I'm not trying to be critical but why not just use color negative film and paper? It's designed to do this. What's the advantage to making photo paper do things it was never designed to do?
@MatMarrash2 жыл бұрын
Michael this is a great question! In terms of 8x10 the appeal isn't much since there's a lot of effort. However in ULF sizes, the pricing is significantly better for shooting on paper instead of buying custom cut Kodak color negative films. Once you hit 16x20" the cost per shot is < 5% of using film.
@CM-cb2km2 жыл бұрын
Really great video! I've been trying this process on and off for a year now, and like you say, it's about filtration and light. It's fun when you get a good shot, and so frustrating when you mess up. My current ratio is about 1 good to 10 mess up's. So, I'm still learning the process. I got 5x7 Fuji Crystal sheets for my 5x7 camera that are quite cheap.

Hey Bernard, that Calumet C1 really is a monster! I think for the 8x10 he's got on there a triple convertible f/6.8, can't remember the series or FL. Due to the heavy filtration and bellows factor, most shots were close to wide open. Cheers!

The gossen digi pro f2 will meter multiple flashes -- it tells you how many flash bursts you'll need for a desired exposure. Obviously only good for still life unless there's a high speed flash unit out there I don't know about?

Mat, is this simmilar to the Slide film process?, or more akin to "cross processing", that of doing B&W film in colour chemistry, as these are what you are doing, and also what about the Ilford positive paper, does working with this make the process easier, as opposed to the RA-4, if this is the output you are after.
@SilntObsvr2 жыл бұрын
I wish I could make it to the RA-4 reversal session -- just to watch or assist (and learn, of course). But I do get to gloat a little -- my LomoGraflok came in the day before Thanksgiving, and the fresh film I ordered came the day after. Due to limited play time I've only shot about 3/4 of the first pack, and I'm having issues with the Graflok conversion back I mounted on my Anniversary Speed Graphic, but I'm completely confident everything will be right when I can get my Graphic View II out with its original Graflok back (and I'm considering how to put a set of its clips on my Speed Graphic to use that clip-on reversing back with the more portable, rangefinder-equipped camera). FWIW, the production LomoGraflok is very professional looking, cleanly designed and fairly robust -- mine slipped out of my hand and fell a couple feet onto my kitchen floor and doesn't even show a mark. I'm still getting used to the extremely narrow exposure latitude of the Instax material, but when it's right, it's *spectacular*. I know the reason why all they make is the 2(ish) inch high in three widths -- so they only need one coating and pod filling/attaching machine, and then cut and seal to the various lengths -- but I really, really wish they'd make this stuff in larger print sizes. Even 4(ish) inch high, to give 4x4 and 4x6 prints would blow away any integral instant Polaroid ever offered (and, at least for color, I think it would compete with FP-100C). They'd still be able to sell their own camera (plastic lens, auto exposure and manual focus like the existing Mini cameras) for around $100, and that would give the hackers of the world a start for putting those bigger prints behind a 4x5 camera...
@MatMarrash2 жыл бұрын
Fingers crossed the Graflok conversion and happy to hear you've been enjoying the instant back! "Fuji-roids" are awesome when the exposure is spot-on and their neutral color palatte is so awesome to watch emerge in the print. I would cry tears of joy for a film integral and larger than Instax Wide!

@bernardpanier82312 жыл бұрын
Thank you for all the insights. Love it. I gave it a good try and had poor results and am not sure where the problem is. First I metered the scene (at ISO6) and got an EV of 13, Went to 12 to have ISO3, subtracted 3 stops/EV to compensate the filterpack giving EV9 (a 1sec exposure at f5,6). The result U had using a fresh B/W developer (90seconds), stop and rinse and exposing it for +60seconds was very very light (tests with longer and shorter exposure gave similar results). Developing it in RA-4 dev resulted in a black paper :-(. The light I used to expose the scene were LED lights. I'm not sure where to start looking for better results.
@MatMarrash2 жыл бұрын
Hey Bernard thanks for sharing your experiences and for the question! From what you've posted on metering that looks to be alright, and the only thing that could be causing a black print is too little time in the B&W developer. When you hit the lights in the water wash, the B&W negative should look like a dense paper negative.
