Hi everyone. I developed two rolls of Kodak Tmax 400 last night. They both came out fogged down the middle as a result of persistent emulsion and with a serious purple tint. The tint was not slight, but severe. I have developed several rolls without any issue, the only variable this time was the fixer. I used the following procedure: 2 minute pre-soak Kodak HC-110(b) @ 20° Ilford Stop @ 20° Rollei RXA 1+9 for 6 minutes @ 20° 5 X 20 turns rinse then a further 5 minutes open running rinse +- 30 seconds in 1:100 Wetting agent I never bothered trying another fix. I read another thread here that states a pre soak is a waste of time and a second fix can solve the problem. I also read that the purple hue is not problematic, however this was severe purple hue with a thicker streak of fog running down the middle of the roll (120). With the pre-soak, the soak comes out dark blue. Could there be a residual dye in the mix? I have developed a few rolls of Kodak normally using Ilford Rapid fix instead of the Rollei RXA. Could it be the fixer? Thanks for the input.
