Must-Have Filters for Landscape Photography

Must-Have Filters for Landscape Photography

By Nasim Mansurov

While I was photographing the beautiful scenery of the Glacier National Park at sunrise, I realized that some filters are pretty much required to get good results when photographing landscapes. While many photographers think that some of the built-in tools in Lightroom and Photoshop can simulate filter behavior, making filters redundant in the digital age, some filters in fact can never be simulated in software, while others help in getting even better results in post-processing. If you do not know what filters are and what they are used for, I highly recommend reading my “lens filters explained” article before you continue to read this one.

1) Polarizing Filter

B+W Circular Polarizing Filter

A polarizing filter is a must-have tool for landscape photography. It is typically the first filter landscape photographers buy to instantly improve their pictures and and add vividness and contrast to them. A polarizer can reduce reflections from objects such as water and glass and can be used to darken the sky, bring out the clouds and even reduce atmospheric haze, making the scene look much more vivid. For all normal lenses that have a filter thread in the front, you can get a circular polarizing filter, also known as a “circular polarizer”. A circular polarizer is very easy to use and once you attach it on the front of your lens, all you need to do is rotate it clockwise or counter-clockwise to get a different amount of polarization. Polarizing filters work by blocking certain light waves from entering the lens. Rotating a polarizer allows certain types of light waves to pass through, while blocking other ranges of light waves. Thus, you could turn a sky from light blue to very dark blue or increase/decrease reflections by simply rotating the filter.

The effect of polarization cannot be reproduced or simulated in post-processing, especially when dealing with natural reflections. Take a look at the below image:

How to properly resize images in Photoshop

How to properly resize images in Photoshop

By Nasim Mansurov

If you like sharing your photographs online, whether on Facebook or on your own blog, you should learn how to properly resize your images. While your camera can take very high resolution photographs, it is always a good idea to down-size or “down-sample” those images, not only because most websites won’t accept large images, but also because making those images smaller will actually make them look better, if done correctly. In this quick tutorial, I will show you the proper way to resize images in Photoshop. I have seen people employ all kinds of different techniques when it comes to resizing images in Photoshop. The below method is how I personally do it and it has been working great for me, at least based on your feedback. You can employ this technique to any photograph – whether it is a portrait or a sweeping landscape.

When I wrote about the benefits of a high-resolution sensor, I used the word “down-sampling” when talking about reducing noise and increasing sharpness in high-resolution images. Right after I posted the article, I got plenty of questions from our readers, asking about what the down-sampling process is like and how it can be done. I then realized that many photographers are used to the term “resizing” and have never heard of the term “down-sampling” before. I often use the word “down-sampling”, because “resizing” applies to both increasing and decreasing image resolution (and hence its size), while “down-sampling” only applies to reducing an image.
