To speed things up, we don't decode tags unless they're asked for. Exposes a dictionary interface of the tags in the directory:: ifd = ImageFileDirectory_v2() ifd[key] = 'Some Data' ifd.tagtype[key] = TiffTags.ASCII print(ifd[key]) 'Some Data' Individual values are returned as the strings or numbers, sequences are returned as tuples of the values. The tiff metadata type of each item is stored in a dictionary of tag types in `~PIL.TiffImagePlugin.ImageFileDirectory_v2.tagtype`. The types are read from a tiff file, guessed from the type added, or added manually.
