I've had 3 priceless C-41 films out of 5 lost in the post on the way to a commercial lab that I sent in June. This has really got to me as the pictures were of a photographic trip to Istanbul. Only 2 of the 5 flms have been recovered. The commercial lab received the original lab envelope containing my films damaged with only one film inside. Each of the 5 films had a sticker on it with the lab address, my name and account number. One further film found its way to the lab a couple of weeks later so 3 films are still missing, now probably lost for ever. Next time I'm going to put my films inside a sealed plastic bag before putting inside the mailing envelope. Anybody have any experiences of ruined or lost films by commercial operators?
