| Pictured is the setup used for photographing glass pintype
insulators, devised by Shaun Kotlarsky (noted Hemingray specialist, see
hemingray.net), and popularized by Carol
McDougald (of Crown Jewels of the Wire fame):
- Two color-correct light boxes are
used (5,000°K, 90-92 CRI), one horizontal for bottom-lighting,
one vertical for back-lighting. These should be the only
light sources in the room!
- Insulator placed on the horizontal box
toward the back where the backlighting is strongest.
- Lens height at the centerline of the insulator.
All shots were taken using the tabletop tripod shown,
so the height was actually fixed for all insulators.
- Lens to insulator distance at least 2',
and further back for larger insulators (to reduce distortion).
Note: for maximum flatness and squareness (least distortion),
set the camera on maximum zoom, then retreat as needed in order
to frame the insulator. At full zoom, a tripod will be
required!
- Aperture f 3.5, speed 1/100.
- As always, use a self-timer and tripod:
hands off the camera when it shoots.
Camera is an Olympus C-700 (which took this pic; stunt camera shown),
chosen mostly for its 10× optical zoom (which enables pics like
this of hardware in the air).
