I recently shot an event with my 50D + Sigma 24-70 F2.8 and Canon 580 EX II. I've tried bouncing the flash off the attached white card, but my photos keeps getting overexposed. Any idea why is this happening?
Ps. I've tried to shoot in TTL and M. But the results are either under or overexposed. Super upset with my photos. I ended up shooting without flash.
Pls advice. Thanks.
