Kodak Australia Helpful

Left a message on the Kodak site U.S. asking the difference between 5219 (Vision3 500T, http://motion.kodak.com/US/en/motion/Products/Production/Color_Negative_Films/5219.htm) and 5230 (500T, http://motion.kodak.com/AU/en/motion/Products/Production/Color_Negative_Films/5230.htm) as it was newly listed with a newer data sheet.

Received a phone call from a Kodak Australia rep (Fuji Australia last year or the year before I had to chase down numbers which most were no longer working it seemed..) explaining that 5230 is basically Vision2 (iirc) and lower cost and aimed for TV dramas etc etc. with a more limited format size and length range. He was quite helpful and enthusiastic

5219 is still the latest and greatest 500T. It comes in 100ft spools.. so it's ready to bulk load, so I dont have to buy a 400ft core and rewind by hand into a bulk loader.. which takes some damn time last time I tried.

50D comes in a 200 ft core at the smallest size.. which isn't too bad, I'd like to try that too.

And also 1000ft of 65mm.. to trim down into my saved up 120 spools and paper.

Infrared Sensitisation of Film

So I have some Tri-X (Arista  Premium 400) loaded in a patterson tank I presoaked in water, then soaked in a pigment that has a certain amount of IR absorption.

Now the film is drying in the tank and will be re-loaded into a reloadable 35mm canister.

Hopefully there'll be some pigment adjacent to the silver halide, and hopefully the pigment will be able to transfer energy to it.

I'll be shooting it with an R72 filter, focussed visually on a ruler for test shots, looking for a focus shift on the ruler.

Things to try

Been in Melb for 6 weeks now...


Got a few things to try... pull-processing C-41 film, which I've already done in Rodinal and re-developed to colour before.. though that was 14 stop pull... good for daytime long exposure with no filters.

Got some old ISO 400 film that seems a bit crap and foggy at 400... though I did accidentally overdevelop it. Anyway, expose it at EI 50 and develop for 2 min 45 sec is the plan to see how it comes out.

Some bigger pulls with shorter times or C-41 with a 1+1 or 1+2 dilution and EI 12 and slower just to have a play.

Need to find some HCl from a pool shop to finish my concentrated 2 part colour negative developer.


Also got a roll of Rollei Pan 25 to test out.. not sure what to actually use it on though is the problem.



I want to try some Ektar 100 in 35mm lab-developed, and developed 'normally' (EI 100) in my concentrated developer (1+1+50), and pulled to EI 25 (1+1+100), with 8000 dpi Flextight 848 scans - just to ascertain differences.


The unbranded 400 ISO C-41 film shot @ EI 400, developed 3 min 45 sec accidentally and not agitated much (2 stop accidental push, was very dense and crappy), developed in Kodak Flexicolor at home, colour corrected (since it's C-41, posting orange negatives would be kinda odd).

16mm Motion Picture Film Developing Tank Mk1 aka "Missile Launcher"


Okay so the first developing tank is completed, it has numerous problems in operation, though isnt expensive to make, is a pain in the arse to actually use, I have already learned a lot and have a number of refinements for the heliacal-spiral type, though I'm 'putting my money' on a simple 2D spiral type.

Ultimately I want to construct something that has semi-automatic loading of up to 1000 ft in lengths in both 16mm and 35mm formats, which I have a few ideas for the future for.

Anyway, I've posted a video on vimeo detailing on putting this first version together, I will post chemistry mixing for ECN-2 and other videos in the future, such as other tank versions, and actually processing ECN-2 film, and B&W motion picture reversal stock.

Video journal of the "missile launcher" (since it likes to launch the inner tube like a missile if you dont tape the end cap on when using it).

This shows construction of the first 16mm ~100ft I built (ended up being 86.5ft in this one).

There are problems with this design I didn't know about or think of until I went to use it.

This design takes a long time to construct, is very difficult to load.

I would also recommend if using the heliacal-spiral type like this desig of mine, to have the spiral track cut into a tube (perhaps a wooden solid cylinder?) about 0.5cm+ deep so the film can be crank-wound on.

Currently, at the moment I recommend a 2D spiral type on a base board that gets placed into a bath, a spiral may seem hard to make, but you can do it with vertical rods (nails, dowel, otherwise, etc) rather than two tracks at bottom and top like a 35mm/120 roll hand processing tank for still film.

If your film needs to touch against something (such as the rod 2D spiral type or rack processor, or this tank in the video) wind it on so the emulsion side is not touching anything, then it is perfectly fine.

I'll make a new tank and show a video, as well as mixing up useable formula for processing ECN-2 at some point.

I'll be scaling up my final design when I find the perfect design after building enough 100ft tanks for 400ft and 1000ft and 35mm as well.
