Found Film... What's Wrong?

To the person who shot Pan F and developed some months later....Ilford do warn that the latent image on Pan F is not as stable as other films and they recommend processing as soon as possible after shooting...however two months should be OK.

But in general, do not use long expired film for an important project. Do not use film you are unfamiliar with for such a project. Do not use something which was not intended for greyscale photography unless you are confident and experienced with the handling and processing of such film. Three good reasons not to use this Tech Pan for a graduation.

Strange to imagine that the latend image
of explicit Pan F is not very stable?
You have "white needle highlights" on Pan F when this will happen - am I right?
Or let us say very smalest black points on Pan F negatives like dust.
I know this effect from color - but just after years - and not with every emulsion.
Strange complication with Pan F .

Hmm ... graduation ceremony. Get fresh film, experiment some other time.

I have never experienced it myself as I usually process film within a couple of weeks of shooting. I also haven;t used Pan F or Pan F+ much, and not for about 10 years....but Ilford do advise specifically for Pan F+ that it must be processed within 90 days of shooting. There is something about this specific film which is different to all others.

But it just affects the latent image. As long as you process it quickly, afterwards it's just as stable as anything. I have negatives of Pan F and Pan F+ from the 80s, 90s and 2000's which are perfect.

Yes indeed Agulliver that should be the reason - so we can't notice the probems
Ilford warned about with Pan F.
I shoot many of PanF - never notice that
special latent image problem.
But I must say when I shoot bw I am so
impatient with results from shooting - I develope bw within 1 hour when I am back home again.
C-41 takes several days,often weeks.
I got this problem with one c-41 film (the only one ever) I totaly forgot it in a camera wich I had not often in use.
Half of the film shoes this phenomenon
(exposures 2,5 years old) the new exposures to the rest of the film were
Ok .
The old exposures were rather grainy and with little highlights over the whole pictures like snow and with less color saturation but without color crossings.
The other exposures were relative normal.
So this should be a latent exposure problem with C41.

with regards

Ilford acknowledges the problem exists for Pan F Plus. This is evidenced by the lighter than normal frame numbers.

If you wish to use Tech Pan for continuous tone negatives you must use a special developer to tame its contrast. There are about a dozen or so that I have counted. I would recommend H&W Control developer or Perfection XR-1 in that order. You will have to mix your own as neither one is commercially available anymore. Formulas are available on the net. Kodak used to make such a special developer but it too has been discontinued.

Indeed, standard B&W developers CAN be used. Start with rating TP at the same speed you rate Pan F+. Then try developing for about half to two-thirds the time you process Pan F+. It works well. - David Lyga

Yes Gerald there are indeed so much more parameters wich spoke much again
to use this special "wrong film" for a
gratuation ceremony tomorrow that my idea at the beginning of reading this thread was : "This should be a joke"
But meanwhile I noticed the OP understood : The idea to use this film was bad.
But to become familiar with this sort of
bw film in general (outside a wedding in 2 hours) ...is very good from my point of view.

I ended up using my trusty HP5+. I havent processed yet, but I got some amazing shots from the front row (It pays to have a last name with 'B'). At the very end of the roll, I turned around and all to be seen were green and white caps at all sorts of angles. There's always that one killer frame that burns into your mind's eye.

Agree here!

ROFL!

OP
if/when you decide to try your tech pan film
http://stores.photoformulary.com/td-3-techpan-developer/
is a mix yourself kit for something like the olde tech pan developer ..
ive never used techpan at pictorial speeds, i always used it at iso 200
and developed it in print developer to get high contrast negatives.
works great ~ ( i still have a roll of 35mm and a box or 2 of 4x5 i plan on developing the same way
or maybe split between print developer and coffee developer )
good luck !
