I was a customer of Metro, and I've now used the Ag lab a couple of times, the things they both have in common I.M.O that both their C41 and E6 work is excellent, some of the cleanest I've ever seen with no dirt scratches or drying marks on the negs. or slides and at very reasonable prices, however the big improvement with Ag Photographic has been the turn round time, the last C41 order I sent to Metro was about two weeks, the one I sent to Ag recently was three days from posting to it's return,
I can highly recommend Ag.
