What’s Important in a Photograph, and What Isn’t

(John Sherman, May 2016). You know the drill.  You pick up a magazine or browse a website and flip through the photos.  Most you look at for less than a second, but a select few grab your attention and demand a longer look.  What’s different about these select photos?  What makes some photos great and others mediocre?

Why CRI matters?

Article by  Udi Tirosh  (April 30, 2015)

NOT ALL LED PANELS ARE MADE EQUAL. HERE’S HOW TO TELL THE DIFFERENCE.

This article talks about LEDs and CRI. You see not all LEDs were created equal. Most of the time when we talk about LEDs we talk brightness and color temperature, and that makes sense as those are easily measured and have great impact on our photos.

One thing that we often overlook is CRI. And what is CRI you ask? Well CRI stands for Color rendering index and it the number that has the bigger impact on the quality of light.

Let me explain.

You already know that not all whites are created equal. A florescent light is not the same as incandescent light, and those are not the same as an LED light.

Understanding light: 3 key principles of light

Three key principles of light:

  1. The effective size of the light source is the single most important decision in lighting a photograph. It determines what types of shadows are produced and may affect the type of reflection.
  2. Three types of reflections are possible from any surface: diffuse reflection, direct reflection, or glare. They determine why any surface looks the way it does.
  3. Some of these reflections occur only if light strikes the surface from within a limited family of angles. After we decide what type of reflection is important, the family of angles determines where the light should or should not be.

These three principles are statements of physical laws that have not changed since the beginning of the universe. They have nothing to do with style, taste, or fad. Understanding these principles enables us to decide what lights need to be where before we begin to place them.
