Photographs by Andrew Davidhazyall images copyrighted but commercial reproduction rights or individual prints may be obtained from the authorThere are several mini-exhibits available. You are invited to poke around as I have not compiled an index of what is available. Let serendipty be your guide!
High Speed, Technical and Flow Visualization
Photographs:
Interference Colors in a Thin Soap Film
More Panoramic, Peripheral, Linear and
Circular Panoramic Photographs:
Additional high speed and stroboscopic
photographs:
A few more high speed photographs:
Vortices in water, objects falling and in constant motion:
More scientific and technical
photographs:
Pretty Pictures in Nature:
More technical and scientific photographs: Microscopy, high speed recording of air bubbles, polarization, stroboscopic coin toss or flip, etc. Collection of Conical Panoramic Photographs: made with my probably unique rotating film strip camera in this case used for panoramic work in several cities including Budapest, Paris, Cambridge and Washingtom. Bouncing Balls Here you will find a small selection of stroboscopic photographs made of a bouncing ping-pong ball showing the loss of height on rebounding from a hard surface and also the instantaneous position of the ball over time. The strobe frequency was set to 25 flashes per second. For those interested the distance moved can be determined based on no other scale then the diameter of a ping pong ball. The Rising Air Bubbles Page: is a collection of photographs of air bubbles rising through various liquids such as hand soap, shampoo, and water. High Speed and Technical Photographs: This is actually a "traveling" collection of photographs available for exhibition. They are ink-jet prints in frames (16x20 Nielsen behind plexiglass) and there are about 25 of them. While no exhibition fee is required shipping and insurance expenses must be covered by exhibitor. Contact me at andpph@rit.edu to arrange for loan. Shotgun Firing and Muzzle Blast: This is a series of photographs of the discharge of a 20 gauge shotgun showing the muzzle blast and the separation of the pellets from the wad, or sabot, as its petals open up allowing the pellets to fly free. Each photograph is a different discharge of the shotgun with the delay adjusted slightly to make the picture earlier or later in the process. Spectral Rainbow: This is a series of photographs of a spectrum, or rainbow, of colors made up by the passage of a beam of white light through a prism. The various wavelengths making up the white beam are refracted to a different degree depending on the wavelength and this produces the rainbow of colors which when all mixed together give us the sensation of "white". Exhibit of Caique Parrot Photographs photographed under standard tungsten illumination and also showing the fluorescence effect when illuminated by Ultraviolet and recording the fluorescing colors through a Wratten 2E filter and the finally the reflectance of Ultraviolet when photographing the reflectance of this invisible radiation from their plumeage through a Wratten 18A filter. More Splashes! Here you will find a compilation of links to many of my photographs of water splashes. They concentrate on the after effects of the impact of a drop of water on a shallow layer of the same liquid. This is a recoil or rebound effect of the surface responding to the sudden disturbance caused by a drop of water hitting the surface. The recoil column of water rises to surprising elevations above the surface and then due to surface tension effects it breaks up into droplets that fall back into the host liquid under the pull of gravity. Panoramics and more At one time I modified a Nimslo camera by removing the septums and installing a mount for a 75mm Yashinon lens from a 21/4 Yashika camera. The resulting photographs have an aspect ratio of about 1:3 and are representative of a "poor man's" instantaneous panoramic camera. In this exhibit you will also find some strip panormaic photos also made with a home-made rotating panoramic camera. Portraits with Phoenix
