Once ready with my rather dark scenery, I challenged myself to play with light effects. It's still hard to do in photoshop because I don't control all the possibilities yet, but now and then I have to practice :-)
Most pictures I have used are personal vacation photo's. (and a few images from riandesign.) Only the moon is from a Dutch photographer;
André van der Hoeven.
(I didn't ask for permission to use his photo but hopefully he agrees with the link back to his Astro-website !)
