Another look at it. I have done quite a bit of this over the years, but I'm having trouble finding some of them. Here is the cabin:
In that shot I had my daughter and EricL inside holding lanterns leaving them on for a few seconds of the image to light the interior without blowing it out. The whole image was 15 minutes of exposure and during the time the shutter was open I used a flashlight to paint the outside of the outside of the cabin. The stars moving through the sky and hint of the northern lights took care of the rest!
Here are two more light paining images.
For these two images I put the skulls on a metal stand I fabbed up. With about a 30 second exposure I lit up the side of the skull with a small LED flashlight. Then before the shutter closed I shined it through the back of the skull pointing out the eye socket to light that up. Took a little experimenting to get the shots I was looking for, but it worked out exactly like I had pre-visualized in the end! Its pretty fun to experiment with that stuff. I met a guy back in South Dakota that did several minute exposures of people that would hold perfectly still and he came up with some mind blowing portraits, but he had an actual photo light painting machine. I always thought someday I might get that serious about it, but never have.
I will take you up on that! I think that could be really cool!
