Hey, MKR, I know you use CHDK on a Powershot as well, so maybe you can help me here, but if anyone can give me help with this, it'd be greatly appreciated
When I take photos as RAW files, the noise seems to be much worse in comparison to the JPEG versions. I noticed it a lot playing around with it yesterday

Now, is this always going to be the case, being as this camera isn't truly built to save in RAW, or is this more the cause of the ISO setting when I took these shots (all were indoor/dark outdoors), which were all on auto, around 200.
I mean, In some of my pictures I can really tell the color difference when I take it in the RAW format, but I don't know if it's really worth it if the noise is amplified as well...

Set it to save in DNG, and run the badpixels script (it should be in the test folder). The JPG has this file's map applied, while the RAW is untouched.
Go check out the badpixel page on the CHDK wiki for all the fancy details.
edit: Also, the RAW doesn't have any white balance, color, or exposure corrections applied. The JPG is processed in-camera. I highly recommend RAW Therapee for its sexiness and workflow. |
