I'm feel really uncertain at this point, becouse I've printed on MG papers only few tens' of prints. The amount of possibilities you can choose from it is enermous. I afraid it would take some time and lot of bad prints to take sense for what filter could be the best for that or another print... Yesterday I printed first time with 0 filter and was amazed how rich gray scale it can produce...

Gennerally I think question of contrast is - in some and sometimes relatively wide range - question of taste and there is nothing as "the best solution", or not "the best solution for everybody". But that is maybe more about my current uncertainty then about the facts... jk
