How can we get good night photos ?
Night photography is quite difficult because there is not enough light, and the camere must pe posted on o tripod
Better night photos can be taken after it rained, because reflexions appear
during night is easy to get lighnings, because you must use a long exposure time
What do we need?
A camera with B exposure time (Bulb)
In order to get motion light permits that
a very brightnes lens system, zoom is not preffered because there is not enough light
a very steady tripod in order to get the objects unmoved
Remote control for the camera ( this is optional if you have a very steady tripod) This helps not movind the camera during taking the photo
