At its very heart, landscape photography is about capturing light on a sensor (or film, if you’re still shooting the old-fashioned way). Photography filters provide a unique way to control and modify that light to create some stunning images like the one you see below.
But how do I go about building my photography filter kit?
If you are just starting to think about getting filters, the process can be confusing due to the many options that are available. In this article, I attempt to explain what factors to consider when you start to build your filter kit.
The first thing you need to learn about filters is what they do and how they affect your images. This helps determine which filters to purchase and how to use them effectively to capture photos like this one from Iceland.
A circular polarizer is the first filter I would purchase. This filter reduces or removes the glare from a reflective surface caused by scattered light. While there are plenty of circular polarizer effects software presets, there is no way for software to accurately reproduce the effects of a circular polarizer. You can see the effect of a circular polarizer in the images below.
ND filter is my second choice. This filter cuts down the light entering the camera and allows you to slow down your shutter speed. We use this filter to produce the silky smooth effect in the water as seen in the image below.
An ND filter allows you more options to explore creativity as seen in this video.
If your Photoshop skills are exceptional, you may be able to manually produce a few ND filter effects. However, this takes a lot of time and effort and is, at best, an approximation of what a real filter can do. An ND filter comes in different strengths. For someone who is just starting out, I suggest one between 4 and 6 stops. If you can afford it, I suggest picking up two ND filters – one between 4 to 6 stops and a 10-stop filter.
Graduated Neutral Density (GND) filters can be used to reduce the dynamic range of the scene you are photographing. They also allow you to capture proper details in both highlights and shadows. Today, HDR software can very effectively replicate the effects produced by this filter. If you are on a budget, this is one filter that you can skip. If you were going purchase this filter, I suggest purchasing a 3-stop soft GND filter. This is one of our most used filters. Here are couple of images taken using the GND filters…
Type of Filters
GND and ND filters can be square or rectangular filters or circular filters. We highly recommend that you start building your filter kit using square filters because of couple of reasons. First, if your kit is selected properly you can stack multiple filters without producing vignetting. Second, rectangular GND fitlers can slide up and down as needed so you do not have to place your horizon in the center. You must also purchase a filter holder and a carrying case but this allows you to extend your filter kit as needed. A filter holder can also accommodate different size lenses with just a step-up ring. We typically purchase a filter holder to fit the lens with the largest front element and then get step-up rings for smaller lenses.
How to Purchase
If you decide to go with square filters, you must purchase a circular polarizer that works with your filter holder without producing vignetting on your widest lens. It is best to purchase a filter kit from a single vendor as it is easier to ensure that different parts fit together properly. If you decide to combine filters from different vendors, do your research to ensure that all the elements properly fit together.
