I recently had the opportunity to be front row at a concert and thought what a great opportunity photograph something new in differing light situations. I started by shooting with the flash on, but it looked like I was getting some sort of haze (flash lighting up the smoke and haze in the air). Also noticed two crew photographers shooting with out a flash. So I began experimenting and found the wonderful benefits of the Exposure Compensation button +/- button by the shutter release. So I set the ISO to 200 and the shutter speed priority at 80/sec overexposed from 2 to 4 or so depending on the picture and I was quite surprised and pleased with the results. My question... what exactly is the over exposure button doing? It is not adjusting the shutter speed. Does it over-ride the ISO? Or does it do something else to make it more sensitive to light? You can view some of the pictures here via FLASH gallery exported from LightRoom. There are a few that I adjusted by adding black to darken them to make the subject stand out more and limit the haze lit up by the lights.
