musings on shutters and sync speeds

Dec 202007

So this has been bothering me for some time…

So the maximum flash sync speed for a purely mechanical shutter on a dslr is the fastest shutter speed where the flash can fire while the shutter is “fully open” (ie any faster and the 2nd shutter curtain will cut off part of the flash, leaving a black bar over the image)

On the other hand a camera with an electronic/hybrid shutter can theoretically sync as fast as the actual flash duration, since the mechanical shutter is open for a relatively long time, and the “shutter” is actually just the electronic “slice” of the exposure (yes I know that’s not technically entirely accurate, sue me)

I’m back…

Dec 172007

… from a wonderful week in the Virgin Islands.  Unfortunately it rained *every* day, limiting photographic opportunities somewhat, but I still managed to come back with a few shots :-) the weathersealing on the k10d and DA* definitely proved its worth!

Shots are in the sorting/processing stage – will be posted soon!

away for a week

Dec 072007

I’ll be out of town for the next week, so no blog updates. (will be doing lots of shooting though!)  I know I’ve been erratic as of late, mostly due to lack of time while packing to move at the end of the month.  (The upside of this is that my new place will have a ton of studio space, to facilitate making pretty pictures!)

I promise more articles and lots of pics when I get back!
