I had some fun with the sunset last night, 20 minutes of 10 second exposures to create a painted look in the sky.

Focal Length: 24

F-Number: 25

Exposure Time: 10 seconds ( Multiple pictures)

ISO: 100

Time: 8:05PM

After I brought all the pictures into Photoshop I simply left my first picture as a base, then set all photos above to "Lighter Color".  That takes all the darks away and only leaves the light colors which in turn creates the movement in the sky.
