I just started developing BW film on my own. It's cool!! I use Adox CHS 100 4x5", developed it in ATH 09 (a Rodinal clone), in Jobo Expert 3006 tank on a Beseler base at ~25 rpm, reversed the drum each minute.
For my first run, I used development times as suggested in the Digitaltruth database. All went fine (I suppose in no little way thanks to the forgiving nature of the materials used), apart perhaps from noticeable grain visible in sky portions of the test shots, but that's Rodinal I guess. For now I'll stay with what I have.
I find the development time a bit too long, it's 13 min for normal develompent at 1+40 dilution, at 20°C. Particularly the N+1 time, 18 min, is a bore. If I increase the development temperature and/or decrease developer dilution to speed things up a bit, will there be any negative side effects? (If I recall correctly, increasing both dilution and processing time has a side effect of making grain even larger, but I'd be doing just the opposite.)
