The image quality of the Canon IXUS 800 IS / PowerShot SD700 IS is nothing short of excellent.
Three levels of JPEG compression are available to record images, and the level that applies the least compression, and therefore guarantees the highest image quality, is the Superfine setting. Set to this compression level, the IXUS 800 IS / SD700 IS yields images that show no loss of detail, and subtle colours can be detected in both sky and foliage. Moreover, the Fine image quality, a compression level that yields file sizes that are half of those in the Superfine mode, offers an image quality that is often hard to differentiate from the Superfine level.
