Inverse Square Law of Light Explanation from Karl Taylor

June 30, 2014 By Eric Reagan

[youtube https://www.youtube.com/watch?v=373eg4BW-NM&w=700]

Karl Taylor is back with another solid video. This time he’s breaking down the sometimes difficult-to-comprehend concept of the inverse square law into more understandable terms.

The inverse square law in photographic lighting says, the intensity of light radiating from a source is inversely proportional to the square of the distance from the source. As a result, an object 2 meters away from a light source, receives only one-quarter the light as an object that is 1 meter away from the source.

Check out Karl’s video embedded above for a practical demonstration of this principle. And notice how Karl demonstrates it by shortening the ratio of distance between the two subjects and the light source.

Fuji Optical Viewfinder with Zoom Patent Drawing

Who says you can’t put an awesome optical viewfinder in a compact camera?

Certainly not Fuji, who has been knocking it out of the park with cameras like the X-T1 and X100s lately.

In a recent US patent application, Fuji seeks to patent an optical viewfinder that has optical elements inside and zooms to match the focal length of the camera’s zoom lens – or as Fuji calls it in the patent application a “Real-image zoom viewfinder.”  [Read more…]
