Overall, the photo quality is very good from the Samsung PL200. There isn't a noticeable shift in quality until ISO 400, where subjects get visibly softer even at smaller sizes. In Smart Auto or if you have the camera set to Auto ISO, the PL200 seems to use ISO 400 as its ceiling, which is good for getting the best possible photo, but bad if you're shooting indoors or in low-light; the PL200 will go with increasingly slower shutter speeds, which means you need steady hands and still subjects. ISO 800 is somewhat usable for small prints and Web use, but colors look off. I don't recommend using ISO 1600 or 3200 as there are just too many problems with color, noise, and noise reduction to make photos worthwhile.
