Learn why polarizer filters are useful, and how to use them

Back in the days of analog photography, filters were a photographer’s best friend. Today, with digital photography, many of the effects filters had on film can be replicated during post-processing, especially those that concern color reproduction such as the color filters used in black-and-white photography, or graduated filters that would darken the sky while keeping the foreground nice and bright.

But there’s one filter with an effect that cannot be emulated by software, and that’s the polarizer filter. While most of us have probably heard about polarizers before, and many of us may actually own one, we’re sure that some of the tips photographer Steve Perry gives in his latest educational video will open your eyes, just as they opened this writer’s.

One of the most popular uses of a polarizer filter, according to Perry, is to darken blue skies. And while this effect could be achieved during post-processing. Perry explains that actual polarizers help eliminate reflections from all kinds of objects, which in turn will make colors appear much more saturated.

When photographing landscapes, a polarizer not only makes colors “pop” by filtering out reflections from objects such as foliage and stones, it also helps remove some of the haze that can make pictures like that of mountain ranges appear dull. Another great use for a polarizer filter is to look beneath the surface of water, for example when photographing a pond with fish in it.

Finally, a polarizer filter can be used to make a nature scene more colorful even on overcast days, when most of us would probably keep their cameras at home. But here’s another thing you may not have known: when using a polarizer on a wide-angle lens, you may end up with darker and brighter patches in the sky. So if you’re using a wide-angle lens for landscape photography and have a lot of sky in your image, better take the filter off.

These and more clever tips can be found in Steve’s video below. For more, take a look at his YouTube channel where he regularly posts educational videos like this one.

Photography 101: What is a histogram, and how do you use it?
RGB-tonal-histogram

It's easy to set exposure by eye. We've all done it. The problem is that the electronic viewfinder or LCD screen on your camera does not show a 100% accurate representation of what the sensor is recording, and your own eyes may be focused on one part of the image while ignoring another. You could have blown-out highlights or crushed shadows that will only become apparent later when you open the photo in editing software on a computer.

The histogram takes the guesswork out of setting your exposure by showing you a graph of pixels arranged from dark to light. It provides hard data to confirm whether or not you have any areas of the image that are too dark or too bright for the sensor to capture correctly, or what are called "clipped" pixels.

Phone cameras are so good, they’ve finally replaced my camera for work
Close up of the camera on the iPhone 16 Pro and Pixel 9 Pro.

For almost two decades, I’ve carried more than twenty pounds of electronics in my backpack for the slightest chance of needing to capture content for my professional life. My backpack usually contained my MacBook, a full-frame camera with a big lens, a tripod, and an assortment of video and audio gear that I always deemed essential.

As it turns out, over the past two years, many of these items were rendered obsolete, as many companies launched new products that were quickly able to replace technology that I previously considered irreplaceable.
