Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. The energy of a photon depends on its wavelength: Longer wavelength photons have less energy and shorter wavelength photons have more. Red photons, for example, have less energy than blue ones.
The Science of Light
Light is a type of radiant energy that we are able to visually perceive with our eyes. In other words, light is power that we can see! Visible light is a small part of a large part of what is called the Electromagnetic Spectrum, which contains all of the energy types that travel through space in a wave-like manor. Every day, light waves reflect off of objects and into our eyes, which allows us to see the objects. Human beings by far have the best visual system structure - even better than a bird, who has to see small objects from high above.
Reflection
Using reflection in photography can lead to some amazing effects and beautiful images. Using water, windows, mirrors or any sort of reflective surface can change an image into a work of art. The wonderful thing about using reflections when taking photos is that they can completely alter the image from something fairly straightforward to something richer or abstract or otherwise more artistic.
Spectrum of light
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nanometer.
Photographer- Dean Chamberlain
Dean Chamberlain is the father of light painting photography and has been capturing photographs since 1967. It was his passion for photography that led him to the Rochester Institute of Technology in 1974 to pursue a fine art degree. During Dean’s time at Rochester in 1977 he discovered light painting photography. Dean was the first person to coin the term “Light Painting” for his open shutter long exposure photographic technique. He has worked with his unique art form ever since in his various works. Dean has created stunning portraits of well known individuals such as David Bowie and Paul McCartney. He has also directed numerous music videos.
