250D, Revisited

Brief pause on the vacay photos for the moment–Here are some pictures of some cute girls.

This is self-rolled Kodak 250D, but treated with some right-proper “ECN-2 Prebath” that I ordered from Argentix.ca

It is interesting stuff–nothing happens when you first pour it out (30-60 second rinse before C-41 development) but the Remjet layer subsequently dissolves away with repeated rinses.  (I needed 8 rinses with agitation before the water ran clear).  I have been looking for something like this for quite some time.  There are proper “recipes” out there, but buying the necessary chemicals in bulk is prohibitive (not to mention “suspicious” lol…)

Anyway, it is finally available commercially in small amounts.

While there is the *tiniest* bit of scant surface residue on occasional frames, it wipes away easily with a lens tissue once dry, and before scanning.  The removal is fairly complete, with fairly little effort.

The advantage here is that you don’t need to use SUPER HOT baking soda rinses, and do not get the reticulations or changes in the grain structure of the film.  Furthermore, your chemicals and equipment stay cleaner.

I think I may see more 250D in my future.

    Nice results! 250D has an incredibly pleasing grain structure. It’s similar to Portra 400, but I think it looks better. I know Portra 400 and 160 were both “upgraded” with Vision3 tech some time ago. Interestingly, I like the look of Portra 800 more than the other two, despite it not receiving the same update. I also like 500T the most out of the Vision3 stocks. Maybe I just like grain…

      Hi “P”

      Totally agreed. Unfortunately home processing non-Cinestill 50, 250, or 500 ISO cinema film required manual removal of the Remjet backing with extra-hot sodium bicarbonate. In the process, the microscopic grain structure was altered slightly. (You can see some of my earlier work for examples).

      The native grain structure visible here is actually quite pleasing.

        Yeah, that pesky remjet is a real pain. I would personally never do the high temperature pre-bath methods for the reason you mentioned. It’s too much effort to go through the hassle required to shoot and develop ECN-2 film if at the end of it all you’ve damaged the emulsion. Yes, the native grain structure in your images above is very pleasing. The transition from light to dark in the out-of-focus area in the first photo shows clearly just how nice the grain is.

        Take care!

    That shot of Baby J is just too much! Peter is right – there’s some magic going on there. Print it, then hang it. 😉

    This film really does look damned good, too.
