Nikonians 2010 Image of the Year
Nikonians March 2010 Contest Winner
Tripod Mounted D700
Nikon 50mm 1.8 Lens
2 Second Exposure @ f/8
SB-600 in Umbrella, triggered with D700
Flash in TTL Mode with -0.7 EV
For this shot I set my D700 up inside the house, facing outward. I placed my SB-600 unit up inside the metal frame of an umbrella and the sensor on the front of the speedlight secured it within that framework so that I didn't have to tie it down each time. This was a big deal because I didn't have to dig through the basement to find string or something similar...
I asked my wife to stand-in on a mark while I locked down the focus. After focusing on her face, I changed the camera to manual focus mode. From that point forward, as long as I stood on my mark, I was good-to-go with regard to focus.
The flash was set to TTL with a negative EV dialed in as to not overpower the shot with blown areas, and I began with the camera set to about 1/125th of a second. This produced some nice shots but the rain was frozen as round droplets and it didn't give the desired effect. So, I began to slow the shutter down to draw out the droplets into streaks as you see above.
Now, the flash is what freezes the action and not the shutter, in this instance. You might think that slowing the shutter speed down to 2 seconds wouldn't have an impact on the look of the photo because the flash should still do its thing for the fraction of a second it's firing. My guess is that the Nikon CLS was maintaining communication between the camera and the flash and when I slowed the shutter down on-camera, the camera then told the flash to extend accordingly, providing a longer period of time during which the drops could be seen.
I grabbed some glasses and a book from the shelf to add some weirdness, and to ensure that my wife called me a 'big dork,' and was good to go...
