Hi all, As i'm getting into developing b&w all on my own like a big boy, i'm learning there are different "grain" type b&w films. Some giving better contrast/'sharpness'/etc than others.... I've searched about this, but simply can't locate a succinct answer. I can find lotsa heavy chemi-garble (which i can't decipher....), but nothing that makes sense.. I'm using Xtol developer as it's the only one i have/can get, but really like contrasty images.... Help!!!
