RCJets:

Use an orange (or red) filter and a polarizer. But bracket as you'll have a big filter factor.

In older versions of Photoshop there was no specific option to make B&W, what there was was an option to convert the color space to Grayscale. In newer PS version you can still do convert to Grayscale as well as a B&W option. No if a red filter is used the RGB channels of the image will be impoverished in green & blue, to the grayscale will come primarily from the red channel. A black rich in red will look different from a black rich in blue or green. In doing film B&W there are no RGB channels and only bits of precipitated silver. A question is - does a black which is rich in red add some kind of density character to the film.

This probably doesn't help much.

I have heard lots of discussion about whether it is good to use a red filter or not. It is true you can adjust the picture after the fact to get a Black & White look that you like. But in reality, that red filter is totally shifting the color the sensors see. The blue and green sensors are exposed to light that has less blue and green content and the red is overjoyed with the additional red that it sees. I suspect, but haven't actually confirmed that the contrast is going to be greater than what I can get without using the red filter and just adjusting after the fact. Perhaps someone can say for sure.

I do have all sorts of filters - red, orange, yellow, etc. They were of great use with film cameras when shooting black & white.

There's actually a disadvantage to shooting in B&W. Shooting in color allows for tonal adjustment by color-- more control over the final image.
