Unfortunately, I can’t find any information on how to develop APX 400
in Microphen,
pushed from 400 to 1600. It’s supposed to give good results,
but how???

Mila,
There are actually photographers who work this way, using Microphen with a 1+1 dilution for about 55 minutes at 20 degrees on Fomapan 400 or APX 400.
The exposure should be at 6400 ASA.
The image effect is ‘dramatic’. Shadows become completely black, the mid-tones take on a lithographic-like effect and the highlights (hopefully) show good separation.
But this is definitely an experimental approach!
You can’t ‘turn’ any 400 film into a 3200 or 6400 film.
If you’ve had an exposure for 3200, try 40 minutes.

Hi Mila,
The development time calculator on Phototec gives a time of 41:48 for the old APX400 in Microphen 1+1 at a push of +2 (i.e. 1600 ISO) and a time of 23:06 for Microphen stock solution. The times listed there are calculated and usually serve as a pretty good initial guide.
So Mirko’s recommendation of 40 minutes works out. Although with push processing, the APX-400 becomes even less than it already is.
Well, if that’s your thing… It certainly won’t produce that lovely Rodinal grain.
In my opinion, HP5+ is better suited to push processing. In Rodinal/R09/F09 or even in Ultrafin liquid or Microphen.
Best regards,

Hi Franz!
You don’t need to sign off as ‘Franz’ anymore – just use ‘Mr Rodinal’ – the fearless knight of the perfect grain. I’m not mocking you – you’re the one who practically single-handedly got me into using Rodinal. I’m absolutely thrilled with it!
