I only once got a film processed & scanned at a high street lab for speed, needing the scans for the next day. It was the biggest mistake I’ve ever made. They did 120 so I mistakenly thought they knew what they were doing. I’m relatively new to the forum on here so I will not name the lab.
When I got the results back the negs were ruined, being scarred, covered in grit and other rubbish, as a result the scans were terrible. Let’s just say they got a very stinky letter and I’ve never been back.
Now I get my b/w done at Ilford and my colour done at Loxley’s in Glasgow.
I’ve tried scanning at home, I have a Epsom Perfection 2450, but I’ve not got the hang of it and have never had a satisfactory scan.
