5 Tips For Long Exposure landscape photography

By Samuel Burns


1. Three legs are better than two. A tripod is absolutely essential, but rather than running out and purchasing any old tripod I strongly suggest saving up for a well built model from a reputable tripod manufacturer, Gitzo and Manfrotto are two that spring to mind. A tripod that is poorly built or overly light weight for your camera will be next to useless as it will shake with any light breeze or even under the vibration of your cameras shutter.

2. Shoot with a low ISO. Contrary to what may first make sense when shooting in low light with a tripod don't jack up the ISO, simply use a longer shutter speed. By increasing the ISO you will increase noise, this particularly becomes an issue in long exposure photos so set your ISO nice and low.

3. ND is for me. The neutral density filter can be used to great effect in landscape photography. Sometimes you are shooting on your lowest ISO and smallest aperture yet you still desire a slower shutter speed. This is where the humble ND filter steps in. Available in a variety of strengths I recommend picking up a couple and having a play with slowing your shutter speeds even further.

4. Film is great for long exposure photography as it doesn't build the noise that digital sensors do, if shooting film however you must be aware of a trait known as reciprocity failure. Essentially it is a phenomenon whereby films sensitivity to light changes with exposure time. The easiest option for dealing with this is to find a "reciprocity chart" for the specific film you are using and refer to this when calculating exposure times.

5. Torch it baby! No No, before you go setting things on fire just hold on a sec. The torch I'm referring to may be less fun but is an essential item to carry when heading out and about for some long exposure photography. Yep, it's one of these battery operated light making gizmo's. When shooting long exposure photos it is often approaching darkness or times of low light so having a torch handy makes life much easier than feeling around for dials and buttons.
