Sounds a little beyond my knowledge so I'll probably just end up doing some tests.

I tried it out the other day by placing a yellow filter in front of my digital camera, metering, plugging that into the exposure calculation formula (13 minute exposure), and then took the photo with my pinhole camera. When I developed it the negative was VERY thin, there was hardly any detail there. I went back out, metered without the yellow filter, plugged it into the calculation and I ended up getting an exposure time of a little over 10 minutes and then took the photo without the filter. I develop that one and it turned out MUCH better.
