This is a combination of two hand-held shots. The carousel in the foreground was photographed at 3 seconds and f/22 at ISO 64. The three second exposure produced the filigree effect. The Eiffel Tower in the background was shot at a relatively stable and sober 1/5 of a second and f/8 at ISO 200. The two exposures were combined in Photoshop.
By the way, I’ve been asked if I am in Paris because of the Paris photos that are appearing on my blog such as Beneath the Pont de la Concorde. No, I am home in California, and just working through and processing some images from the last few years. With the press of the things going on right now in my life, it does sometimes take me a while to get around to post-processing my work!
