We recommend storing unprocessed films in a cool, dry place between 10/20°C - and, if possible (before and after exposure) in their original packaging. We advise you to store processed negatives in a cool, dry place between 10/20°C and in the dark.
The downloadable chart gives our recommended times for the two processes with APX400 Film. All the times quoted are based on intermittent agitation in standard 20°C tanks (agitation for the first minute, then agitation every 30 seconds). We recommend reducing these times by up to 15% if continuous agitation is required. Also, for rotary processors (without pre-rinsing), these times should probably be reduced by up to 15%. Please note that we do not recommend pre-rinsing as this can lead to uneven processing.
