I am going to shoot a the cattle drive in Fort Worth, TX today at 4PM, which of course is outdoors. This occurs on most weekends at 11 AM and 4PM. I have shot this before but obviously, the timing of the event isn't the best for lighting. Specifically, there is a lot of contrast not only in the longhorn color, but also the shadows and bright sunlight areas (obviously). Today I am going to try to shoot again, this time with my new (yippie ky eyeee) 300 2.8 IS II lens on my 5DII body.
In thinking about how to augment the shadows, I though I would use a better beamer for fill and set flash to ETTL (using a single 580 EXII). I haven't used auto ISO, so I thought I would try that with appropriate manual camera settings.
I would appreciate if anyone can provide me insight for this situation. How does this work? Will the flash control the ISO? What will the camera logically use as priority to set the ISO? Should I make exposure compensation changes or set the flash to manual? I could just set it and forget it I guess, but I really want to understand what is going on inside the camera.
To all who answer, I thank you in advance.
