I have in the past taken 3 B&W film photos through R G B filters and combined them in Photoshop to create a color image. I was wondering if anyone has tried this twist:

- Capture one image in B&W with your view camera, and then capture the color image with a DSLR. Strip away the Luminosity channel leaving the A & B color channels to be interpolated to the same size as the film and combine to make the color image.

I'm thinking about a couple of things:

1) Film and processing cost savings
2) Easier processing of color
3) Color channels don't require as high resolution
4) B&W film far outresolves normal color emulsions and as such, the luminosity channel from the B&W scan will provide more detail than a straight scan of color film

Because of the fact that the eye obtains most of it's resolution impression from the luminosity data, the color data can be relatively low in rez and still provide the necessary information.

I'm not talking about using a low end DSLR, but something in the 10 to 15 megapixel range. This should provide good enough color rez and allow greater dynamic range on the color channels.

Any thoughts?
