New HDR script for the A530

I lifted the scipt posted here in 2009, made a few changes so it would work with the newer CHDK and this far older camera. Removed most of what deals with aperture, since it didn't seem to make a difference.  Enjoy.

Question about speeding it up: will dumping only RAW, no JPEG do the trick? Would the RAW files have enough metadata for qtpfsgui?

The A530 only has two aperture settings - full open and 2 stops down via a "Waterhouse stop".  So you probably would not see much difference if you were only changing things by 1 or 2 stops.

You really don't have the option to only shoot RAW - the camera will store the JPG regardless.  However, saving JPGs is a lot faster than saving RAW so disabling RAW is a good idea if you are worried about speed.

CHDK RAW files contain no metadata - they are just a dump of direct from the camera's sensor.  Use DNG format if you want metadata with your images.
