Tri-filter color images from B&W negatives

[blue4130]

I couldn't find a thread about this, so here is my 4x5 attempt at stacking three filtered b&w shots in Photoshop. My Red Green and Blue filters are not calibrated to any standard, so the colors are a bit off. I also used a $2 industrial achromat that "flavors" the colors a bit. Highly uncorrected it is. Overall, its a fun way to get color.

The technique predates technicolor by more than 30 years from my research. I know if it being used in at least 1890, likely earlier that that also.

Here's an early camera that took three shots simultaneously.

Vance,

That's your first attempt? Congratulations, it's a wonderful image.

For better or for worse, here's a link to web pages I've prepared on the subject of tri-color photography. http://vintagephoto.tv/color1.shtml

I've been told my guide to assembling separations in Photoshop is a bit tedious... but nonetheless the method and variations on the theme work for me.

And here is one of my images. I enjoy taking the separations with a time delay so that the final image presents the passage of time in a colorful way.

Have you tried a Devin Tri-Color camera? I've never laid hands on one, but they look very interesting.

Your uncorrected method produced a very nice color image.

I really like that idea and it works perfectly for the skate part.

This thread has inspired me to give it a try. I've had the filters for a while but for some reason just haven't gotten around to doing it.

I have a Devin but the pellicles are damaged, so it's not useable. On the other hand, I have used my 4x5 Curtis tri-color camera with success.

Am in admiration of your imagery. Attempted the same with a 120 6x7 SLR many years ago and had all kinds of problems... film registry my biggest problem. FYI: moving subjects turned into my most interesting imagery.

Apologies if some of y'all have seen this. Have really only gotten one good result doing this. Long-term, I'd like to do more of these, but the conditions have to be just right, and that is fairly uncommon. And I don't always bring the right stuff.



Oh yeah, and this one, but it's a 6x9 image so...well still applicable:
