This was my self-imposed lesson in learning to use Photoshop's Blend If sliders when doing hand-blended composites. When I shot this scene in October 2011 I had never really seriously attempted to shoot at night because my camera at the time (Canon 40d) is not exactly known for its low light or high ISO noise capabilities, and when I looked at the files in Lightroom I initially wrote them off as too noisy to expect good results from. Fast forward a year and a half and I thought this would be a good test of my current blending accumen. Turns out that a) I'm better at it than I thought I was and b) I've underestimated what that lovely little camera is capable of for years. Sadly, as I now rock a Nikon D600 I may never find out what it's really capable of. Small sacrifices, right? :)
Technicals - three 30 second exposures taken over about 45 minutes; one for the stars, one for the mountain, one for the foreground. Processed in Lightroom, blended in Photoshop.
