问题 Is there anyway (commandline tools) to calculate MD5 hash for .NEF (also .CR2, .TIFF) regardless any metadata, e.g. EXIF, IPTC, XMP and so on? The MD5 hash should be same once we update any metadata inside the image file. I searched for a while, the closest solution is: exiftool test.nef -all= -o - -m | md5 but 'exiftool -all=' still keeps a set of EXIF tags in the output file. The MD5 hash can be changed if I update remaining tags. 回答1: ImageMagick has a method for doing exactly this. It is

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . Are there any Pythonic solutions to reading and processing RAW images. Even if it's simply accessing a raw photo file (eg. cr2 or dng) and then outputting it as a jpeg. Ideally a dcraw bindings for python, but anything else that can accomplish the came would be sufficient as well. 回答1: A while ago I wrote a libraw
