getexif() crashes when reading empty EXIF data from a PNG file saved by RawTherapy 5.8 #4676
Description
What did you do?
Converted a RAW file to PNG using RawTherapy 5.8.
Opened the image file with Pillow and called getexif()
What did you expect to happen?
Since the file has no EXIF data, the expected output is None or an empty dictionary.
pyexiv2 returns an empty dictionary.
What actually happened?
