Pan F+ iso??

[Chad]

Having developed and printed from about a dozen rolls of Pan F+ is seem to me that this film is slightly grainier than the iso rating would suggest. I've been using HC-110 developer. It seems to be more like a 100 iso film judging from the grain at 8x10.

Has anyone else had this impression?

I should have mentioned that my comparisons are with Efke 25, 50, 100, & FP4.

Pan F is fussy stuff. Some people love it but I've never really got the hang of it. If I want (practically) grainless I'll shoot Delta 100 at 50 and develop in ID-11 stock. Anyway a bit of grain can increase the apparent sharpness of a negative.

I found this on the ilford forum recently:

Good morning, Michael,

Here's the information that I have used for several years. You will have to convert F to C, I still use F

Ilford Pan F Plus with Rodinal 1:50 (not 1:49 but 1:50)

Shadowless lighting: ASA/ISO 64 68F 11 min, 70F 10 min, 72F 9 min, 75F 8 min

Flat lighting (1:2/1:4)ASA/ISO 50 68F 8.5 min, 70F 7.75 min, 72 7 min, 75 6 min

NORMAL Lighting ASA/ISO 32 68F 7 min, 70F 6.5 min, 72F 6 min, 75F 5 min

Contrasty Lighting (1:16+/-) ASA/ISO 25 68F 6 min, 70F 5.5 min, 72F 5 min, 75F 4.5 min

Very Contrasty Lighting (over 1:16 - seldom ever used) ASA/ISO 16 68F 5.5 min, 70F 5 min, 72F 4.5 min, 75F 4 min

edit:

i must add, i like efke 25 in d-76 much more than panf+ in d-76. i think panf+ in d-76 is way too contrasty, but the grain seems nice. smaller and more accurant than efke 100 in d-76 and tetenal ultrafin+.

but the grains on efke 25 is literally invisible on a 13cm x 20cm print, when exposed at EI 25-50 (outside) and EI 25 (inside) and developed in d-76 for 6 mins (agitation first minute, then 10s agitation every minute).

I find that if PanF plus is even slightly underexposed, it starts to act funny. Likewise, it's picky about development.

I shoot it at 25 or 32 in most conditions. And process in HC110 1:100 for about 18 minutes. With very minimal agitation. Maybe 2 inversions every 4 minutes. If that much.

I've not done a direct comparison with the efke 25. But it behaves pretty well in general for me.

I have shot it in 120 and 35mm, it is really creamy in 120 and of course grain is not much of an issue in 120. In 35mm it is slightly grainier souped in Xtol and even 510 Pyro, the small amount of grain gives the image a sharper look. I find my self choosing Acros more often than Pan F these days.

Below are a couple images with Pan F+ in 35mm and dev. in Pyro.

I've found agreement in my work with what Shutterflower & Magus have said- PanF can be contrasty stuff. I've been running it in ID-11 1:1 at the box speed of 50 and getting manageable contrast, but in HC-110 the contrast does get out of hand easily, and the grain is much more than you would expect. Pan F at 25 or 32 is an excellent rating for those blisteringly bright days (that are over for this year in VT- humidity has arrived).

Play around with PanF some more Chad- it really is worth the effort to figure out how it works for your images- because large prints can be quite beautiful from this film. A quick test may be to shoot a roll of one scene- meter at 25, 32, 50 and then a blank frame. Repeat this to the end of the roll- clip test the film at several developing times and proof them all- use the blank space to write your developer/time on the film itself. You'll quickly get a handle on what to explore further.

Thank you for the input everyone. Its hard having so many developing variables to really know why a film looks the way it does (at least to my untrained eye). I'll keep testing.

ISO 32. Rodinal 1:50 for I believe 11 minutes.

I like this film.
