I could not figure out why my negatives suddenly seemed to be telling me that my camera had a light leak. It certainly appeared that it had a light leak. So I tried a different camera. Same issue. Maybe it was the caffenol solution I was using. Fresh batch. Same issue. Switched to Xtol. It never fails. It failed. So web, please help me... and it did. An obscure site with a single post told me I was not fixing my negatives long enough. I had usually fixed for about 3 minutes, because I was unable to wait to see the photographs I had taken. Stupid. It also suggested that I could re-fix any zebra negatives I had laying around, and the stripes would vanish...and they did. So, thank you Google and random search result. You fixed my zebra.
