As I paint more nocturnes I'm learning more about what works. Here are some key learnings I want to share with you.
1. Have a good light - I use a book light with a cobb LED. This type of LED is so bright, it's amazing. The clip end houses the 2 AAA batteries which run for hours. Get a light with a balanced light color...not too blue or yellow. New, high output bulbs produce a nice white light.
2. Pre-tone your canvas a dark color. I'm still experimenting with this but find that if I tone my canvas black or some dark mix of an earth tone and ultramarine blue and let that dry it is much easier to start the painting. If you start with a white surface you have to lay down a lot of darks...which will muddy up your lights when you go to put them in. Much of this struggle is eliminated if you begin with a dark, dry surface.
3. Slow down and enjoy the painting. Take time to let your eyes acclimate to the darkness. There is so much subtle variation and there is no hurry since the light sources are fixed (signs, street lights) and you don't have any moving shadows. Basically, depending on the scene, you might have all night so take your time to really see the color and value relationships and work to get those right on your canvas the first time. Having said this, I have been happily painting a scene when all of a sudden the main lit sign in my painting shut off for the night. Oh well, that happens....just pack it up and try again another night.
I painted "1AM At The Crossing" out in the country. It took me about a couple hours and I wrapped it up at about 1:30AM. I parked off the side of the dirt road and painted from inside of the bed of my pickup. Only one car passed by the entire time...otherwise there was no other light source and no people anywhere around. It was so peaceful and relaxed. I learned a lot by taking my time on this one.

I made the painting below over three sessions, starting at dusk each night so I could catch the transition where the lights on the dam were on but there was still enough light in the sky to make out the mountains and trees.



Happy painting!
