While the A3100 IS might not have much in the way of features, it does have excellent photo quality for the money. Like many compacts in its class, there's a noticeable shift in quality at ISO 400, so the A3100 IS performs its best below this sensitivity. In other words, the more light you have the better off you'll be. Unlike its linemate, the A3000, this camera has less visible noise when photos are viewed at 100 percent. Combined with its higher resolution, you get a little more flexibility when it comes to larger prints and cropping.
Colors are not always accurate, but they sure look great. With rare exceptions, subjects turned out bright and vibrant. Exposure is good, too, though highlights have a tendency to blow out--typical of its class.
If you're interested in the A3000 IS' creative scene modes, here's a idea of what they can do. The top photo was taken using the camera's standard Auto mode. The middle shot uses the new Super Vivid option, and the bottom one was taken with Poster Effect, which creates color banding where there would normally be smoother gradations.
