-===== Rules of thumb ===== 
-The table below suggests how to select film exposure index (relative to box-speed) and adapt film development time (relative to datasheet) given an expected subject brightness range (SBR).[(biblio:Lambrecht2011)] 
-^  SBR ^    EI    ^  Time  ^  
-|  L |  -        -     | 
-|  N |  -2/3    |  -15%  | 
-|  H |  -1 1/3  |  -30%  | 
- 
-The table below suggests how to adjust film development to accomplish N+/- development. 
-^N-1 | -15% < N-1 < -25% | 
-^N+1 | +25% < N+1 < +40% |

-Minst 100ml konc per 80sqinch = 4st 4x5 
-175ml + 350ml = 525ml 
-160ml + 320ml = 480ml

-XTOL sägs ge bättre skuggteckning, samt att den håller ner högdagrar något. Lämpar sig bra för motiv som är "direktbelysta" (enl Thomas Bertilssen - photrio)
