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.

New Portra 400... overexposed 5 stops?? ISO 12.5??
Hmmm.
So on one of our photowalks in Melbourne city, I incident metered for the shade, as most of my subject as in the shade and wanted to optimise exposure for my subject, this is an extra +5 stops compared to a subject in the sunlit areas... yet it handled this mixed shade/sun combination beautifully, and flattened out the lighting contrast and did not get too dense, tones are reproduced beautifull for subjects both in shade and sun, it handles such a extreme harsh contrast condition wonderfully.. I have midtones for both!
The New Portra 400.. it has fine grain.. it is very sharp, it has wonderful saturation, and a ton of local contrast snap, very good skin tones.. it is high speed.. it is pushable.. it handles overexposure, it retains highlights, it can compensate high contrast with increased exposure without pull-processing.. if you had to have only 1 colour film, this would be it, forget Ektar, you can do everything with this.
If I was shooting for the sunlit area.. you would call this an EI of 12.5! This isn't a pull-process either, it is standard.
First 10 people in Australia to Like my services page, get free C-41 processing and web size scanning of a single roll of 35mm or 120, includes cross-processing and an pull/push you wish to have done.

Portra 400 pushed to 1600
New Portra 400 pushed to 1600.. that's 4 minutes 15 seconds in C-41 developer :)
This new film is beautiful and it handles excellent at 1600.. as long as you push it though!
Though there is invariably going to be a couple of times when a bit of underexposure will be introduced, so perhaps a push to 3200, but using an EI of 1600 for exposure would be best, or push to 1600 with an EI of 1250 or 1000 even better.
Portra 400 @ 1600

C-41 Infrared Test #1
C-41 Infrared Test #1
I figured just like with digital cameras, in a consumer product you can't remove all susceptibility outside the visible spectrum, just have several stops of difference in sensitivity.
R72 Filter used, +14.5 stops of 'filter compensation' to get this effect, or EI 0.017 from a ISO 400 film (I should mention this included 2 stops of reciprocity correction, but its just guess work at this point).
Exposure was f/2.8, 15 seconds, correct unfiltered exposure was f/11, 1/400th.
I was considered lowering the pH level of the C-41 developer to effectively underdevelop the reds, but the reds dont seem that dense as I suspect they would be, they seem quite godo, but the green and blue channels have a thin density range.
Needs more exposure, with a green and blue filter, would probably help a bit.
Defniately seems to be an IR effect their to my eyes.
Film was ISO 400 35mm cheap unknown brand film, unknown age.
Scanned with levels set on each colour channel to not have any clipping at all, then auto-levelled to provide a 'balanced' image (regardless of false colour) to see the effect.
Test #2 will include the colour filters and increased exposure.
A high contrast film may be much better for this, less expansion of green and blue would be needed, hence less grain contrast, and less shitty scanner noise, perhaps Velvia etc.
