Making Rainbows Pop

November 26, 2014

 

This is a short article, mostly because I only have one example photo at the moment.  Clearly, rainbows do not like me.

 

When you're learning about a polarizing filter, you'll typically hear how it can cut glare off of water and darken blue skies.  Sometimes, you'll learn how it can also cut glare from a window.  However, one of the things that you may not know about polarizing filters is how they can help bring out a rainbow in your photo.

 

Rainbows are entirely made of polarized light, which should mean that a polarizing filter will completely eliminate a rainbow from your image.  In fact, if you rotate the filter properly, it does.  But who wants to get rid of a rainbow from your photos?  

 

What most people don't know is that a polarizing filter does not just cut out polarized light; instead, at the proper spin, a polarizing filter can actually magnify it.  Typically, you wouldn't do this to a photo, because it adds distracting glare to objects in your frame.  But for a rainbow, it is the best way to brighten colors.  

 

This is very easy to implement: put on your polarizing filter next time you see a rainbow, and rotate the filter until the rainbow pops.  

 

I hope that helped!
