So, after hearing Dave on the Sunny16 podcast say that stand developing was really easy I decided to have a go myself. I've done lots of 'normal' B&W films but fortunately I have some Rodinal. I shot some FP4 and put it in my Paterson tank with some Rodinal at 1:100 at 20 Celsius. I gave it a gentle five-second sworl at the start, tapped it then left it for an hour. I then used a very dilute stop solution. I have to say, I'm really pleased with the results, so thanks Dave. These have been lightly modified in Lightroom. I think I'll be using this method a lot more in the future. It'll be interesting to see how it works with Tri-X.
