You should have your digital camera ready to grab at any given moment. Shots like this one cannot be 'staged'. They just suddenly appear and if you're ready you may be able to capture a moment to enjoy and share for years to come.
I should probably stop right here to say that "Yes, I know many of you have one piece of equipment that does multi-tasking to the Nth degree." My best friend Paula, scoffs at me constantly for my antiquated tools. But, they work for me.
When I go out for my morning walk or run each morning before daylight, I have my cell phone in one pocket, (Yes, I know I COULD use it to take photos.), my mini tape recorder in one pocket and my camera around my neck.
So be ready, you never know when the perfect shot will present itself.
This beautiful white egret sitting on the floating dock at the marina in my neighborhood was just waiting for me on my morning walk. What paradise!
