hello,
i would really appreciate it if anyone on this list can respond to my
question. i have just shot two cartridges of Tri x super 8 film, one is 7266 and
the other is 7278. is the handprocessing the same for both?
Thank you!

No.

IMPORTANT NOTICES
IMPORTANT NOTICE for those developing KODAK BLACK AND WHITE REVERSAL FILMS
(all formats)
As of October 1st, 2003 Eastman Kodak has introduced two new black and white
reversal films that are to replace the older Plus-X 7276 and Tri-X 7278
films. They are to be called Plus-X 7265 and Tri-X 7266. Kodak reformulated these
films to accomodate a new black and white reversal process that uses a new
environmentally safe bleach and a higher energy developer. The new R-10 bleach
does not use the metallic compounds that the older R-9 used, therefore
making it more environmentally friendly and less costly to dispose of. The new
developer/bleach combination allows Plus-X film to be exposed at 100 ASA.
In addition, the new Plus-X features increased sensitivity (100 ASA in
daylight) at what Kodak terms a slight grain penalty, while the new Tri-X features
finer grain for its 200 ASA (daylight) speed and lower contrast than its
older brother, 7278.
Kodak claims full cross compatibility - the older films can be developed
using the new chemical formulas, and the new films can be developed using the
old classic formulas. However, it is important to note that both the new and
old Plus-X films are to be exposed at 50 ASA (daylight) when being developed in
the old chemistry, and 100 ASA when developed in the new chemistry. There
is no change with the Tri-X films, as far as I am aware from Kodak's
information.
Most laboratories intend to switch to the new process on October 1st, 2003.
If you have Plus-X film that has been exposed at 50 ASA, and have not
processed it yet - either get it to a lab that still uses the old process, or
develop it yourself using the Kodak specifications below or any of the other
classic formulae on the net.
I have not tested these new films or process combinations, nor do I
currently have the new formulae (the Kodak D-94a developer and the R-10 bleach) - but
Kodak said that it would be releasing the formulas around December of 2003
on their webpage. The processing information I have on this webpage does not
yet reflect the new process. Check the _Kodak webpage_ (http://www.kodak.com/)
(cinematography section) and the _Kodak FAQ_
(http://www.kodak.com/US/en/motion/16mm/features/newBWFilmsQA.jhtml?id=0.2.20&lc=en) on these two new films
for more detailed information.
