I'm writing a script to calculate the MD5 sum of an image excluding the EXIF tag.
In order to do this accurately, I need to know where the EXIF tag is located in the file (beginning, middle, end) so that I can exclude it.
How can I determine where in the file the tag is located?
The images that I am scanning are in the format TIFF, JPG, PNG, BMP, DNG, CR2, NEF, and some videos MOV, AVI, and MPG.
