Thanks to everyone for their help ...(posted 8379 days ago)The AGFA literature recomends 14m but typically I decrease that time by 30% to my developing techniques which increase the effects of the agitation and improvesthe eveness of the results.
My first shot was 11m and I think I am going to move towards 10m due to the density of the highlights. Unfortunately light conditions during the shoot (I chatered a plane and did some aerial shots of the Kluane Glacier) so I will have to compensate for the contrast differences with the paper.
BTW I develop my film using a 1/2 full tank (i.e. I use 1 reel in a 2 reel tank with enough chemistry to fully cover the 1 reel). The excess space in the tank greatly improves the effects of agitation and eveness of development. The downside of course is that it takes me longer to develop all of the rolls (sigh). I shot 12 rolls of 120 APX400 so my evenings this week are booked.
