"In golf, a mulligan happens when a player gets a second chance to perform a specific move or action. The day offers an opportunity for giving yourself a second chance or, as some people call it, a “do-over.” We both got a second chance at marriage. Our joke is that we have been married 54 years, ten of them to each other. :-) Second chances can be a gift or they can be a difficult move to make.
Do you have a second chance to photograph?
If not, have some fun taking a double exposure today. Make good use of a "second shot." Check your camera manual to see if you can do a double exposure in camera. If you can't, there are many apps, like Image Blender or BlendMe, that allow you to create double exposure images from single exposure photos. And if you have lots of time on your hands, the Internet has endless tutorials on how to be creative with double exposures.
Have fun. And if necessary, give yourself a second chance!
