Limits of knowledge rev XX

Blue indigo

Night for Day

Open window

Stone wall

Solitude

 Emergence

All these pix show aspects of the great invisible whether it be Night for Day or the infrared driven images of Solitude and Blue Indigo as our eyes cannot see reality in a light spectrum outside of the tiny subset of what we see without the aid of tech. 

The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.

As for the stone wall, this image indirectly shows the passage of time with the oldest at the bottom and the latest at the top. As for Open Window & Emergence, darkness invokes mystery even in the bright of day.

To yours truly, the limits of knowledge resides everywhere, even in the commonplace as depicted in the pictures seen above. :)
