B&W On A DSLR

[Joseph Tainter]

Let's say you shoot on a Pentax DSLR, with the intention at the start of 
converting the image to grayscale. You shoot with a red or yellow or 
green filter, with the final B&W image in mind. One shoots in Raw. After 
converting to TIFF, then converting to grayscale, will the effect of, 
say, a red filter still be present in the image? Or will the white 
balance just correct for it at the time the image is shot?

If the answer is that the effect of the filter will be corrected by 
white balance, then much of my interest in ever doing digital B&W 
photography disappears.
