High-Speed Camera Grabs First 3D Shots of Untouched Snowflakes

First, 1/200s is a very common shutter speed, yes, but most cameras can shoot at at least 1/2000s and most high-end cameras can shoot at 1/8000s...assuming, of course, you have enough light.

Most high-speed stills photography is actually done with a slow shutter speed; perhaps even a shutter left open for a couple seconds. Motion is stopped by the short duration of the flash burst. And with, for example, a Canon 580 EX II flash, you can get a 1/35,000s flash duration. Granted, this will be at minimum power...but they're operating at macro distances, where you can put the flash head almost on top of your subject and still overpower the subject with light.

Don't get me worng; this team is doing some nifty stuff. But it's also something that most professional photographers could easily replicate with the equipment they already have -- and that anybody who specializes in macro photography will probably already plan on playing around with next winter after reading this article.

What the team is doing that's interesting isn't the photography. It's the 3D reconstruction and subsequent analysis and modeling. Making it seem that it's about the photography, which is the easy and inconsequential part, really detracts from the good stuff.

Cheers,
