See how this develops

High street film processing is not what it use to be of ten years ago since I used it. Unfortunately it's a lottery as it's the weakest part of the chain where you have no control. In this part of Norfolk it is not so readily available to walk to a specialised film lab. I already changed from one source to another due to bad processing. So since November 2008 when I started using film again I have had three rolls with errors in developing out of eight rolls. But in perspective this does mean it is in less than a dozen images out of a total of 192. With just these 3 recent images that you can't repair in post on the computer.

So a search for consistency may mean self development or mail order film lab.
