New Observations of Explosive Phenomena by Submicrosecond Color Photography
Successful color photography at submicrosecond exposure times has been achieved by use of recently developed cameras, emulsions and lighting techniques. The study of explosives has been extended to include heretofore unobserved phenomena by use of the Beckman & Whitley 25-frame reimaging camera operating at exposure times of 0.12 μsec. Super Anscochrome film, force-developed for both maximum exposure index and restoration of color balance, exposed to the direct light of the explosion and the reflected light of argon-filled explosive flashlamps, produced unexpected fidelity of color, and revealed events not previously recorded with black-and-white films. An animation, produced and played back as a motion-picture sequence (shown as part of the oral paper), reveals and clarifies the motion of these newly recorded phenomena.
