I don't think any Ilford developer can be diluted to the extent that Rodinal can be. Ilford recommend Ilfosol S or ID-11 1+3 for sharpness (which I guess is what you want from Rodinal negs). For economy, if you do not want to make up from powder, I think Ilfotec LC29 is the most economical, mixed 1+19Andy K said:Is there an Ilford developer that can be diluted like Rodinal? I first used Rodinal for reasons of economy, getting 50-odd developments from a single bottle of dev saved me a lot of money. Now I use Rodinal because I love the negs it produces and I know it pretty much inside out. So I am not looking forward to having to use developers that don't give me the economy or look of Rodinal.
(I have also tried DD-X, but it is not as economical as Rodinal although I do like the negs it produces.)
Alternately, if you want to keep the Rodinal look, Retrophotographic stock Adox APH09 which is allegedly the original Rodinal formula.
