Re: A Test: Flash Exposure Compensation w/ 9 Examples
Good description of High Speed Synch - which makes a strobe act like a Focal Plane flash bulb - remember those?? There is one other reason that I frequently use High Speed Synch for, though. When shooting macro in the wild in a garden, the backgrounds are frequently a jumble of leaves, twigs, dirt, fences, etc. I like to… -

Two additional things: 1. 30D in Av mode will only shoot flash as "fill flash" -- C.fn #03 forces the x-sync speed to 1/250 -- 2. 580EX mounted on 30D --- FEC (physically set on the flash) over-rides any set via the camera. You can use Av mode with E-TTL flash and FEC, but your going to be chasing the exposure, never… -

My point is that you could have taken the same shot in standard sync at ISO200 f/15 1/200 and the background would have been just at dark becase the ratio of the sunlight to the flash power is the same. The service HSS is providing on this shot is letting you open the aperture up to f/10 to reduce diffraction effects. -

Re: A Test: Flash Exposure Compensation w/ 9 Examples
Great thread. I'm happy to see an increasing interest in flash here on Dgrin since it's where I'm focusing my learning efforts right now. I did some similar fill shooting this weekend with an XT and a 430 EX. I was shooting in the middle of the day in a covered patio so had bright, daylight backgrounds with people shaded… -
Re: A Test: Flash Exposure Compensation w/ 9 Examples
I think this last post was a great demonstration of the utility of fill flash and the accuracy of Sunny 16 I like Incident meters too for their superb accuracy. The meter in our cameras always seems to vary a little more from shot to shot. Your comment, Scott, about the limitations imposed by High Speed Synch are very apt.…
