Here’s a second shot from Mare Island. See the first one here.
Photo tip that I was able to share that night:
Your DSLR may have in-camera noise reduction automatically turned on by default. If that’s the case, for each second of exposure, your camera will take another second to apply noise reduction and you won’t be able to use your camera while it’s processing the image. You can choose to turn this function off and deal with noise reduction in post so gaps won’t show up (if you’re shooting star trails). Plus you won’t waste time standing out in the cold. :)
