I looked at Kodak's tech info on T400CN ><Snip> I'm gonna say again that there was an article in one of the better photo mags a few years back on B+W filters and one of them, I think the (light Red) has the interesting quality of not extremely increasing contrast like all Red filters seem to do and make for easy to print negs. B+W seem to specialized in making all kinds of Red filters in a huge variety of spectral cut off points. I see in the B&H either the dark or light red they are not carrying all ten in stock of course. I've got plenty of light reds I'm going to check out the dark reds for those black skies...sounds ok to me!!!:) Mark Rabiner
