(Method of Use) Next, a method of using the small studio apparatus of the present invention will be described with reference to FIG. In the small studio device, four light sources (4a to 4d) are installed as upper light sources, three light sources (10a to 10c) are installed as lower light sources, and one light source (15a, 15b) is installed on each side light source. This will be described using an example.

A total of nine light sources are provided by the controller 2.
6 so that it can be turned on and off individually.
As shown in FIG. 7, numbers 1 to 9 are assigned to push switches of the controller 26 corresponding to each light source. FIG.
, Two lights of the side light sources 15b and 15a correspond to the push switches 1 and 2, respectively, and the upper light sources 4a, 4b and 4
Four lights d and 4c are push switches 3, 4, respectively.
5, lower light sources 10a, 10b, and 10c.
The lights correspond to the push switches 7, 8, 9 respectively.

An experienced professional photographer classifies typical subjects photographed by the small studio apparatus of the present invention into dozens of points, and performs the most ideal lighting work for each subject. In this work, 9 light sources are controlled.
The camera 26 is individually turned on and off using the camera 26 to create an optimal state for photographing. The number of the light source that is turned on at the end of shooting is recorded. Then, a set of the photographed and printed photograph and the number of the light source used at that time is filed as a lighting sample.

A person who actually shoots using the small studio apparatus refers to the above-mentioned writing sample file prepared in advance by an experienced professional photographer, and selects a file closest to the picture to be shot from among the files. . Then, the push switches of the controller 26 corresponding to the light source numbers recorded in the file are sequentially pushed.

The lighting conditions vary greatly depending on the ON / OFF of the light source corresponding to the number of the push switch, but in actual photography, no knowledge of lighting is required. Next, the characteristics of each light source will be briefly described.

The side light sources 15b and 15a corresponding to the push switches 1 and 2 are positioned as the most important main lights in configuring the lighting of the photographed product (subject). The light sources 1 and 2 are operating levers of the controller 26.
By vertically moving and rotating by a and b, it is possible to give the product a three-dimensional effect.

The upper light sources 4a, 4b, 4d, and 4c corresponding to the push switches 3, 4, 5, and 6 transmit light from the top. It is divided right and left at the back. When used together with the light sources 1 and 2, the photographed product (subject) can have a three-dimensional effect. Further, depending on the angle of photographing (overhead photographing or the like), this light source becomes the main light, and by combining it with the light sources 1 and 2, the texture of the product can be further enhanced.

The lower light sources 10a, 10b, and 10c corresponding to the push switches 7, 8, and 9 are light sources that pass through an acrylic plate serving as a photographing table from below, and are aligned with 7, 8, and 9 from the front. By using this light, the shadow of the product (subject) itself can be erased from the screen.
Also, a bottle of alcohol etc. can give a sense of transparency and the color of the liquid itself, and a glassware can give a sense of material.

Since the lighting sample file is created by a professional photographer who is familiar with the characteristics of the side light source, the upper light source, and the lower light source, even a person who has no knowledge of lighting can take a photograph to be taken from this file. If the closest file is selected, by simply pushing the push switch of the controller 26 in order, it is possible to shoot under exactly the same lighting conditions as the shooting of a professional photographer, so that the resulting photograph has almost the same quality as a professional photographer It will be.

Next, a method of using the controller 26 shown in FIG. 7 will be described. (1) First, place the controller 26 near the photographer,
The power switch e is turned on to turn on the light source generator, turntable motor, side light source drive motor, and the like. (2) Next, as described above, select the file closest to the photograph to be taken from the writing sample file,
The push switch of the controller 26 corresponding to the number of the light source recorded in the file is pushed. (3) When taking a picture with a camera for silver halide photography, since each light source is a light source that combines a strobe and a modeling light, pressing a push switch turns on the corresponding modeling light. (4) The output of the light source is adjusted using the knobs c and d. In this example, the outputs of the upper light sources 3 to 6 and the side light sources 1 and 2 are adjusted by the knob c, and the outputs of the lower light sources 7 to 9 are adjusted by the knob d. (5) When it is desired to move the side light sources 1 and 2 up and down and rotate left and right, the operation is performed by operating the operation levers a and b. (6) When the L side of the switch f is pressed, the turntable 19 rotates leftward, and when the R side is pressed, the turntable 19 rotates rightward, thereby selecting the optimal direction of the product (subject). (7) When the test switch g is pressed to confirm that the strobe emits light normally, photographing is started. When the shutter of the camera is released, the flash whose push switch is pressed emits light, and a photograph close to the selected lighting sample can be taken.

In FIG. 7, the controller 26 is connected to the main body of the small studio apparatus by a cable via a connector h, but the controller 26 has a transmission function.
The main body of the small studio device may be controlled wirelessly.
