I usually don't like to speculate before testing, but let's pretend it is the developer. I know a lot of people will say choice of developer is simply a matter of taste. I don't think I'm to the point of being able to differentiate the two devs I've used so far: kodak d76 for about 8 years (35mm film), then recently I recently switched to ilfosol s for 4x5. I liked the ilfosol b/c it was easy to mix... but if its shelf life isn't very good unless it's in a compressed bottle... what dev would you folks recommend?

Am I hijacking my own thread here?

I won't be able to test the film until tonight... maybe tomorrow... but I will definitely leave feedback as to what I find out.

Thanks again!!
