I do not think photoshop levels is a gamma correction! Anyone know what it is?
Photoshop 'Levels' allows gamma, white point and black point to be adjusted independently. This is not the first time I have seen differences in results between Photoshop and ImageMagick, and Photoshop is not gospel, however, the basic [photographic] gamma formula is known so the question and examples are interesting.
