Color photography with black and white film

[Drew Wiley]

Corran - an X1 would be useless for this purpose. It lets way too much of the other
primary colors through.

Just now saw this. Thanks, I will look for a cheap #58.

My first attempt. Stupidly chose a subject with subtle colours. It's not quite right. The timber background was a real chocolate brown, and my daughters trashed dancing shoes a dirty soft pink with what I remember were lime green reflections off some off the little hex sparkly bits....

But still nice! Keep posting. This is great.

I really think that has an excellent feel to it Jon!

I haven't seen it mentioned and have been through the thread twice. What values are people using for their color layers? The french translation link posted a few pages back gave me his channel mixer values for RGB. But I saw Sandy mention magenta, yellow, and cyan too. Is there a preferred way to overlay the colors? I tried this on a digital color image of mine and the result was fairly encouraging. I may have to give it a try with some black and white negatives. Makes me a bit less concerned about the future of color film. Obviously though movement might be a problem.

Hi All,

I don't know if this topic still holds interest. Everything about photography morphs so fast. But, even if tricolor separation with film isn't currently of wide interest, I can hope that it resonates with an individual or two.

As some of you may know (gawd know I talk about it enough ) I work with handmade silver gelatin emulsions -- first colorblind, then ortho, and now panchromatic. Adding pan to the first two, in a suite of three emulsion types, allows for separations as done back in the day for color carbon, etc. Anyway, here's the info. I'd love to see a chemical color photography artist take a swing at emulsion making.

The info about pan starts here, but there is more info leading up to it on the previous two pages. http://www.thelightfarm.com/cgi-bin/...tent=02Sep2013

Hello guys!

Your thread here inspired me hugely, even if it happened only with some delay.
Some weeks ago I finally bought the right filters, exposed, developed and scanned the negatives, and... don´t know what to do next.
It´s quite embarrassing but I have no clue how to merge the three negs in Photoshop.
I´ve tried hard in the last many days but find no way to do it.
Could one of you tell me step by step (please!) how I can create a color image on a computer screen?
I´m sorry, I´m probably too analogue to solve this problem on my own...
I will really appreciate your help on that.

Kind regards,
Marcin

hi marcin

http://photo-utopia.blogspot.com/200...om-b-film.html

it explains how to do it...

i have been taking black and white prints and making color separations in ps
and adding my own cmy levels and merging them in an open file's color channels
and getting great results.

have fun!

Hi John,

thank you for your quick answer.

I´ve been trying to follow the instructions you found on PhotoUtopia.
Unfortunately, even if I adjust the size of all three pictures the field "Merge Channels" remains inactive.

What I could do (and did) was "Split Channels", after which "Merge Channels" got activated.
But even then, that was it and I couldn´t procede to make a color image...

A few attempts later, with a little help from my girlfriend...



Now, it looks like color!
I´m very happy with this result!
:-)

The problem (hopefully the last one) is that my scanner doesn´t crop half-frame negatives as it should.
The scans therefore have to be adjusted because at the moment the three layers simply don´t fit exactly, as you can see.
What is the best way to do this?
:-)

You're on your way! Here's the site with the merging technique I use: http://www.vintagephoto.tv/photoshop_assembly.shtml It includes all steps for moving and merging the layers seamlessly. It's actually a lot simpler than the number of steps makes it look like in the tutorial. It's just that he's has spelled out every little detail (always a good thing ).
