I'm currently writing a software to analyse microscopy images. To give the user a better experience, i want to automatically extract as much information about the image as possible such as the x/y-resolution and so on.
I don't have a problem to extract the meta data from the images, but came across a (in my mind) weird choice about the storage of additional image data. At least for the images i used, the software tag (tag 305) is used to store the magnification and the names of the channels in BGR order. The copyright tag (33432) seems to store additional information, in my case about the used cell line and what was detected (maybe used general user input).
My question is: Is this odd usage of tags common practice so that one can use the information given in such tags?
