What do you think is the sharpest B&W film

Buy some Rollei ATP 1.1 and it comes with it's own chemistry that's just as easy to use as any normal developer

 

Have a look at my thread on the subject here from last weekend

 

I like Ilford PanF+ at 32asa too

If you want the finest resolution, the two films already mentioned would be good choices as far as I know. But if you're looking for the impression of sharpness, a little bit of sharp grain can help. In Barry Thornton's book "Edge of Darkness" he illustrates this phenomenon well.

 

When I was young, I sought the "best" sharpness and chose Adox KB14 (20 ISO or 20ASA as it was then). It was certainly sharp, but a pain to use and I found it difficult to control contrast which was very high if I followed the manufcturer's instructions. Today, faced with the same film, I would overexpose a bit and develop for an extended time in rather dilute developer.

 

If I wanted the same level of fineness of grain today, I would try a 100 ISO new tech film like Acros 100 or Delta 100 and use a grain preserving developer like dilute Rodinal.

That does not call for special developing that you can get in todays market?? I did do a search in the forum so I did not use the word best because it is all subjective to ones taste.

Cheers Jan

Hi Jan,

I use Ilford FP4 (i like Ilford the best according to me)and Fuji Acros 100

Hi Jan,

Have a look here:

Gigabitfilm® GmbH formerly known as Agfa Copex Rapid Pan

and here Retro Photographic Ltd - Black & White Specialist Photographic Products

Hope this is some help

I would have said Eastman Technical Pan I have been through a 30 metre roll in the past and I still have two cassettes left. I developed in POTA, its chemical constituents are easily available.

Now TP is no longer then I would go for Adox/EFKE KB25 in Rodinal 1:100.

 

I dare say the Gigabit film is a super fine grain film, but what can it be developed in apart from its own special developer?

 

I would have to say the EFKE. It ain't perfect, get a hardening fixer and some Rodinal/R09 and you are sorted.

I think "sharpest" is just as subjective as "best". Somebody mentioned one of Barry Thornton's books. That is sound advice.

 

"special developing" is also a bit subjective. To me it is everything that excludes D-76, Xtol, Rodinal and their equivalents. Gigabit, CMS and a few others are special. To me they are generally not worth the extra effort that is necessary to familiarize oneself with them with starting with their low speed, continuing with skin ton and or foilage rendering and then printing.

 

TMX/Delta and Xtol rules. Or HP5 in Rodinal. Just get your EI and development time spot on. A densiometer and a few test films and some superficial knowledge of the Zone System work wonders

EFKE KB-25 AND EFKE R-25

KB-25 and R-25 are orthopanachromatically sensitized thin-layer black-white negative films of very fine grain, which proporties together with the coinciding grade provide the highest possible edge sharpness. KB-25 and R-25 resolving power is 115 lines per milimetre. These films find their applications particularly in technical and professional photography. Sensitivity of Efke 25 is 14 DIN (20 ASA, ISO 20/14° GOST 18), but by developing in coinciding developers effecting Efkes sensitivity utilization may be even twice increased to 100 ISO.
