Lux meters are best known to measure the intensity of light precisely. Now, the question arises how to measure light intensity using a digital lux light meter. Let us look into it in details : Compute the square of the distance, then multiply it by Pi and next by four. The result is a radius which is similar as the specific space from the source. The next step is to divide the light concentration calculated in lumens by the spherical area. The product is the lux. A correction factor needs to be applied if the light reaches the surface at an acute angle. It is done when you multiply the resultant lux value by the cosine of the off-axis angle. Applications of Lux meter i) Photography and Video Filming - When you measure the light in lux, photographers can easily adjust the shutter speed as well as the depth of field in order to get outstanding picture quality. The lux meter is also a lot in use for filming outdoor scenes as it allows too many adjustments in orde
