I need to do more low light testing to see what the HX9v is capable of. Of course, I would not expect it to perform well considering the size of the sensor.
I have yet to check out handheld twilight and other scene modes for night and lowlight shooting.
This image is shot in low light enviroment using intelligent auto mode. The HX9V tries too hard to minimize the grain and color noise, but as a result, it "mushes" details from out of focus subjects. In this particular sample, the train and the walls were "mushed"—not only the details were lost, but the structures get crushed, resulting in pasty, watercolor painting effect.
I take this as a challenge/character of the HX9v and try to make something out of otherwise a poor digital image. Adding some blurriness and vignette often hides these issues.
