Higher dilutions will give a compensating effect but through testing and documentation you can pull your film and get your highlights where you want them. Why not just get a larger tank. If you have two tanks with the same dilutions, you might risk over development due to the added time in between each step... You could just throw the extra developer away or wait till you have a few more rolls to develop or get smaller graduates to mix up smaller amounts. I don't know but it sounds like your making this way to difficult... no offense. Cheers(posted 8336 days ago)
