You might get lucky. You might be there, in the forest, on a particular day that’s not too foggy, but foggy enough to create amazing beams of light streaming through the trees. Or, you can do what a number of landscape photographers that I know do and that’s to add light beams after the fact in Photoshop. Or, easier yet, there’s a plug-in for both Photoshop and Lightroom called “Luminar” and their Sun Rays (light beams) feature is pretty darn amazing, very powerful, and super-easy to use. (That’s it in use above right.) If you want to do it all in-camera, there are still some tricks. One is to buy a few cans of aerosol spray smoke (the stuff they use on movie sets. It’s not cheap, at around $12 a can, but it’s easy to use and very portable). Right before you shoot, spray the area where light is coming in, and it creates the beams. It’s the same thing when you’re shooting in slot canyons. You don’t see those light beams whatsoever unless you get another photographer there to toss handfuls of sand up into the air—that’s when you see the beams. Otherwise, it’s just bright light. If you really want to smoke it up so you get mega-beams, you can buy (or rent) a wireless fog machine (yes, they make those) and take it with you on location to create amazing beams of light on demand. So, you can get lucky, or you can kinda make your own luck (ahem).
