Narrative:

I was in a descent from 12500 ft and cleared to 4500 ft. Before this we were doing photography and I had true altitude(QFE) dialed into the altimeter and didn't level off until 3700 ft with the current altimeter setting. I should have put the current qnh altimeter in as soon as we were done.
