clip: kodachrome processed as black and white

[maprice123]

sorry about the overly tight closeup. I put camera on tripod, set focus, then marched out to film myself without checking the zoom :oops:

Did not clean dirt/hair nor try to sponge off the carbon black before doing a quicky telecine on the Tobin.

Mouth is jabbering because it was sound film (no sound in transfer)

The footage projects nicely, but is orange tinted. Nice detail with surprising lack of grain. Telecined footage gray-scaled in Vdub prior to uploading. No other manipulation.

Here, here!

Great effort!

Hi maprice, good effort....

How much is the average cost you spend to process one cart at home?

And anyone know how much the commercial labs will charge for processing Kodachrome as B/W?

[Mana]

Very cool! I kinda liked the tight close up, more interesting than your normal head and shoulder shot.

And I was just about to use some old Kodachrome to practice loading my spiral tank. After watching your clip, maybe I'll just try some leader.

[camera8mm]

you don't really say if you processed this yourself using what process or paid someone to do it.

[maprice123]

camera8mm,

Yes, I processed it at home in a lomo tank.

I forgot to mention that on the vimeo link.

Winbert,

It is difficult to arrive at a per-cartridge cost, because I don't recall the costs for the chemicals. It probably adds up to a couple of dollars per cartridge when you consider consumables, only:

I got a good deal on ebay at some point for a dozen bags of dry D-19 (any high contrast film or paper developer will work, even dektol), a great deal at some other time on fixer. Same with clearing agent (just purchase some sodium sulfite cheap off of ebay). Bought potassium dichromate on ebay, also. And sulfuric acid from hardware store (car battery solution). Decent lomo tanks out of old USSR still go for under $200usd on ebay.

The higher cost part would be the testing and care that you would have to take if you were developing somebody else's film, so I understand why
the commercial houses charge a lot of money for these boutique services. A commercial house would not want to idle a productive ecn or e-6 line for temporary changes in order to accommodate a 10-cartridge run of old kchrome.

Awesome. I thought I'd rushed all mine off to Dwayne's by the deadline, but realized I had the most important roll in my Nizo at the shop, so this might be the way to go. I assume the sound magnet isn't affected by the D-19. Great job. Looks pretty sharp too. which camera did you use?

I noticed the best exposure was overexposed for both the close up and the background shot. Does this mean that when using Kodachrome to be processed as B/W you should over expose by 2 stops? Can this be compensated for by increasing developing times instead of manually setting the f/stop.

J.S.

[mr8mm]

How would removing carbon black improve the results? What I am getting at is background dark because the carbon black has not been removed or is the background dark because the film is underexposed?

J.S.

[maprice123]

J.S.,

Thanks for checking out the clip.

I think nearly all the carbon came off during the processing, I just hoped people would forgive me for the bits that I did not sponge off.

The first developer came out of the lomo without any discoloration, but the first rinse with water after the first developer (and before the bleach step) came out pretty jet black. After that, the solutions all came out of the lomo pretty much unchanged with regard to color.

I re-projected the film the other night, and the close up actually looked close to right-on for exposure. I was standing against a very dark background (deep shadow behind me). But when projected, I could see detail behind me in the pictures.

At this point, at least with the sankyo that I used, 2-to-3 stops of overexposure seems about right. Like you mentioned, I bet that one could underexpose less and compensate with more development time. I was following the general advice given here:

http://www.ralphdickinson.com/process_s ... hrome.html

I had noticed when experimenting with some fresh (2007 expiration) 35mm kodachrome 64 black and white reversal processing, that +1.5 stops was not enough exposure.

I'd also note that Martin B. gives some excellent advice at:

http://www.cinematography.com/index.php?showtopic=48841

I followed his advice for processing kchrome as a b&w negative, and it works pretty darn well.

[maprice123]

Another try with kodachrome as black and white reversal.
Had a tripod 3 feet away and did not have the sense to put the camera on it - sorry about the shake:
