Sometimes I see in the Exif exposure value (from a photographic contests site) numbers like 10/4000 or 301/100000.
I guess 10/4000 means 1/400 but what does 301/100000 mean?
Is it due to some Exif read or write error, or is there a meaning that I don't know?
P.S.: If needed I can post some link to photo with this values
