if you use a tiffen 47B then you dont even need a channel swap. you just desaturate the yellow channel to get white foliage. Cheers Paul UK

Tiffen 47B may be a little "too blue," some sources recommend Tiffen 47 instead. It is currently my favorite filter. It has some drawback -- blue is quite far from IR in the spectrum and most lenses are not optimized for this particular situation so you can get CA between blue and IR, showing as some ghosting. Red (25A) can exhibit this but it is unnoticeable in practice. The effect is never detectable on R72.
