Photographing lightning can provide some quite amazing results. Such photos generally require a tripod set-up and a slow shutter speed to capture multiple bursts of lightning as they leave their storm clouds and hit the earth. There are many different types of lightning, including the traditional single bolt hitting the ground, to sheet lightning between clouds, the commonly associated forked lightning as well as forms such as ball lightning and chain lightning, to name but a few.
If you’ve ever seen those waterfall photographs where it’s bright daylight but the water appears to be flowing smoothly as if the shutter speed is very slow, you’re probably looking at a photo taken with a neutral density filter over the lens. They basically darken the scene allowing for a longer shutter speed to be used when there is still bright sunlight. Graduated neutral density filters are also popular. GND filters darken part of a scene, e.g. a bright sky, allowing a more even illumination throughout the picture. Below are a few great examples of photos taken with neutral density filters, I hope you enjoy them.
