Overall, the photos produced by the ZR1 are very good to excellent depending on if you care about how pictures look when viewed or printed at the full 4,000x3,000-pixel resolution. There's visible noise at all ISOs, but it isn't until ISO 400 that it and noise suppression combine to soften detail. At ISO 800, photos take on a painterly appearance, but fine detail is still fairly good. Though there's still some detail at ISO 1,600, photos are for the most part unusable because they are covered in faint yellow splotches along with a good amount of noise.
Purple fringing was minimal in high-contrast areas, though it did still appear on occasion as in this shot. In fact, this is one of the few test shots where it was visible and it's pretty faint at that.
Panasonic's Intelligent Exposure in action. On the left, the feature is turned off while shooting in the camera's Normal Picture mode. Turn it on and you get the image on the right, which obviously brings out the ground cover below the flower without overexposing the white. While the left is more dramatic, the right is more natural. Intelligent Exposure is always on in Panasonic's Intelligent Auto mode.
