Physicists resolved the centuries-old debate on the nature of light by declaring that it is both a wave and a particle, but for most practical purposes, they treat it as a wave. The distance between wave peaks in a light beam is known as the wavelength, and the total range of possible wavelengths is known as the electromagnetic spectrum. The human eye processes visual information by perceiving only a small fraction of the spectrum. sciencing.com My light photograph is titled “Light Show” .

Reflections-and-Refractions-1-31-12

In optics, a caustic or caustic network is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light. A common situation where caustics are visible is when light shines on a drinking glass. The glass casts a shadow, but also produces a curved region of bright light. I’ve been taking photographs of light, shadow and caustic optics for many years.This is a photo that I took in 2012 ,which was before I knew the name caustic.

 

 

DCF 1.0

This is the photograph that began my search for interesting and unusual reflections and refractions of light. I captured this reflection with my first digital camera over ten years ago. The only enhancement of this photo, in the software Photoshop, was to increase the contrast.This was a reflection of light bouncing off the brass doors of our fireplace, that appeared on our living room floor. For me, the important thing about taking this photo is that I “saw” this image and recorded it. I’ve shown this image several times on my blog “Journal of Seeing”.I have previously named this photo “Crown of Thorns” and now I think a better title is “Crown of Light”. 

Afternoon light

As I age I see beauty in simple scenes ,like this scene of afternoon light on my living room wall.

Here are a few more caustic light photographs I have taken recently. I have enhanced these photographs occasionally in the software Photoshop.
