Thanks understood.
I increase Jpeg size to sensor size value and pics have bigger FOV:)

bether, it is not good idea. Increasing active area, you get thin black borders around the image (these borders are blind areas of camera sensors). Increasing Jpeg size (or crop size) you get interpolation artifacts during developing DNG file. Properly crop size serves to avoid interpolation artifacts

I have a CRW, and a RAW and the results I got from an PowerShot SD600. Even though the chdk is beta for my camera it is pretty much 100% working. I hope this file helps to add support for this camera. If anything else is needed I would be happy to help out.

SD600-Raw-JPG.rar

The results I got were using program 0.2.2. I tried to use the newest beta 0.2.3 b6 , but the New button to add a new camera doesn't seem to work becuase it is disabled, and besides I dont know what to put in the fields for sensor type, active zone, black and white levels and the mosaic type.

xbc you have to use button "Copy" for it. First choose other camera, which sensor geometry equals yours, and press "copy". Then rename new camera name into PowerShot SD600.

The iso value is set to 80 which is the lowest in my camera. Then again I have been playin with all the CHDK values, will try to reset all values to see if that helps. On the focus to infinity is that the zoom factor? I put that in the middle point, if not I am not sure what is that. I am willing to try again, please advise, and thanks for all your help.

I guess I found the infinity focus, it is the mountain icon on my camera. Let me try again and I will post my files
