I've switched from Windows to Ubuntu (Linux) and I'm having strange metadata problems with the Darktable program. The metadata I enter in Darktable doesn't upload to Shutterstock and seems hit and miss with Dreamstime. However, if I put in the data, save the file then upload to Photoshelter the data is there; and if I then save the Photoshelter file back to my computer and re-upload to SS then all the data appears.
Does anybody else have this problem? The Photoshelter work-around is a bit clumsy and I don't understand why this should happen. If there's a simple way of getting the data read without going through Photoshelter it would be better.
