While I was waiting for my DP1's return I had a chance to look at some low light images again.  

The first image was shot at ASA 800 (1/4 sec at f4).

The next image was ASA800 -2ev (1/13 at f4)

For each image I let SPP do it's magic in Auto mode. I found that I liked the image better with less saturation so i dialed in a -0.3 and 0.2 respectively.  I looked for neutral gray on the wing of the carved bird upper left of the image.  I can see that there is a difference in color rendition, probably the result of the exposure difference.

Once again, these are not 5 star images and other than the above no adjustments were made.

All in all not too bad
