In this image which was taken during the day with a clear blue sky I wanted to give the impression of moonlight in a dappled sky. So I pasted in a monochrome sky I liked and adjusted it with the curves tool, added a moon, adjusted the lighting. I also added a number of layers and added the plastic wrap filter to the figurines to make them reflect light better.




This is the original

There are actually cloud brushes available for free from Adobe for those using photoshop or photoshop elements. They are located at :

Once in the opening page type "clouds" in the search block.

Hi Bob, I'm getting 'not found' when I search for clouds, bet I am doing something stupid.

You're not stupid. Something changed on that site & is not responding the same way it did just 24 hours ago. I downloaded a half dozen cloud brushes and actions but now get the same results as you. Sorry! ???

Bums!

Not your fault Bob, thanks for checking for me
