EXPOSURE TRIANGLE
Aperture:
Aperture is how opened or closed the lens' iris is. this technique is used to control how much light enter the lens. the narrower the aperture is the less light in the picture. Many wonder why a photographer would want to have a lower aperture when taking pictures. the reason is because doing this gives a larger depth of field. depth of field is a by-product of aperture. The answer the majority of the time is that we want a larger depth of field. Depth of field is a byproduct of aperture. Narrower apertures give a greater depth of field, allowing more of a scene to be in focus. Wider apertures create a narrow depth of field, which can help isolate a subject. |
