I found the Nokia Lumia 1020 did an excellent job overall in most situations. Colors looked good and true to the scenes. Exposure is a little dark on the High Res setting, but I assume Nokia did that to expose for the highlights knowing people would make some adjustments later on. However, high res images are JPEGs, not TIFF or Raw files, which means there will be some quality and color information lost in order to accommodate the smaller file size.
Overall, though, the Nokia Lumia 1020 has the best camera in a phone I've seen yet. Plus, this device offers the best options for getting creative with images while not affecting the original capture.
