The economically priced BigShot 3000 uses the same LCTF but captures the three primary colors in three flash exposures
, in less than 10 seconds, yielding a full 12-bit 48MB file.
Fortunately, digital photgraphers can review their flash exposures
on the LCD monitor while still underwater, so the learning process is many times faster than in the days of film.
The ability to record images in native RAW is retained, but the flash gains a "rear curtain sync" feature, which works wonders in balancing ambient and flash exposures
in low light.
The high-speed color negative film also offers improved response to electronic flash exposures
, as a result of Kodak's unique emulsion technology.
For many years, researchers relied on flash exposures
(tachistoscopic viewing) to uncover which package communicated faster.
The one drawback is that flash exposures
usually don't look as aesthetically pleasing as an exposure made in daylight.
From choosing equipment and understanding flash exposures
to using high-speed flash sync and duplicating the effects of available light, this is a winner for any aspiring wedding photographer.
Hurley made 20 flash exposures
, illuminating various sections of the Endurance, including her masts and rigging, while keeping the camera shutter open.
