer than others, overall performance is very good. More importantly, if you don't like the colors produced by the TL320 there are several ways to tweak things before and after you shoot.
