"PHOTOFLUX"
FLASHBULBS |
|
| |
The
modern camera-owner is making ever-increasing
use of flashbulbs.
Philips "Photoflux" bulbs
are the ideal light sources for exposures
of fast-moving subjects or candid
shots. They are indispensable for
both indoor and outdoor photography
- when there is little or no daylight
or, in bright weather, to diminish
the sharp contrast between the sun-lit
areas and dark shadows. "Photoflux"
bulbs make every camera-owner independent
of time, place, and weather. With
this never-failing aid he can be sure
that every shot turns out a winner. |

filter lacquer for colour photography. |

Designed also
for use with cameras equipped with
between-the-lens shutters, the PF
100E and PF 100E/97 flashbulbs have
a greater luminous intensity than
other "Photoflux" bulbs
and are, therefore, specially suitable
for large area coverage. They are
intended for the "open-flash"
method of photography. |

Due to their relatively long flash
duration at half peak, these types
are specifically destined to be used
with cameras with focal-plane shutters. |
