Pro Low-Light on X20
Been playing around with this tonight as dusk falls with one of my cityscape test scenes. As expected, ISO above 400 does produce quite some noise (compared to APS-C which I'm used to), but the Pro Low-Light with multi-frame high ISO shots to reduce noise does a pretty good job up to ISO2500, and even 3500 if you don't look too hard. And hand-held. It just took a little JPEG NR in LR4.4 and a touch of sharpening/masking to get a perfectly acceptable result IMO for a scene which was actually darker than shown here in the image. I've used this process a lot on my Sony NEX for night shots in the city (they call it multi-frame NR or hand-held twilight mode), but at least I know it's workable even with the smaller sensor X20.
