I've exposed and processed six sheets of 12x20 FP4 so far, and here's a short report. I am developing in Ilfosol S diluted 1:14 (more on that later...), in 16x20 trays. 9.5 mins @ 68-70ish deg. f., one sheet at a time. First sheet had tremendous underdevelopment in the center of the sheet, so I decided to go straight to the brush. I am using the Richeson 'Magic Brush', 2-inches wide and was brushing in random patterns all over the film for the entire development. After looking at a few sheets I went to brushing for a minute, resting for a minute, until the development was done. I have no scratches at all, and the development is very consistent, complete and most importnat of all, it is even in all regards. I am wondering if anyone has a different technique to share or any thoughts on why I would brush continually vs. alternating brushing/resting? Frankly I just thought my arm could use a rest, so I went to the brush/rest technique. The negatives are being rated at ISO 50, which I believe might still be a little fast. The negatives when developed are generally quite flat, except in areas of extreme overexposure, such as bright sky from inside a potato-cellar (very dark). My best exposure, straight late afternoon sun, high diffused clouds, moderate contrast range, still looks very soft & flat. I am using Ilfosol S because it is the developer that Ilford recommends with FP4. I am using the 1:14 dilution in order to fill the entire tray. I am thinking that the 1:8 dilution might be a little punchier for the development. Short of PMK, which I am tempted to jump into anyway, are there other developers and times which might result in a slightly contrastier negative? Just looking for some general feedback about the brushing development technique and maybe some ideas about rating the FP4 and development. Thanks! Oh...no prints yet, sorry.
