All-weather built-in cameras have also been put into practical use, and underwater strobe photography has become possible with such cameras. When using a conventional camera of this kind underwater, the optical axis of the camera's photographing lens and the light emitted from the strobe light emitter are close and parallel.
This has the disadvantage that the strobe light causes scattering by objects floating in the water up to the subject, and this scatters onto the film, resulting in photographs with weak contrast.

However, when using this camera system on land, the camera body does not have a built-in strobe, so it is difficult to use a camera with a built-in strobe. ) is also inconvenient.Of course, if a camera with a built-in strobe is equipped with a device that moves the strobe light emitting part far enough away from the optical axis, it can be used for underwater photography, but doing so would require a large-scale device. This makes it inconvenient for normal land photography.

For underwater photography, the camera's built-in strobe's power supply and circuitry can be used to light the underwater photography light emitting section, allowing the strobe to be emitted at a location separated from the camera beam. The built-in strobe of this camera can be used for land strobe photography, and it can also be used as an underwater strobe light emitting unit. Hereinafter, the present invention will be explained in detail with reference to the drawings.

Figure 3 is a circuit connection diagram showing an embodiment of the strobe device for a amphibious camera according to the present invention. In Figure 3, Xe is built into the camera body. In the strobe device, 1 and Xv are strobe light emitting units for underwater photography. The internal strobe device Xe is composed of a power supply battery E, a strobe switch S, a main capacitor CM e , a rigger capacitor KCT, a step-up transformer Tr, a built-in flash discharge tube X1, and the like. S is the trigger switch, which is the X contact of the camera's shutter release, and No. 8 is the switch that disables the flash discharge tube x1. CN is the connector and the first
As shown in FIG.
By installing the flash discharge tube X, the flash discharge tube X is installed and controlled.

After charging is complete, turn on the switch S using the shutter's X contact, and the internal flash discharge tube Connect the connector CN' of the strobe light emitting unit Xw, and turn off the switch Sm on the camera side. In this state, turn on the strobe switch S and charge the strobe as you would for land strobe photography.
When the shutter release is completed and the switch S is turned on, the flash r tube X of the underwater photography strobe Xv is released.
emits light. At this time, the camera built-in strobe discharge tube X does not emit light because the switch S is turned off.

If you do this, the built-in flash discharge tube X and the underwater photography flash discharge tube X can be synchronized with the shutter release and emit light at the same time, allowing you to take strobe photography with effective light distribution. . Of course, even in land photography, it is possible to make only the flash discharge tube X for underwater photography emit light.
