There 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 photographs of impact of .22 cal bullet on fruit
This is a full page contact sheet of a .22 caliber supersonic bullet
fired at various fruit such as apples and lemons to demonstrate the
effect of an impact of a supersonic bullet on these subjects. The
photographs were made on Vericolor film and the action stoppig flashes
were three EG&G 549 Microflash units with a duration of less
than 1 microsecond triggered simultaneousy by a sound activated
trigger.
High Speed, Technical and Flow Visualization
Photographs:
This set of photographs includes images of a bullet's
impact on rubber bands and a lime, Schlieren photographs of warm air rising
from candles and a bullet's shock waves in air, a peripheral self-portrait and
a photograph made as the Endeavour Shuttle was taking off. This photograph was
made during a field trip I took with my students to the Kennedy Space Center in
March 1995. You'll also see wasps flying, Comet Hyakutake, a slit-scan
special effect photograph and several more "unlikely" images made with unusual
techniques or processes associated mostly with scientific and technical
photography.
Interference Colors in a Thin Soap Film
Several photographs
made of a thin film of soapy water showing interference colors. Made at close range at roughly 1/2 life
size at the camera sensor location.
More Panoramic, Peripheral, Linear and
Circular Panoramic Photographs:
A major interest of mine over the years has been the development of
improvised "strip" cameras and associated equipment and the application of this
technology for various purposes, both technical and scientific as well as
aesthetic. In this small sample you'll see a wide range of traditional and
novel applications for this mostly unknown technique.
Strip and slit-scan photographs
Several
linear strip, photofinish, panoramic of a variety of subjects made with self-made strip
camera on film. Soldiers and musicians and the K of C marching in a parade as well as a
panoramic photo in Toledo, Spain.
Vibrations visualized, Rainbow Spectral
Dispersion, Visual Illusion, and more Peripheral Portraits and other Strip Camera Photographs:
Additional high speed and stroboscopic
photographs:
Additional high speed and stroboscopic
photographs. Icluding a supersonic bullet in color schlieren beam, .22 cal bullet impact on lemon,
Barnswallows returning to nest and chicks, milk drop splash, and several stroboscopic
motion analysis photographs, etc.
A few more high speed photographs:
Additional high speed photographs of bullet impact on fruit and eggs and rubber bands.
Plus bullets ripping or burrowing through a sheet of rubber that is leftover from
exploded balloons. The material was stretched taut and pierced along the thin dimension!
Vortices in water, objects falling and in constant motion:
Photographs of magnetic stirrer induced vortices viewed from under surface,
stroboscopic photos of objects accelerating due to gravity and some subjects in constant motion.
More scientific and technical
photographs:
Including ultraviolet photographs of several flowers,
high speed sequence of bullet smashing through a lemon, reflection schlieren images of convecting chloroform,
liquid crystal thermographs and stroboscopic motion photos of children and dancers, bouncing
tennis and ping-pong balls as well as tennis ball impact on raquet, etc...
Pretty Pictures in Nature:
OK, I decided to also include some
photographs that can be described simply as "Pretty Pictures in Nature".
Landscapes, flowers, people, some splashes, snow covered landscapes, animals,
Canada geese and chicks, etc. In short, anything that I considered a
"neat" (whatever _that_ means!) image.
More Pretty Pictures in Nature:
Additional pictorial photographs such as lone trees, birds, landscapes, animals, etc..
More technical and scientific photographs:
Microscopy, high speed recording of air bubbles, polarization, stroboscopic coin toss or flip, etc.
Collection of Conical Panoramic Photographs
"rare" 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 This
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
Process:
These are six black and white photographs, 5 of which are Phoenix
Process derivations. Photograph Number 5, a Phoenix version, was made from the
Polaroid 667 paper negative that produced the "standard" Polaroid print
numbered 6.
Phoenix Process based Peripheral
Portraits:
This small exhibit of peripheral portraits is a small sample of
thousands of peripheral portraits I have made of "volunteers" at trade-shows,
conferences, demonstrations, fairs and many other events where I demonstrated
how 360 degree photographs can be made using a simple Polaroid camera slightly
modified to operate as a strip camera. The film used is Polaroid Type 667 and
the paper negatives are later further elaborated with Polaroid Polagraph 35mm
instant film prior to printing onto conventional gelatin silver photographic
materials. You can read "all" about the Phoenix Process by following the link
given below.
Phoenix Process based Figure Studies:
Once I had started to make Phoenix Process portraits it became
obvious that the technique, often showing significant levels of the Sabattier
effect, Mackie lines and a considerable (but interesting) grain pattern, could
also be applied to more traditional subject matter. In this small exhibit you
will hopefully appreciate the process's strengths as demonstrated with a
series of figure studies. You can read "all" about the Phoenix Process by choosing its title.
You can read more about many of the technical themes touched on these mini collections
by looking in my ARTICLES file.
