ring flash question
I just received my ringflash and was testing it out, mind you I've never shot with any kind of flash and here's my query, why does this happen at some shutter and aperture settings.

Re: ring flash question
If you specified what shutter speed you were using, we'd have a better clue. Without it, it is a guess. Perhaps too high a shutter speed, which means that a slit forms the opening of the shutter that moves across the sensor. The brief flash goes off while the slit is open over part of the sensor, but is already extinguishes before the other part of the sensor is exposed. OTOH the transition is normally more hard edged that the blurry edge of the example!

Re: ring flash question
your shutter speed is faster than the sync speed of your camera. (usually 1/200 or 1/250th).

Re: ring flash question
