I have read quite a few times that Gadget G. and others use the 'dry measure' method (tsp, tbsp) to quickly make home brew developers. I have tried it and it seems to work fine. Is a scale really necessary? Do Kodak, Ilford measure hold that kind of precision in their packaged developers? I do have a 505 grain scale for the really small quantities but I like to 'scoop' for the other ingredients. Saves time, is super convenient, but am I risking upsetting a delicate balance? -F.
