Uneven development with JandC 100 sheet film. Anyone else?

[mb81]

I am and 8x10 shooter and about about 2 years ago I started shooting with

JandC 400. I found this film to be incredible. Honestly up to par with Tri-

X, for half the price! The box was labeled ADOX.

Now, several months ago, I decided to try out their (JandC) 100 ISO film due

to the super low price of $16.99 for 25 sheets. I read a lot about pinholes

and uneven coating, but never anything about uneven development problems.

Now, I know in most cases this is the photographers fault, but I have never

had this problem with any other film, Not even the JandC 400.

All sheets were tray processed, and it seems that in the dense areas of EVERY

negative (roughly 100 sheets) there is uneven development. I keep wanting to

blame my technique, but it doesnt make sense that this is the only film I've

had this problem with.

 

So, my questions are, Has anyone else had this problem? and Who is the

manufacturer of this film? (so i know what not to buy). Thanks for all

comments.

Do you know of www.apug.org? You might pose this question over there.

I would contact John at J and C directly about the problem. He just got back from photokina so his email is backlogged, but he is very good about responding to quality problems with his products.

You could try and process a sheet of another proven film at the same time with the same tecknique and see if it is your processing.. or even if maybe your chems went wicked for some reason.... Shooting 8X10 is never cheap and There do seem to be growing pains with the ADOX name change over... you can still get the origional Forte 8x10 at Freestyle.

Sorry I ment Efke that is the NEW ADOX Forte is the smaller formats that are sold under the J&C classic name.... EFke is a great film I love the 100 with a passion in 35mm it to me is almost a direct replacement when processed in Rodinal 1-100 for Apx 25

I use Efke 100 5X7, and believe me you HAVE TO presoak for even development. Usually 1 min. is sufficent, but 2 min. is safer.

When did you get J and C sheet film? I have been looking for this stuff in 4X5 since Spring. I was told that they would have it re-stocked in October but it is not there in 4X5 or 120.

Thanks for the answers guys. I found two problems. The first is that yes, it Must have a presoak. With most of the 320 and 400iso films that I use it is not needed. Second is that I found out that this film is formulated for use mainly with pyro. I was told by another user of this film in 8x10 that he had the same problem until he started using pyro with it. Now he has no problems.

 

As far as getting the stuff, I never had any problems getting it. Just ordered it off their website. But keep in mind that 8x10 is in much less demand than 4x5 and 120, so that may be why it has been out of stock in those sizes.
