blue and black and light

“Visible light is electromagnetic radiation whose wavelength falls within the range to which the human retina responds, i.e., between about 390 nm (violetlight) and 740 nm (red). White light consists of a roughly equal mixture of all visible wavelengths, which can be separated to yield the colors of the spectrum, as was first demonstrated conclusively by Newton. In the 20th century it has become apparent that light consists of energy quanta called photons that behave partly like waves and partly like particles. The velocity of light in a vacuum is 299,792 km per second.”

This is a photograph of light on the corner of two interior walls of my home. I have enhanced the color in Photoshop. This photograph is from my photography portfolio of  light and shadow.

reflection of a glass on a kitchen counter

I took this photo of a glass on our kitchen counter today July 21,2019. It will be placed in a portfolio called Photography- reflections ,refractions and shadows in my website studiodyess.com

“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.
