Ok, I need help from off camera flash photographers.
Some info on the photos
Time: 9 PM'ish
Location: Pool
Camera & Lens: Canon 5D with Canon 24-70
Camera setting: F/5.6 - 1/250 - ISO100
Flash: Two 580EX II
Flash setup: Off camera with PW II
Flash location from subject: One at left approx. 35-40 degrees and One at right 35-40 degrees.
What am I doing that is causing the corners have a solid black areas?
I changed to 40D with 70-200 F/2.8 IS with same setup and flash locations but didn't have the same problem.
Is something wrong on the 5D or the glass to cause this?
No edits on the photos. This is straight from the camera.
