Has anything changed with HP5 emulsion since run with dates of 2007?
I had 2 OCT 2007 boxes and 2 boxes of Dec 2007. I tested all the film when I shot it with a densitometer and it was rated at 200 and the dev time of the different emulsion were within 10 seconds different in dev time.
Now I opened a Sept 2008 box and figured looks like they fixed the problems with inconsistent batches. So I went out and shot using the same index as stated above and dev as normal from the other two emulsions. Then a problem happened. The negs were no where near close. So I started testing using the densitometer.
The film speed is sitting around 100 ISO and this is supposed to be a 400 speed film. What the heck is going on? I have only had this problem with one other film and I found out that it was miss packaged film. Has any one had any problem with HP5 that is emulsion September 2008?
With shooting 8x10 this is really unacceptable especially with the cost of the stuff and I only have 25 sheets in a box to test with. They can raise their price but at this point I am gone I cannot afford to have to test every single different emulsion. a 1/3 stop here or there fine but this is over a stop and at $3 a sheet no one can afford it.
What changed?
I have shot hundreds of negs in HP5 in both 4x5 and 8x10 and I always test the exact same way and NEVER seen anything this bad before.
I really hate 100 speed film but at this rate Efke is looking better every day. 50 sheets for $105 bucks is much better than $80 for 25 for the film that will be close. Well 50 ISO for Efke to 100 for HP5 I will deal with Efke.
Geez....
