And of course, they had to create the processing capability as well - no other colour process was available to the market.The marketing people at Kodak decided that at least for the start the amateur moviemakers would be their aim. They were the people who got projection means.
When you sent your Kodachrome still films into Kodak to be processed, the first thing they did was splice them together with a whole bunch of other customer films - a mile of film all together, to which another mile of leader and another mile of trailer was added, and the entire three mile long roll was then fed into the motion picture roller transport processor to be developed all together at one time.

Is that what somebody like Horst P Horst would have shot his fashion color photos with.?When Kodachrome sheet film was available I always wondered how they processed it. From the marks I have seen, it looks like typical cleat holders in a dip and dunk machine, like used for C41 and E6. I suspect anyone who would know is long dead.
From literature at the time, the only sheet processing facilities were at Rochester and Hollywood.
MattKing is referring to the fact that the Kodachrome processing machinery was of the "continuous" type, which requires that the entire machine be threaded up in order to run. Thus the large amount of leader/trailer. Seems odd to someone used to home processing, but it was/is standard practice in high-volume applications. Things are done differently- when on an industrial scale.
I know, or rather i have always heard, it was a popular 16mm movie film.
Was Kodachrome used for 35mm movies also.?
Thank You
The only movie I ever made was shot on Super 8 Kodachrome. It was edited using a cutter and film cement. I was 15 at the time, and I vaguely remember it being awful!

It's a great thing in life Matt, to know your own limitations
For those intrepid tinkerers out there still trying to revive K-14, a thought. One of the trickiest parts of this process is the necessity for controlled flashing with colored lights, first from the front, then from the rear as part of the reversal step. This more than anything else makes the process awkward/unsuitable for tank-and-reel processing, tough it is no particular obstacle to machine processing. Suppose one did away with the reversal step altogether and processed it as a color negative? Several steps would be eliminated and color images would still be recoverable from old rolls, with the bonus that the film (save for remjet removal) could remain on the reel.
I've now built an Arduino controlled device using LEDs and the glass filters specified in the K14M Theory Guide, using the exposure levels in the Guide. This week I switched to using the couplers and colour developers from the 1938 Mannes & Godowsky patent, and the first developer from the 1972 Bent & Mowrey patent. Here's the scan of the Super 8 Kodachrome 40 that I processed last week, using these methods:
here's the process I used:
Modified K14 process
- 05:00 remjet removal bath
- 04:00 wash
- 04:00 First development
- 02:00 wash
- 05:00 remove film from Lomo spiral
- 05:00 remove remjet - 04:00 Red exposure
- 1000 micro watt seconds per square centimetre through Kopp 2403 filter, 5mm thick
- 03:00 Reload onto Lomo spiral
- 01:00 Add Cyan coupler to developer (on magnetic stirrer)
- 12:00 cyan developer bath 20°C (constant mild agitation)
- 03:00 wash - 05:00 remove film from Lomo spiral
- 05:00 Blue exposure
- 230 micro watt seconds per cm2 through Schott BG25 glass filter, 5mm thick - 03:00 reload onto Lomo spiral
- 01:00 add yellow coupler to developer
- 10:00 yellow development bath 20°C (constant mild agitation)
- 03:00 wash
- 08:00 White light exposure
- 01:00 Add magenta coupler to developer
- 05:00 Magenta development bath 20°C (constant mild agitation)
- 03:00 wash - 08:00 Ferricyanide bleach bath 24°C - 01:00 wash
- 06:00 sodium thiosulphate fixer bath 24°C
- 06:00 wash
- 01:00 stabiliser bath 24°C

No the initial development was B&W the colour flashing exposure wasthe reversal stage. the best explanation of Kodacrome was written by Viscount D.A Soencer in Colour Photography in Practice, I think Pitmans,. Spencer was actually a Director of Kodak Ltd here in the UK and worked with Kodak's Harrow Research facility, my copy is early but the book was updated and reprinted many times.
Some B&W eversal processes like Pathescope used variable 2nd exposure as a control. it's often forgotten that many of Kodaks vin technology came from the AHarrow research facility, T-grain films for example. But lets not forget that both Kodaks Rochester and Harrow Research facilities were for decades run by former Wraten and Wainwright emplyees who had been employed by GEK Mees.
A pointless post because it isn't going to happen. This has been chewed over time and time again and is frankly getting boring

It doesn't fail to hold water because it is completely pointless question and a waste of bandwidth, 'cos it ain't going to happen. Just to highlight that it is a resurgence of well chewed topic from the recent past and totally pointless . Ever heard of the phrase 'Let sleeping dogs lie'.Yet you clicked on the title regardless. Your statement fails to hold water.
