If you understand the limitations (you got to have the flash real close) then it works perfectly.


Which is why I use regular flash instead of high speed sync: you have to be close to the subject and I am usually farther away. High speed sync significantly reduces the power output of the flash; you can run into insufficient light shooting group portraits where you have to step back some to get everybody in.

I've used five stops of neutral density filters to get to 1/200th on the shutter at 100 ISO.


ISO 50 also is a help..even wish to have 25...

this is true, if you have HSS off. if you have it on, i think the flash duration gets locked to whatever your shutter speed is. try it -- take a picture of moving tap water or something at 1/250th with HSS on, and 1/160th with HSS off. you will see motion with HSS on if the shutter speed is low.

Not sure I follow all that but you mention a flash duration of 1/250th. My understanding is flash off a speedlight is much faster than that. To my knowledge, a flash at 100% full power will have a duration of around 1/1000th of a second and as the power is cut [say 1/2 power, 1/4 power, etc.] the duration becomes shorter, into the range of 1/5000th or faster.

I usually try to avoid that. I've heard that those lowest ISOs tend to clip highlights.

I use HSS only when I need to stop motion that's decently fast with the aperture almost fully open. This is normally when it's darker and I need external flash to light as well as stop or slow motion down like people running, lights going by fast, or something that I want frozen in time.
