Hueless, a b&w-only camera app for the iPhone

Powered by our revolutionary live b&w preview, the image you see in the viewfinder is the image you see in the Photo Roll. No post-processing required. […] Adjust exposure for varying light, under/over-expose your photo to dramatic effect and apply color filters to create the image you desire. All on the fly, as you shoot.

I’m kind of in love with this app. Does this portend the purchase of a Leica M Monochrom? No, but damn if it doesn’t make me think about that system a bit more.
