Long exposure photography is not a new type of photography, but it is one that is gaining in popularity. Many photographers are buying Neutral Density filters (ND Filters – more on them below) to capture their own long exposures. It is quite an addictive form of photography. Over the last couple of years I have added many different ND filters to my kit. I use Formatt Hitech filters, though there are other brands that have them as well. Here are some reasons why I love this type of photography.
Note: Neutral Density filters or ND Filters are designed to restrict the amount of light that enters the lens and camera. They can either screw onto the end of the lens or you can buy brackets that will fit square ones. They came in different densities, and how dark they are is referred to by how many stops of light they block. The most common ND filter is the 10 stop which many brands make. The neutral refers to them having no colour, supposedly. They are meant to have no colour and cause no colour cast in your images, though the more stops the filter has, often the more likely you are to get some colour cast. Cheap ND filters always have a colour cast, usually magenta. If you want to get serious about doing long exposure photography, then purchasing good quality filters from the start is something you will never regret.
One of the more popular ways of using long exposures is to smooth out water to make it look still or frozen. This can be done with the ocean, rivers, and lakes. It can make the water in a scene less distracting because the water doesn’t have any movement in it. The image is then more about the sky, the rocks or whatever else is there.
Another alternative is to do long exposures of around a second, so you can see the movement of the water. As the tides come in and out on the beach, you can see where it has been, it almost looks like a slow motion capture. It’s a wonderful effect and we are seeing it a lot more. Though water moving on the beach isn’t the only way to use it, water falling over rocks can be just as engaging.
Waterfalls are another type of long exposure that people love. Though many waterfalls are down in canyons, you still need a ND filter to get that smooth marshmallow effect with the water as it flows down. Though, you don’t often need a multi-stop one like you would for the previous water examples.
Architecture is a very popular subject for long exposures because you can blur the clouds. It gives the image a different look, and it almost seems like your subject is lost in time. With blurring the clouds, it also makes the building(s) you are photographing your main focus point, and gets rid of any distractions.
If you love photographing areas in towns and cities, but one of the challenges of that type of photography is that people are always around, long exposures using filters will help you clear those distractions. Exposures of several minutes can almost clear a scene of people, though it depends on the density of them. A scene where there are only a few people walking around can come out with the appearance of being empty with a long exposure. However, where there are many people you will find that they just blur, though this can be a great effect as well.
Once people are introduced into a scene that you are photographing, it brings with it noise, as in how people see the images. They can be noisy, and whether people looking at the images realize it or not, they hear what they would hear if they were actually there. Vehicles can have a similar effect.
If you do a long exposure of the same thing, that noise is gone. Often when you see a long exposure image it has a quietness to it. Fill a room with images done this way and put people in it, they will feel as though they have to be quiet.
In every city around the world there are iconic places and scenes that everyone is trying to photograph differently than others. If you have some ND filters and your tripod, you can create an image that not many others get. Especially when travelling, not many people have filters with them. You would have an opportunity to get something quite different to the thousands of other photos that are taken in those places. Of course it is a given that they are places where you can set up a tripod.
When you have images of clouds being blurred as they go over the top of a building or a landscape, it seems like you have captured time. Many people feel like they are looking at time passing. The long exposure is taken over a period of time, so it makes sense that you would get that feeling when you look at those images.
One of the great aspects of long exposure photography is that you can set up your camera, your tripod, and slot in your neutral density filter, but you won’t know what you will get until the image is taken. It will give you an image that is nothing like what you can see with your eyes. When you get the images onto your computer it is always a surprise to see exactly what you have captured.
Night photography gives you an opportunity to take photos and not have to worry about filters. You can expose for however long you need. If it;s a windy evening and there are clouds in the sky, you will get movement in your images. If you are taking photos across a water way, then the water will be smooth, and you will get reflections of the lights if there are some on the other side. For all the reasons stated for long exposures, night photos have the same effect.
These are the reasons why I think long exposure photography is wonderful. If you are curious and want to try doing these then I am sure you will become addicted like many others. If you already do them, you might have your own reasons and perhaps you would like to share with us what they are in the comments below as well as your long exposure images.
