How to do fog photography

I forgot to share this video last week, as it went live while I was on a plane (new adventures coming soon!). Anyway, one all about fog photography, my favorite conditions to shoot in. Tips, how to compose, how to edit, camera gear and settgins, drones, and some words about safety.

Wildfires: beast and beauty

Wildfires are hell. Not only because of the destruction they bring to the wildlife and humans living around it, but also because of the effect of the smoke they produce that can reach lands thousands of miles away.

I've experienced this a few times while living in Portland. Once, we left a window cracked during a smoky day, and came back a few hours later to an apartment covered in ash.

And yet, the apocalyptic and eerie scenes the smoke creates can make for incredible photographs. We've all seen images from New York City this week, affected by the smoke from wildfires happening in Canada. So horrible, yet so incredibly beautiful.

Similarly to fog, the smoke hides whatever is far away from you, while revealing in great detail the objects closer to you. It does have a distinct feel, though: it pollutes the whole landscape. Plus, these conditions happen at times when fog does not usually happen: there's nothing more dramatic than the Sun coming through a thick layer of smoke.

These two images are examples of some work I did in very smoky conditions. The first one was made in the Columbia River Gorge, Oregon, back in 2017, when wildfires in Alberta covered the whole PNW with smoke. The second image was made last year in Riaño, Spain, during a day with very strong calima (sand that is blown away from the Sahara desert, not from wildfires but the exact same effect).

Be cautious if you decide to adventure in these conditions, though: the danger to one's health can't be understated. Wear a good mask, and don't spend too much time outdoors anyway.

How I predict fog

I love fog. Fog is very important for my photography, as it creates the atmosphere and the mystery I look for with my images.

As you can imagine, being able to predict (or at least have some degree of confidence) where and when fog happens can make a big difference. That’s why I always keep an eye on some key numbers that are a good indicator of possible mist.

I use an app called Clear Outside. It’s not a good one, it’s old and hasn’t been updated in years, but I love how simple it is. I can see everything I need in one quick glimpse, with no distractions.

What I look for is:

  • Wind: as little wind as possible, ideally no wind at all.
  • Rain can create its own fog, but most of the time it will leave you with images that look like they were taken on a cloudy day. Only that you got wet to make them.
  • Humidity: has it rained lately? is the ground wet? are there lakes nearby? Here where I live, fog won’t happen if humidity is below 90%.
  • Temperature: a cold night followed by a warm day can fill the air with all that humidity present on the ground.
  • Dew point: the closer to the actual temperature, the better. It is when these two values are the same that fog appears to be the thicker, at least in my experience.
  • Topology: valleys are more prone to fog, as they “trap” that humidity.

This is not an exact science, quite the opposite: predicting fog is really hard. But with the right numbers, and some knowledge about the location, you can have a rough idea of what to expect. And maybe have your camera bag ready to go, just in case.
