Nighttime time lapse

Most photographers are loathe to share their failures with the world.  Rather, they post their best work on their web site or blog, leading to the belief that they always are successful.  As the Artist-in-Residence, I wanted to explore new techniques and share my creative process through this blog.  Today, I am sharing (another) not so successful effort.  It’s that darn night sky.  First, it was my less-than-successful star trails effort.  Now, it is my first time lapse featuring the night sky.  The objective was, through time lapse, to show the Earth’s rotation through the movement of the stars at night.

As I was not going to have a lot of sunlight during this exposure, I just used the Powerbase battery as my power source.  I set my camera to 400 ISO, aperture priority at -0.3 compensation, and f/4.0.  I was not sure if the aperture priority would adequately expose the night sky, but thought I would try.  That turned out to be not a good idea.  The starry night was severely underexposed.  Even adjusting all of the nighttime shots in Lightroom by increasing the exposure four stops was not enough to overcome.  Next time, I will set the ISO higher and use a manual exposure setting for the night sky to make it show more clearly.

The other problem I ran into was the plastic bag I used to protect my camera in the event it rained in the evening.  At some point in time, it became loose and started flopping about, forcing me to delete many images from the series at around the time of sunrise.  Where is a good roll of duct tape when you need it?  Again, lessons learned.

As dark as it is, you can still see the stars rotating and some aircraft moving through the sky.  You will need to maximize the slide show to see everything.  The pixelation is the result of a smaller format jpeg needed to create a smaller slide show that can be uploaded to the web.  Enjoy!
