What Does ND Stand for in Photography?

You might want to do this in order be able to use a wider aperture on a sunny day, to maintain a shallow depth of field, or you might...

One example would be photographing daytime seascapes where you wish to use a long exposure time to allow blurring of the water to create a sense of dynamic movement.   F-Stop Reduction Optical Density Filter Factor...

What Is a Normal Lens and How Is It Used When Taking Photos?

A scene viewed through a normal lens appears to have the same perspective as the way your eye sees it. Most 35mm cameras normal lenses have a focal length of approximately 50 mm. Normal lenses are extremely popular with street photographers because the perspective captured in an image shot with a normal lens will be extremely true to life, having the...
