Maybe best to ask Ilford how this related to IV. It seems > most of the discussion on the list is Digital printing these days... ;) Hook > cast, line set.. <G> lol Hi Neil and Neil! The Multigrade IV settings you require are listed in tables 4 and 5 of the instructions that come in every box of MGIV paper. Table 4 gives single filtration values (shorter exposure) while Table 5 gives combination values to enable you to change more easily from grade to grade without re-testing. Rather interestingly Ilford includes the Focomat specifically in Table 5 but it is excluded from the single filter value table. Here goes Leitz Focomat V35 with Multigrade IV Grade 00 135Y/6M 0 105Y/12M 1/2 77Y/11M 1 67Y/17M 1 1/2 52Y/28M 2 39Y/43M 2 1/2 32Y/51M 3 23Y/62M 3 1/2 14Y/79M 4 10Y/95M 4 1/2 15Y/154M 5 0Y/200M Hope that helps David Prakel - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html - ------------------------------------------------------------------------------ This message is intended only for the personal and confidential use of the designated recipient(s) named above.
