As one who has benefited from the wide knowledge of fellow APUGers on films and developer combinations, I thought I could post some information I have gathered from using APX400 and simply opening the cassette packet to see what it had to say.
The information given below covers a range of Agfa developers and some of the following combinations are not mentioned in the Massive Development Chart.
I won't set it out as a table as the last time I did that it went awry
. Here goes:
APX100:Rodinal 1+25 = 8 mins. Rodinal Special = 4mins. Studional liquid 1+5 = 4 mins. Refinal = 6 mins
APX 400: Rodinal 1+25 = 10 mins. Rodinal Special = 6 mins. Studional liquid 1+5 = 6 mins. Refinal = 5 mins
It separately lists times for Refinal and Atomal FF for what it refers to as "Tank" as opposed to a daylight or small tank. These are:
APX100: Refinal = 7 mins
APX400 Refinal = 5 mins
APX100 Atomal FF = 8 mins
APX400 Atomal FF = 10 mins
One slightly strange ( or maybe not strange?) thing struck me. All times for APX400 are longer than APX100, which is what I'd have expected, except for Refinal which is shorter for both a small/daylight tank than "tank"
All times are for 20 degrees centigrade and agitation is continuous for first minute then every 30 seconds afterwards. I assume that it is one agitation every 30 secs but the instructions aren't specific on this.
I hope this helps some APUGers. I am not a user of any of the above developers( DDX does a good job for APX400) so now for some questions, if I may.
Can anyone give a brief explanation of what the differences are between Rodinal, Rodinal Special, Studional, Refinal and Atomal?
I wondered if Refinal might be the Agfa equivalent of an extra fine grain developer yet, if this is the case, the times seem quite short.
Why is there a difference between the Refinal times for a daylight tank and "tank". Indeed what does "tank" refer to?
Why isn't there a time for Atomal for a daylight/small tank?
Why is the time for Refinal longer for APX100 than for APX400? This seems to be the wrong way round. Normally I'd have assumed that the lower the ISO the shorter the time. It is for all the other developers.
