There are other filters for BW photography other than the #25 red. If you 
want to lighten a specific colour then you use a filter of the same colour, 
in this case green. This may not darken the sky as much as desired. A 
yellow filter should provide something of a compromise.

Technically speaking a red filter on IR film also darkens greens, it's only 
the extra reflection of IR that makes foliage lighter which is a completely 
different story. It's then a case of using the right filter with the right 
film to get what ever effect you're after, whether it's IR or not.

I also prefer the panchromatic films with extended red sensitivity although 
I usually use them unfiltered for a very natural looking tonal range.

Cheers
