Submission + - Photoshop silently destroys your pictures
An anonymous reader writes: Like most current graphical software, Photoshop makes computation faults when scaling or filtering images. Depending on the kind of image details, the losses range from negligible to severe. Even scientific institutions like the NASA publish images that were damaged by these faulty software. In common image file formats, the luminosity of the pixels is encoded using an exponential scale, to save space. When computations are performed on the pixels, the exponential scale must first be converted back to a linear scale, which reflects the real luminosity of the pixels. This conversion is never made...
