  1. Re: Unsharp Masks - When Not Worth the Effort

    I was not considering masking for CDU-II, but now that you say it... it can be a good idea. Sadly CDU is no longer available, so that frozen stash is a last chance...
  2. Re: Unsharp Masks - When Not Worth the Effort

    O course... if stacking masks then a register is essential.

    It's easy, but also consider using a 120 format back in the view camera rear to shot 6x12cm for example. Color sheet film is crazy expensive compared to 120 format.
