OK, it's not THAT cold but ambient temperature in my home is about 62 F right now and I've got a hankering to develop some prints. The plastic tub I have for a water bath is not nearly wide enough for my 3 trays and once I take the chems out of the water bath and pour them in to the trays they won't stay at 70 for long. Now I'm thinking about doing this at room temperature to be consistent. I'll be printing on Ilford MGFB Warmtone and developing in Ilford Multigrade 1+9. Ilford recommends 2 minutes at 70 degrees, how much do you think I should add for the 8 degree drop? I've tried their time/temperature chart for film developing but it does not have times short enough for printing. Thanks for the help!
