In my opinion that is throwing away an ernormous amount of information and control. I only shoot in Raw, hence RGB, not greyscale files. Generally speaking, a UV makes sense for photos of the sky and clouds anyway. All of my lenses have UV/IR filters fitted full time. I'm working on coding some of them (only my 50 is 6 bit). Raw and processing in Adobe Camera Raw/Photoshop CS3 offers huge advantages, including when the intent is to convert to a greyscale file (or toned BW). That combination offers by far the largest number of possible tones, which may be placed as you wish within your dynamic range. What's that for an M8, maybe 6 stops?? Someone with more experience than I might like to chime in there. Those 3 gazillion linear tones get morphed into our non-linear way of seeing stuff. In the end the files are much more robust and hence editable. If you have a chance, take a look at what Lightroom or ACR and/or PSCS3 will do for you in new BW options. I follow your point on not wanting to filter IR and I'd be very interested to see anyone's work displaying examples there. I confess that I am not personally enthusiastic about IR photography, but I don't think that you are referring to that specifically.

I've only been using it indoors with people (clothing) photography (when I remember to put it on...) My understanding is that the M8 provides better gradations of gray because it doesn't have an IR filter on the sensor. Thus I'm thinking that for BW not using the filter makes for more information. This just from my readings; it may be just theory... Any thoughts?

This is from walking the dog here recently. We've been having Graham clouds here several times a week for six months or so. Bless you La Nina. UV/IR only. PSCS3 conversion simulating deep red and blues tweaked further. Even put some grain back for nostalgia. <http://www.pbase.com/image/95983277> Comments always welcome.
