(Also posted at DPReview, but I thought there might be some interest here)
I've been having a play with the SX1 at ISO1600. I think that the conclusion is pretty unsurprising.
It's a small sensor camera, it's not really designed for ISO1600 photos. If you want to shoot ISO1600 on any kind of frequent basis, you really should go and buy an SLR. However, the SX1 might just be adequate for occasional use.
The subject matter was a rehearsal for The Boy Friend (more information at http://www.sabos.co.uk
- I am playing Bobby in it). The hall was lit only by overhead fluorescent lights. It was night and so the windows gave no illumination. The back wall of the hall is (almost) white, thus making it harder for the camera to meter accurately.
And in addition, I screwed up and forgot change the exposure compensation settings on the camera. All of these pictures were taken at -1/3 exposure compensation.
I have tried to pick a sensible size for posting each photo, but I have also included a link to the photo on Flickr, where you can see the full-sized picture.
Here's hoping this is useful to someone, I'd be interested in your feedback.
And of course, if anyone's near Stirling, Scotland and fancies coming along to see the show, please get in touch!

Pretty green, it has to be said.

The people do look considerably more human, it must be said. There is noise that we would consider unacceptable these days, but in truth it's probably better than scanning an ISO1600 film from the 35mm days...

Not sure if this is an improvement. You don't want to look at it at 100% for sure, but it doesn't look offensive on first glance. I don't print pictures, but I wonder whether this would make an acceptable 6x4 or 7x5 print?

Back to the green, and even deeper shadows than before

I've added about 15% shadow boost using Shadows/Highlights. Before that I used the green channel of the levels control to reduce the green cast in the picture
6. Picture #2, added some noise reduction and USM

As before possibly an acceptable print, but no noticeable detail whatsoever!
