Color images from B&W film...

These are amazing, @Andrew Keedle, especially the large format 7x17" bluebells.
 

The Maniac Mansion is around the corner, el Tentacle.

 
I gave it a try using my not-so-accurate red/blue/green lens filters held in front of the lens (not the right size for the lens).



It would be more fun if the assembly didn't have to happen on a computer....
 
Anyone who has done three colour carbon or even used a fair bit of masking in the darkroom will know that registration is certainly possible, even if one is doing so by eye.

How would that be done though, it’s clearly possible but how so, would the negatives be aligned under a loupe and then have a registration hole punched for alignment in the enlarger or is there something else?
 
Epiphyllum oxypetalum. Normally, the flower blooms at night and wilts by morning, but this one endured long enough for me to take a few daylight photos. Since I mainly use B&W, I took full advantage to make a trichrome color image.

Nikon FM2n, AI Nikkor 50mm f/1.8S, Kentmere Pan 400, developed in LegacyPro L110 at 1:31 for 5.5 minutes. Three individual black and white frames shot through Tiffen #25 Red, #58 Green, and #47 Blue filters, respectively, then combined using GIMP to create a trichrome color image.

Beautiful!!!
 

Accidentally around here but I`m gratefull with you guys and with this amazing thread. Superb results. Let me ask you a dummy question: Have you tried this process with X ray film ? Guess it`s possible but you would have just 2 channels, right? I´ll get my filters asap and to try this !

I'm still having a lot of fun with this process. You never know exactly what you'll get. The sweet spot for me is with MF or LF pinhole cameras and Ilford FP4. With the 3 stop filters it gives long enough exposures to capture the moving elements in a scene to induce some wacky colours

Just because I wanted to have a craic. I couldn't find/afford the correct filters, so just used some cheap eBay Cokin knock offs. Like a poster above, I simply held the filters in front of the lens. Not because I couldn't fit them to the lens, but because they're a tad tight in the holder and swapping them out between frames would likely have moved the camera.
While I do have a colour enlarger, I don't have the paper and chemicals to print colour. So, these are a quick Photoshop assembly.

You'd have to calibrate your workflow to get such separation negatives to print well onto RA4 paper. Frankly, I wouldn't bother with it. The results from the kind of digital assembly you've been making are great! Those should be compelling enough for anyone
 
There is something special about the colour achieved with this method.
Can anyone take a stab at explaining why exactly that is?
Is it the additive nature? Is it the relative steep/peaky nature of the filters?

I was thinking the same thing. When the registration is 100% accurate, and the filtration and light are good, it seems like this process generates a more realistic reproduction of colours. Perhaps "realistic" is not exactly the right word - because the photos retain their distinctive character even if the colours are not faithful.
