Well I don't know if anyone will be interested in this post on my blog, but in it I explain how to get colour images from ordinary B&W film

Colour from Tri-x

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

That is interesting, I had heard of Sergi Prokudin-Gorskii but the thought never crossed my mind one could try that with B&W film and combine in PS. The result looks quite good.

 

Alternatively you could do it the old fashioned way by hand coloring.... sure is a lot easier in PS as well

Done the below a few years back when I had some spare time

Thanks Peter, I have had a second try:

 

I think that with a Tripod you could get perfect register, but I like in the cityscape above how the people are recorded as colour ghosts in the opposite colour of the filter used.

I think I'll try a landscape on Pan F on a bright wind-less day next....

This is an interesting process, Mark. I think you deserve applause for the tenacity to wiggle out the details. OTOH, I find this a schoolbook exercise to prove a point. Nice job, but it isn't anything I would be tempted to try

Hi John

There is a method behind my madness, rather than proving a point– I can get colour from B&W. This is a genuine process from 100 years ago:

Early colour

 

The reason for this 'experiment' is that much more dynamic range and control can be gotten from it than normal colour process.

Also you want tech pan in colour or Delta 3200?

For certain types of photo it is possible

Edwind Land (Polaroid) did this many years ago and the methodology was widely known back then.

I did this in 1961 in my junior year in High School but since thier were no digital scanners available, I used B&W reversal film. The images were simply projected with two different projectors and one color filter, red if I remember correctly.

Of course using neg film and the digital scanners of today is much easier!

Of course just using a digital camera is much much easier!-Dick

Richard the first time this process was used was in 1861 by James Clerk Maxwell, his modus was the same as people who followed later, and the inspiration behind early colour processes like Dufay colour and Autochrome which are relatively recent 1907 and 1908 respectively.

 

I realise that it would be easier to use digital ie digital scanning back (I did a dry run with split channel 20D images) but I really wanted to try colour from B&W especially to see what i can do with very fast emulsions like Delta 3200 and TMZ.

 

Really I quite like the artifacts caused by movement between exposures, and as far as I know there are very few using this process with PSCS.

So I thought I'd give it a go:)

Apathetic I'm not
