What makes long exposure images special is that each image is unique.

Here you have some tips to learn how take long exposure image depending of the kind of photo you are searching.

Blury Sea Water:

If you are shooting in “the golden hour” use slow shutter speed (3-20 seconds) for a longer exposure and a small apperture, wide-angle lens and a tripod.  The longer the exposure the more misty the water appears. Use your camera’s self-timer or a cable release to take the photo with absolutely no blurring. Don’t use flash.

Blury River Water:

Use slow shutter speed (1/15), set a small apperture like f10 or smaller for a greater depth of field and a tripod.  The longer the exposure the more misty the water appears. Don’t use flash.

Light Trails:

Use slow shutter speed and a small apperture and a tripod. The longer the exposure, the more lines will appear.

Star Trails:

Use a tripod and focus the lens to infinity. Set your aperture to f/4 for optimal results, set the camera to B “Bulb” shooting mode and keep your ISO at 100 to keep the digital noise at a minimum. These exposures can be 20 minutes to several hours long.
