I have a powershot sx40 hs. I have installed the sx40hs-100i-1.1.0-2806-full chdk.
My main problem before installing the kit was that Canon does not allow for bracketing WITHOUT changing the aperture. You can do it manually but that is a big pain. I'm trying to create HDRI maps so changes in aperture are a no-no.
I have a few questions please:
1. Is the any way with the chdk to make the camera take 3 bracketed shots without it automatically adjusting the aperture
2. I tried the RAW format which has more dynamic range but now my photos also have the vignette of the camera lens edges (you can actually get the whole sensor on the raw file and this shows the lens edges). Any way to reduce this to regular size. The problem with seeing the edges is that I can't stitch the photos and it's a pain to crop photo after photo...
Any help of pointing in the right direction would be much appreciated. Many thanks
