Not "Delta." On your thing above a reviewer in one of the smarter photo magazines about 15 or 20 years ago said Rodinal at 1:25 looked identical to D 76 1:1. Not a bad thing but not what we use Rodinal for. The 1:50 dilution will bring out the extra sharpness of Rodinal and edge effects which make things appear sharp (like unsharp mask). But even though it is not listed plenty of people use it at 1:100 for the maximum sharpness and so on. This dilution also imparts a glow to the highlights with says "Rodinal at 1:100" For a while i compromised on 1:75 (no glow but better grain) and i found out other friends of mine here in Portland were doing the same. The more dilute the more time developing but it seems to work out alright. Also dilution does not make you loose film speed in most cases as you would think. It's usually a case of a constant or even added film speed because of the whole film compensation thing. If you've heard of that.
