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

[Kirk Thibault]

Same thing on my computer at work - I used the absolute path, I have  
the latest firmware ... going to go out on a limb and guess that the  
(or my) Digital Rebel (300D) is not compatible?

The app logs that it writes 6 files - the number I have specified in  
the Param file.  however, it actually writes the same two files three  
times alternating between the two, effectively causing capture 3 to  
overwrite 1, capture 4 to overwrite 2, capture 5 to overwrite 3 and  
capture 6 to overwrite 4, leaving two files (captures 5 and 6) in the  
capture folder.  it always writes the same two files as shown below  
(fun444793328.jpg and fun444793086.jpg).  i suppose these file names  
mean something specific to the image, capture settings or something?   
I wonder why they would alternate repeating, resulting in successive  
overwrites.  The images that are written are actual JPEG images, so a  
valid file is written, presumably each time.

Oh well, I'll keep at it.

Also, it sometimes takes a few attempts for communication to be  
established with the camera (I exit and relaunch the app and it  
eventually works.
