For more... Mountain Visions: The Wilderness Through My Eyes
Another beautiful clear star filled sky in the heart of the Adirondacks forced me to get out my camera and spend a little while trying some light painting.
Star trails are inherently boring without some sort of context and I was too tired to set me camera up and leave it running all night, so I took the short approach with an in camera multiple exposure on my Pentax K-7.
Exposure 1 was 15 seconds at f/2.8 and ISO 1600.
The second exposure was 30 seconds at f/16 and ISO 1600.
The reason I went with such a long second exposure at ISO 1600 and f/16 was that I wanted to not be rushed and I didn't want anything but the graffiti to show up. At such a small f/stop it would be unlikely an errant beam of light would light anything up.
I prefocused the lens to 15 feet, set the camera to 12 second self timer mode, and fired the shutter as I paced 15 steps.
By the time the shutter opened I was ready to paint my graffiti. No fancy computer post processing required, although that of course makes it all the more interesting since the results are completely variable!
The tail off of the light on the "K" is from the headlamp dying. A few minutes later it was gone! It is the first time I have had an LED headlamp completely turn off on me. Strange.
Any way, although it wasn't exactly as I envisioned it, it was a fun little experiment on a pleasant autumn evening when I had nothing better to do any way.
Pentax K-7, FA 43mm f/1.9 Limited, tripod, LED headlamp and in camera multiple exposure.
