All of modern camera almost able to take a photo in 1/4000 or faster with a high ISO performance (Read more about: ISO). The minimum exposure setting when I take a landscape picture is around 1/30 until 1/60, even i sett may camera at lowest ISO (ISO 100) and smallest aperture setting.
So, what is Long Exposure Photography?
Long exposure photography means shoot a photo with long exposure time. The exposure time may around 30 second or longer. Modern camera could not perform this genre naturally without any additional accessories such as Filter that able to reduce the amount of light, Shutter release and tripod.
The reason.
There are a lot of reason why nature (Landscaper, Waterscape or anything produce by nature and Building) photographer remain shoot with long exposure time. Base on my argument, Long exposure photography produce beautiful photo that sometimes can not be imaging before we see the photo result. The idea of Long exposure photography is how to record nature moving object such water, cloud, star or even moving car and walking people into a photo. It is really fantastic to see a moving image such as cloud covering a stationery object (see: Long Exposure Photo Sample). The other object that we can not imaging is Flat water. Shoot with long exposure time make a choppy water in sea becoming flat. It looks like a frozen sea.

The other function of Long Exposure photography is taking picture with very low light source such as on night or twilight. Taking picture in night with high 800 ISO or more produce a noisy picture but help us shoot with high speed exposure time. Keeping the ISO low make a long shutter speed but produce a clear picture with less noisy on image. So, two of those are the choice.
