I must admit, this was my first time using ID-11. I had laying around some ID-11 and I thought I would give it a go. I mixed as instructed for 1 liter and used my best judgement on development times based on what others had experienced and the Ilford recommendation for Delta 400. The negatives came out somewhat over developed?, and what I would describe as thick or dense. If I were to guess, I would say that the developer might have been too concentrated? I ran two rolls, and the second fared better than the first but they still seem very dense. The film base is not clear. Its as if the developer left some of the halides on the base. I might have gotten a few shots that are printable... The Fixer I used is the same as always, Ilford Rapid fix. Temperature was 68f for 7.5 minutes. There is one frame of the roll that SHOULD be totally clear due to a camera malfunction, but is not - like the developer didn't even notice that frame. I should say I have never experienced this problem with Ilfosol S. I have not included a scan yet but will as soon as I get near a scanner. Has anyone else experienced issues with ID-11?
