Long exposure (also known as time exposure) is where the photographer uses a long shutter speed to sharply capture any still elements of the image, whilst blurring any moving elements, for example capturing a street with moving cars. Long exposure also lets the paths of any moving light sources become clearly visible.
This sort of photography is usually used at night, in order to produce a near daytime effect in the photo. Leaving the camera's shutter open for a longer time allows more light to be absored, therefore creating a brighter outcome. If the camera is still, on a tripod for example, whilst the shutter is open, the photo should be very clear and vibrant.
The time exposure technique is used when 'light painting'. To light paint, the scene must be very dark whilst a light source, for example a small penlight, moves about in patterns, and the light source can even be turned off and on whilst making the pattern.
My reason for researching long exposure photography is because I plan to use this effect in some part of my product, for example the digipak, as Lana Del Rey's genre of music is indie/pop, but the remix adds in the dance/electronic genre, and I feel that both the indie and electronic genre have an abstract side to them, and long exposure photography can be seen as being quite abstract.
