This scene was a staple shot of regional landscape photographers for many years. To get it, pick out a spring evening with showers and sunbreaks, and hang out in your car at Chanticleer Point until a shower passes by and the sun begins to come out. Sounds easy, doesn't it?
I made quite a few trips for this shot before I got the opportunity to shoot it. But I blew that first opportunity, and another opportunity later for a very spectacular rainbow.
I learned a couple of pretty obvious technical lessons from those trips. First, check your camera settings at the outset. I lost one set of shots because the autofocus accidentally was turned off and I didn't notice.
Another lessons I learned on a really spectacular opportunity - check your battery before you leave home. That was the first and only time I have found myself in the field with a completely dead battery. It wouldn't even turn the camera on.
The third lesson I learned from this experience is that every rainbow that I saw at Crown Point was completely different in terms of intensity, lighting, and background clouds. I think you could photograph a half dozen of them, and they would all be different.
