I 'll buy the liquid A-B version to develop 6x6 medium format negative in TANK.
Film Tmax 400 and Hp5
Do you suggest to me the double-bath or the stand development? To do the stand developer is it better use low speed film like Tmax100 and fp5 than the Tmax 400 and Hp5? I read by Sandy King that high speed film may give lots of problems with stand development...
Anyway, please tell me if the both processes is right in this way;
STAND FOR 6x6 film in tank :
work temperature 21°C ( 70°F)
5 minutes pre-soak (how do the agitations?)
pour in the tank the solution 2:2:400-500 2 parts A + 2 parts B + 400-500 parts of water
agitate vigorously for 60 second then leave it for 45-60 minutes with just some 5 seconds agitation in the middle.
stop just in water, agitate the tank for 30 seconds
fix bath in TF4 for 6 minutes (how do the agitations?)
wash in water for 30 minutes
DOUBLE-BATH in tank : (it should give more acutance and sharpness than the one bath develop with minimal agitation?)
work temperature 23°C (75°F)
1+10 dilution of both parts A and B
pre-soak 5 minutes
7 minutes (15 % time more than the usually 6m because in tank) in part A. 2 inversions at the start then 2 at 1/4 , 1/2 , 3/4 points of the develop
5 minutes 45 seconds ( 15% time more than the usually 5m because in tank) 1 vigorous agitation for the first minute the 2 or 3 inversions at 1/4 , 1/2 , 3/4 points of the develop
pour water and leave it for 5 minutes
fix bath in TF4 for 6 minutes
wash in water for 30 minutes
Is it all right? Any suggestions?
Thanks.
