Faster and faster

Those darned kids, right? we have to add shutter speed. That didn't work for us the last time we tried it. Maybe with the flash on, it's going to be different. What the heck, let's give it a shot.


1/250th at f/5.6, ISO 100

That looks the same to me. The last time we tried to raise shutter speed, it got all dark. How come when we sped things up this time, nothing changed?

The answer is flash. Our flash is going off in thousands of a second. It's firing faster than any child moves. And flash responds to aperture settings, not shutter speed. why? because at 1/250th, the flash is still faster than the shutter. In essence, the shutter is completely open, then the flash goes off in between, and the shutter closes. This is your camera's "synch speed". It's the fastest shutter speed a camera can use and still get a full power pop out of the flash.

Check with your camera's manual to find what your max shutter speed is. It can vary among makes and models. One of the reasons I shoot Nikon is this higher shutter speed.

The image still looks a bit dark, though, doesn't it? This is supposed to be a white bear, and it looks a bit off-grey. what can we do about that?
