|I've only shot one roll of either:
Ilford FP4+ was at least 10 years past its expiry and hadn't been cold-stored.
'So-called' AGFA APX 100 - this has been through re-formulations and, most recently, change of supplier. I can't remember which version I had, but have a feeling it might have been the 2010 'New' formula - the internet doesn't think this was an improvement.
Developed and scanned by AG Photolab (UK) to 3089 x 2048 pixels.
FP4+ Moderate round grain, probably coarser than if it had been fresh, and noticeable when viewed screen-size (let alone 100%). Nice dynamic range and contrast.
APX 100 Very fine, feathery grain and low in contrast meaning that smooth surfaces (or the sky) look smooth. Dynamic range likewise very good. The only downside is the grain which, when viewed at 100%, seems like ink blotting on paper - leafy things (trees / grass) in the distance look quite impressionistic.
They are noticeably different. I believe I am correct in saying that FP4+ was formulated in the 1980s - it has the old-school, grainy look that you might be after. Conversely APX 100 does a perfectly good job of rendering a scene in black and white, certainly better than some 400ASA films I've tried.
Personally, I'd like to give coloured filters a proper try and feel that 100/125ASA is probably still a little slow, so I'm looking at films in the 200-400 range.
