First off great forum-

I own a Canon Powershot SX10 IS Firmware 101A
I have installed and have running the CHDK Firmware... sweeetttt loving it!
My question is this:
Can I lock all settings for the ISO, White Balance, Aperture and Focus with only allowing to adjust Shutter speed as needed?
And how?
I am trying to get a set of various exposures to create HDR imagery.
Also, my camera right now takes only 3 exposures - I can take 5 or more with CHDK? Is that right?
Thank you!!
