You are probably wondering what exactly is long exposure photography since you are reading this. So, let me explain what it is. It’s the technique in which not only shutter is left open for a while, but also right choice of aperture, ISO, filters, lens and tripod are the most important factors to implement the better outcome. And, in this post, I would like to share some basic tips of long exposure photography to get you started. These tips will help you avoid a poor outcome.
Requirments for long exposure photography
Basic Requirements are:
1) Sturdy Tripod
2) Neutral Density Filters (ND2, ND4, ND8. Each numbers represent the stops cut down by the filter)
3) Wired or wireless Shutter Release controller.
4) Wide angle Lens (Basic Kit lens 18-55mm is enough if you don’t have wide angle lens)
5) Lens cleaner.

5 basic Long exposure Photography tips you should follow
Tip 1- Clean your lens properly
Before mounting your camera on a tripod, check the condition of your lens. Sometimes, finger impressions and dust are encountered on the surface of the lens. So, I recommend you to use a lens pen to remove them. Otherwise, light trails will not be crisp, and finger impressions show up in the output. Below is an example that shows the presence of light flares if lens is not cleaned properly. So, unless you want to spend hours in front of photoshop to remove these artifacts, you should clean the lens.
Tip 2 – Always Use Manual focus
In case of exposing your camera in low light, your camera will struggle in focusing the subject. So, I always prefer manual focus to ensure proper focus and sharp result. Although few lenses can auto focus in low light, it’s better to choose manual focus. It helps not only to understand the range of focus but also improves the point of view.
Tip 3- Avoid using Auto White balance
White balance is considered as one of the most important settings of digital camera. It’s basically a way to “measure” the temperature of light and to “balance” out the colors of your photography for the desired results. You can see a list of various symbols and a word description for each symbol to choose under the white balance option. I always prefer to choose the appropriate option according to the situation instead of Auto white balance. Otherwise, unusual colors are encountered in the image. For example in the image below, tungsten white balance preset is chosen to add vibrant colors in seascape long exposure photography.
Tip 4- Always use Shutter release controller
A shutter release controller is a device which allows you to control the shutter of your camera without touching the camera itself. The primary use is to prevent camera shake during long exposures. Long exposures will magnify any shake in the camera, especially those created even by steady hands on the shutter release. So it helps to prevent the blur due to camera shake and get sharper results
Tip 5 –Always shoot in RAW
In one of my earlier posts, I have mentioned the advantages of shooting in RAW file format and how it gives you full control over post processing the image. Sometimes, it happens that, ‘spooky’ colors will show up in the photographs because of the stacking of multiple filters. So, shooting in RAW is the best option to remove these unusual colors during post production. In the worst scenario, black and white conversion will help you out to make the better result. Here is the example for choosing the black and white conversion during post production.
