Caffenol-C-H second test roll TMY-2

Second roll of TMAX400. This time upped the potassium bromide to the Caffenol.blogspot.com recommended base level. TMAX100 seems to require no bromide at all to keep the haze in check, TMAX400 however is another matter. Even with 1g/l this second go wasn´t without quite a bit of haze, though better than the first effort. Made for an easier time in post-processing. When I next get hold of TMAX400, I´ll be upping the bromide a bit more, and adding somewhat to the development times as it to a certain degree arrests development.

Autumn at its dreariest does have its own allure. Kowa Super 66 w/85mmf2.8, TMAX400 EI 320, Caffenol-C-H @ 13m45s 20C:

Caffenol-C-H first test roll TMY-2

After, at least my my standards, finding a successful recipe for TMAX 100, I thought I´d have a go at TMAX 400 (TMY-2). This seems to be a different emulsion altogether. I looked up whatever I could find on TMY-2 in Caffenol. The caffenol blogspot had some examples of course, but these were done in Caffenol-C-L, not C-H. Stand development, and not agitated etc. So were to start? Well I took the same solution as before, C-C-H with reduced potassium bromide levels, and my experience with development times TMAX 100 and guessed at 15 minutes @ 20C. I shot a roll of 120 film at EI 200, 400, 800 and 1600. Something or other didn´t quite fit. Exposures EI 200 to 800 more or less came out equal. Flat, rather flatter than TMAX 100. The negatives also displayed a lot more haze than with TMAX 100 (were haze is practically non-existent). The results don´t really merit being put up here, apart from one shot which came out rather nicely. At least the whole roll wasn´t a disaster:

TMY-2 EI 800 in Caffenol-C-H 0.4g/l potassium bromide 15min @ 20C

Looking at the negatives I wouldn´t say they were underdeveloped. I will develop my next roll with 1g/l of bromide and see how that goes. I´ll reduce the development time a couple of minutes too.

I´d been pondering over what to do with handle for a while when I came over flickr member "adbieber" creations. A master of camera building and modification. His Nimslo quad lens camera conversion to a 135 film panoramic camera is one such masterpiece: adbiber´s Nimslo panoramic flickr set

I took inspiration from the handle and adapted the design for my purposes. It turned out like this:

And finally I added an accessory shoe for a rangefinder, and added a spirit level:

I´ve no desire to modify it more. It works as intended, and even if rather large in size, weighs no more than 2.3kg including roll film back. For a 4x5 camera, I don´t think thats too bad. Instead I´ll be making another camera over the long Norwegian winter. A few shots with the camera as it now stands:

Two images from the first two rolls of film. Unfortunately most images were ruined due to a light leak. I´ve since found out the left hand side of the roll film back does not mate perfectly with the Graflok back letting in light. Need to add som velvet or foam to get it right.

Anyhow, these are shot on TMY-2 and TMX respectively. (click for bigger image)
