Camera Support #12608
Noise profile: Canon PowerShot SX160 IS
git master branch
Noise profile for Canon PowerShot SX160 IS using chdk.
- Category set to Darkroom
- Assignee set to rawfiner -
Just to be sure, is that all the possible ISO values for this camera? I mean, for instance, no value in between 800 and 1600?
The profile fits nicely for lower ISO values, but I am not confident about the values above ISO 1600 (included). It would be nice if you could remake the noise profile with a different set of images to be able to confirm the values obtained. :-)
The official camera firmware offers ISOs 100, 200, 400, 800 and 1600. The chdk-firmware-extension allowed to choose any custom ISO value from about 10 to 10000.
However, I don't possess this camera any more, so this is the only data I can provide.
Ok, so I am afraid the only thing we can do is waiting to see if with a later version of the noise profiling tool we get better results...
Please keep your raw files, to be able to redo the profiling if it gets updated.
OK. Will anyone update this ticket, once the tool received a significant update?
And can anyone point out, what kind of improvement is desired?
Yes, I will let you know.
Basically, (among other things) the curve fitting code could maybe be improved, which would maybe result in an improvement for your images.
