I ordered some TRI-X from Calumet last week and was told that they were shipping only the new emulsion so I only ordered one box for a try. To my dismay, and delight, I recieved the old emulsion. Had I know that, I would have ordered more. I will complain.
I also order some HC110. The new bottle has frosty clear, instead of the opaque grey. When I poured it out, the color was lighter and it was thinner then the old bottle. The old bottle was only a few months old so age would have little effect.
As for the times, the first batch were slightly over developed and I had to shorten my times. I used 1/46 from concentrated, new time 7 minutes, old, 9 miniutes, agitation 10 secs/minute in HP Combi tanks.
This leads me to believe that the shorter HC110 times everybody is concerned about, is due to the developer, and not the new emulsion.
Kodak now recommends HC110 dil B for 3.75 minutes. It is interesting to note that the AA book, The Negative, in Appx 1 has test times for TRI-X in HC110 dil B at 4.25 mins, ASA 160, a 30 sec difference. Also, if you look at the Kodak development chart, it has essentially the same times for all other developers, with HC110 having the most drastic change.
Just some observations to pass along.
