Specifically, Kodak 7291 Color Negative Film.  I see its process is ECN, not ECN-2.  Is the process significantly different?  

 

Of course, I realize this film is probably 20-30 years old.  Ignore that for now.  Assume fresh stock, what difference am I looking at?  Is it something the lab even needs to know about?

 

Thanks!

Yes very different , labs [ the few that survive] would not be able to run ECN now . Kodaks stock numbers are so confusing but i think 7291 was a ECN-2 process, cant remember for sure.

I am 99% sure it is ECN not ECN-2...

 

So, ECN-2 result would be bad?

The first ECN2 (high temperature) stock was 7247. The last ECN stock was 7254. 7291 was the successor to 7247 so definately ECN2. If you would process an ECN stock in ECN2 process the emulsion would not survive the 41.1°C temp of the developer.

Kodak sometimes recycles emulsion type numbers but that would be evident from the age of the label.

$T2eC16V,!)0E9s37GHCPBR9ZL+k0Cw~~60_57.JThis is why I am asking:

 

 

Even if it comes out crappy, I'm fine with that.  I just need to know if I can have it processed as ECN-2 without pissing off the lab.   :)

From what I can tell, this stock was available from 1983-1989.  So, that would mean it must be ECN-2, right?

Right,

 

I still remember receiving the first fresh rolls. It didn't have T-grain yet but had a much improved tonal range compared to 7247. Must be very fogged now.

For anyone concerned... I did get confirmation from a few labs that it is ECN-2 and they can process it... of course along with the usual "it will likely color shift and be fogged" disclaimer.  

 

But... I understand they have to say it.  Some people are not going to believe it or understand it.  Just like I find there are lots of people that don't understand why I don't care.  LOL

 

For example...

 

I just picked up some 7251 Ektachrome as well as part of the same purchase with the 7291.  Here is what I am hoping to see when I'm done:

 

 

I love this footage by Justin!  It's just fantastic looking.

Another from the same batch he used... I'm pretty sure it's the same 7251 I got... might be even older.

I dont know what part of the world you live in? But getting 7251 processed again could be a problem.

Processed as E-6 is easy and sufficient. VNF would be a whole different story.

I'm northeast USA near Boston.

send a clip test to Cinelab before shooting, just to know where you stand.
