Re: New (CHDKversion is available for SX40 I see

Thank you for that information, Phil. I actually went to the CHDK forum and learned that you were one of the 'Hero members' there, and also one of the main contributers. So thank you for all that you do.

I guess I will wait for a little longer then for my own CHDK experiements with the SX40 and let you heavy weights blaze the path through the forest first. I'll keep watching here for more of your work and progress.

I was quite surprised that the results you got at ISO 1600 were that good in RAW to be honest. I would have expected more noise than you got. I myself tried a similar experiment using jpg's from both the G12 and the SX40 at ISO 1600 in fairly dim room light. What I saw is that the SX40 was practically noise free due to noise reduction, while the G12 showed less noise reduction and a noisier image. But the G12 also had more detail. In spite of the noise reduction in the SX40, I would have to say the OOC image from it was superior to the G12. It was smooth and quite nice, unless you pixel peeped for fine detail It would have taken quite a bit of PP on the G12 image to equal what was OOC on the SX40. So that was impressive to me.

There are currently two people working on CHDK for the SX40 (ERR99 and myself). We have different camera firmware versions - his is 1.00f and mine is 1.00g.
The version posted on the CHDK forum is an early alpha for 1.00f from ERR99.

I hope to merge our efforts over the next few days so our combined version can progress to the beta stage.

Phil.
