Abstract
Abstract A boom and camera support adapted to be carried on a mobile tripod with the boom extending laterally and upwardly from said support. The boom carries a main photographic lighting device on the outer end of an arm swingingly supported at its inner end on the outer end of the boom for movement of said lighting device in an annularly extending generally horizontally disposed path about a vertically extending axis at the outer end of said boom. Said lighting device is at a uniform picture-taking lighting distance from a subject on said axis spaced below said boom. A second photographic lighting device is supported on the outer end of a second arm that is swingingly supported at its inner end for movement in an annular horizontally disposed path about a generally vertical axis at a point on said boom intermediate its ends. This device includes a fill light. A third tip light, or lighting device, at the outer end of the boom is supported on the boom for movement longitudinally of the latter outwardly thereof different distances. Said main and second lighting devices are adapted to be moved to positions at the same side of the boom, or one may be at one side and the other at the opposite side. Each of the lighting devices includes a strobe light back to back with a quartz or incandescent light directed substantially oppositely outwardly and supported for movement about an axis so the quartz lamp may be employed for television or motion pictures, or may be directed onto a sitter below the outer end of the boom for portraiture. In the latter instance the strobe lights will be directed away from the sitter against a reflector, preferably of the umbrella type to provide the picture-taking light, after the quartz or incandescent light has been turned off.

Photographic lighting apparatus comprising: a. a mobile boom support having a boom thereon extending laterally outwardly and upwardly therefrom providing an inner end at said support and an outer end spaced therefrom at a height spaced above a person to be photographed when such person is directly below said outer end; b. a first arm and a second arm; c. separate pivot means respectively supporting said first arm at one end thereof on the outer end of said boom, and supporting said second arm at one end thereof on said boom at a point intermediate said inner end and said outer end for movement of said first and second arms about their said one ends in generally horizontally disposed arcuate paths between positions projecting oppositely outwardly from said boom; d. a lighting device on each of the ends of said arms that are remote from said boom, each including electrical photographic lighting means in an electrical circuit extending to said boom support; and e. mounting means supporting each of said lighting devices for substantially universal movement relative to said arms.
Claim 2
Dependent Claim
180 words
Photographic lighting apparatus comprising: a. a mobile boom support having a boom thereon extending laterally outwardly and upwardly therefrom providing an inner end at said support and an outer end spaced therefrom at a height spaced above a person to be photographed when such person is directly below said outer end; b. a first arm and a second arm; c. separate pivot means respectively supporting said first arm at one end thereof on the outer end of said boom, and supporting said second arm at one end thereof on said boom at a point intermediate said inner end and said outer end for movement of said first and second arms about their said one ends in generally horizontally disposed arcuate paths between positions projecting oppositely outwardly from said boom; d. a lighting device on each of the ends of said arms that are remote from said boom, each including electrical photographic lighting means in an electrical circuit extending to said boom support; and e. mounting means supporting each of said lighting devices for substantially universal movement relative to said arms.
Claim 3
Dependent Claim
137 words
The apparatus as defined in claim 1, in which: f. said first arm and said second arm are supported by said pivot means for swinging across the upper side of said boom from one of said positions at an angle of approximately 90 degrees to said boom, to a position at the other side at approximately the same angle relative to the boom; g. holding means for releasably holding each of said arms stationary at any point during their said swinging from one side of the boom to the other; h. the length of said second arm being such as to support the lighting device thereon adjacent said boom support when said second arm is swung to a position extending generally longitudinally of said boom; and i. a camera support adjacent the inner end of the boom.
Claim 4
Dependent Claim
28 words
The apparatus as defined in claim 1, in which there is: f. a third lighting device carried by said boom at its outer end in said electrical circuit.
Claim 5
Dependent Claim
35 words
The apparatus as defined in claim 3, including: g. a third arm supporting said third lighting device on said boom for movement relative to said boom longitudinally thereof to different distances outwardly of the latter.
Claim 6
Dependent Claim
44 words
The apparatus as defined in claim 3, in which: f. each of said lighting devices includes a light bulb for producing a continuous light when energized and control means in said circuit for varying the intensity of the light so produced by each bulb.
Claim 7
Dependent Claim
215 words
The apparatus as defined in claim 2, including: j. means on said camera support for supporting a camera thereon for movement with said boom with its lens directed toward a sitter when the latter is positioned directly below said outer end of said boom substantially on the axis of rotation of said first arm on its pivot means whereby the lighting device on the outer end of said first arm will be at a substantially uniform distance from such sitter at all points in the path of the lighting device on said first arm during said swinging thereof; k. each of said lighting devices including a strobe light and a continuous type electrical light bulb in said circuit; l. means supporting said strobe light and said bulb in each lighting device directed oppositely outwardly for directing the light from each bulb directly on a sitter and for directing the light from said strobe light at the same time away from the sitter; and m. each lighting device further including reflector means for reflecting the light from each strobe light onto such sitter; and n. control means in said circuit for selectively energizing said bulbs during movement of said arms and for firing said strobe lights, and for de-energizing said bulbs before firing said strobe lights.
