I tried shooting star trails during the Perseid Meteor Shower last night – my first star trails with a digital camera.
As I was finishing up processing, I was playing with color casts. I couldn’t decide which one I liked most, so I put them all in a single image and post it here. I’d love to hear what you think of it.

Third one for sure, you could try out my free presets too http://www.davidkinghamphotography.com/night-photography-lightroom-presets
