More times here.

For anyone looking to experiment or economise with DD-X it can be used at dilutions higher than 1+4. I would not try it for push-development or with Delta 3200. The higher dilution can give a similar increase in acutance as comparing ID-11 stock to 1+1. I have seen the times posted (by snappers whose opinion/judgement I respect) that suggest adding half again to the times established for 1+4.
