The above shot is an example of why you want to take a polarizer with on a sunny day of foliage photography. The shot on the left and the right are taken with identical settings mere seconds apart. The photo on the right, however, is with a circular polarizer. It’s obvious that, given the right angle, a photographer can really deepen the sky and make those fall colors pop! Once again, I advise doing so quickly. It won’t be long before the only place one can photograph those leaves will be on the ground.
