I thought I'd look through the countless thousands of RAW files I have and start processing them.
First up is one I shot at Chaco Canyon, New Mexico a couple years ago. It was a nice moonless night and about as dark of skies as you can get in North America.
This is a single image processed in Photoshop and using the Nik Effects software. No color was added to the photo, just tweaking the adjustments to bring out what the RAW file had in it.
Nikon D600
Samyang 14mm F2.8 lens
F/4
25 second exposure
6400 ISO
For some reason, the Flickr photo look much more grainy and not a good representation of how it looks in Photoshop.
