[Hdri] HDRI capture program for Canon EOS cameras under Mac OS X

[Gregory J. Ward]

Hi Kirk (and other EOS 300D users),

I've uploaded a new version of CanonHDRcap for Mac OS X to my  
website, same URL:

I've put in a workaround that should hopefully fix the problem with  
the Canon EOS 300D (Digital Rebel).  The image file name is made from  
the sequenceID returned by the camera, which seems to be garbage in  
the case of the 300D.  I simply reset to 1 any values over 9999, and  
start doing my own count.

To make this work, I've added a new line to the CaptureParams.txt to  
control whether or not the program will overwrite existing image  
files.  This must be set to 0 for proper operation with the 300D, and  
you'll probably want to set it to 0 for most other situations as well.
