Maui Rainbow

All pictures look better with a rainbow in them. The problem is often the rain part.
 
I captured this image during heavy rain and very strong winds. I parked the SUV to provide some protection from both, but only partial protection was ultimately afforded.
 
Definitely use a circular polarizer filter when photographing rainbows. But, be careful with how the filter is adjusted. Improper filter rotation will result in the rainbow being erased instead of being enhanced.
