ISO 1600 boosted 2 stops

I do not have any ISO 3200 or 6400 from my K20D to test with v0.9 of RBC, so I took an ISO 1600 from a theatre shoot and boosted it 2 stops in post.

Original resized shot:

The lighting was quite yellow in the theatre. This is the white-balanced version with 2 stops of exposure boost & 2 steps increase in DR. It's too bright, but I wanted to work with the dark parts in the corner.

100% comparison - Top Left. You can see the decrease in blue noise. WB OK. (No extra NR applied during conversion.)

100% comparison - Bottom Right under the table. The WB goes greenish towards the bottom of the image.

Dan.
