The utility model discloses a foldable soft box umbrella tray, which comprises a first tray body provided with a first abutting end surface, a second tray body provided with a second abutting end surface, first cross arms and second cross arms which are movably connected with the first tray body and the second tray body respectively, and a connecting shaft which passes through the first cross arms and the second cross arms and is rotationally connected therewith. When the first tray body and the second tray body are unfolded, the first abutting end surface and the second abutting end surface are attached; and the first cross arms and the second cross arms are hidden. A soft box of the utility model can be folded into a flat shape, so that storage space is reduced, which is convenient for transportation and carrying.

A drive unit changes an irradiation direction of irradiation light from a light-emitting portion. A setting unit sets the irradiation direction of the irradiation light from the light-emitting portion. A control unit controls the drive unit. Depending on a cause of which the irradiation direction of the irradiation light from the light-emitting portion changes from the irradiation direction that is set by the setting unit, the control unit changes responsiveness of the drive unit that changes the irradiation direction of the irradiation light from the light-emitting portion into the irradiation direction that is set by the setting unit.

An illumination system for photography comprises at least a normally unlit pulsed light source (PLS) (112) with first and second electrical conduits (108, 110), a normally lit continuous light source (CLS) (300) with first and second electrical conduits (308, 310), and a hot shoe (104) with first and second electrical conduits, that is connected to a camera (100). The first conduits of all three components (112, 300, 100) are electrically connected together and the second conduits of all three components (112, 300, 100) are separately electrically connected together. When camera (100) is actuated, a switch closure from camera (100) actuates continuous light source (300), causing it to cease emitting light, and also actuates pulsed light source (112), causing it to briefly emit light, whereby both sources emit light at different times, thereby providing focus lighting while preventing light interference by CLS (300) during exposure of a subject by PLS (112).

Disclosed is a photographic lamp chuck compatible with different lamp holders. The photographic lamp chuck comprises a main chuck body (100), wherein an accessory installation position is provided on the main chuck body (100), a first insertion hole (101) for accommodating a lamp holder of a first-type photographic lamp is provided in the main chuck body (100), an arc-shaped positioning face (103) and a groove body (102) are formed in an inner wall of the first insertion hole (101), a positioning inserting member (200) is movably inserted into the groove body (102), a first positioning face is arranged on the positioning inserting member (200), a second insertion hole (202) is enclosed by the first positioning face of the positioning inserting member (200) and the inner wall of the first insertion hole (101), and the second insertion hole is used for accommodating a lamp holder of a second-type photographic lamp.

A lighting assembly includes a photographic lamp. The photographic lamp includes a lamp body, a first supporting arm and a second supporting arm. The first supporting arm is rotatably connected to a sidewall of the lamp body and capable of rotating around a rotation axis perpendicular to the sidewall of the lamp body. The second supporting arm is rotatably connected to the first supporting arm and capable of rotating around a rotation axis extending along a width direction of the first supporting arm. The rotation axis of the second supporting arm is perpendicular to the rotation axis of the first supporting arm. The second supporting arm includes a first rod and a second rod, the first rod being movable relative to the second rod to realize closing or opening of the second supporting arm.

An observation unit (30) for underwater deployment on/in a submerged earth layer (12) or structure. The unit comprises a housing (32), a light source (36), an underwater imaging device (40), a processor device (44), and a communication device (35). The housing supports the underwater observation unit relative to the submerged layer or structure. The light source is fixed to the housing, and configured to emit light into the unit's surroundings. The imaging device is attached to the housing, and configured to acquire image data of a second light source located within a FOV of the camera that covers the surroundings of the unit. The processor device is configured to determine positional data of the second light source relative to the imaging device, from the image data. The communication device is configured to transmit the positional data to another underwater observation unit, an underwater vehicle, or an underwater processing station.
