The shooting method of the present embodiment is a shooting method of shooting the person 200 as the subject and the background 70 with the camera 11 using the shooting system 100.
First, each component of the imaging system 100 will be described.

<Camera>
The camera 11 is a camera that takes a picture of the person 200 and the background 70. In the present embodiment, for example, an imaging optical system having an image sensor using a CCD (Charge-Coupled Device) or a CMOS (Complementary Metal-oxide Semiconductor) as an imaging device is provided. The digital camera which acquires image data by imaging | photography is illustrated. In addition, as the camera 11, you may use the silver salt film camera which exposes to a film and image | photographs.

  The camera 11 is photographed at a photographing position 10 where the camera 11 is arranged. The camera 11 may be photographed in a state where a photographer located at the photographing position 10 holds the camera 11. Or you may image | photograph in the state which fixed the camera 11 to a tripod, a crane, etc., and has arrange | positioned the camera 11 in the imaging position 10. FIG. From the viewpoint of preventing camera shake by the photographer, it is preferable to perform shooting while the camera 11 is fixed.

<Main light>
The main light 20 is a projector that irradiates the side surface of the person 200 with light. The imaging system 100 includes a top light 30 and a backlight 40 as a projector in addition to the main light 20. The main light 20 has a larger amount of light than those of the other top light 30 and backlight 40, in other words, is a projector having the largest amount of light in the photographing system 100.

  The main light 20 has a light source 21 that emits light. The main light 20 includes, as the light source 21, a stationary light emitting unit that emits light constantly and an instantaneous light emitting unit that instantaneously emits light stronger than the steady light emitting unit. Then, by operating the instantaneous light emitting unit in conjunction with the shutter operation of the camera 11 by the photographer, the instantaneous light emitting unit is controlled to emit light at the moment of shooting. Examples of the steady light emitting unit include a fluorescent lamp, a mercury lamp, an incandescent light bulb, and an LED (Light Emitting Diode). Examples of the instantaneous light emitting unit include a strobe (electronic flash).

  The main light 20 has a light box 22, and a light source 21 is provided inside the light box 22. The light box 22 is an umbrella-like structure in which a plurality of frames are combined in a substantially hemispherical shape or a substantially spherical crown shape, and the space between the frames is covered with a light shielding sheet. The light box 22 is surrounded by a distal end portion of a framework developed in a substantially hemispherical shape or a substantially spherical crown shape, and has a surface that is not covered with a light shielding sheet, and this surface emits light from the light source 21. It becomes the emission part 23. The light box 22 of the present embodiment is an octabox having eight frames and having a regular octagonal emission part 23.

  The main light 20 may or may not have a grid-like grid (not shown) in the emission part 23. The grid is a photographing instrument that is provided in a light passage between the light source 21 and the subject to improve the directivity of light. It is preferable to have a grid from the viewpoint of enhancing the contrast of light and dark of the subject. On the other hand, it is preferable that the subject is a person 200 and that the grid is not provided from the viewpoint of turning light and applying soft light to the person 200. That is, it is preferably gridless. In this embodiment, the case where the main light 20 does not have a grid is illustrated.

  The main light 20 has a diffuser 24 at the emitting portion 23. The diffuser 24 is a photographing instrument that is provided in a light passage between the light source 21 and the subject and irradiates the subject with diffused light by diffusing the light from the light source 21 that passes through the diffuser 24. This makes it difficult to produce clear shadows on the subject as compared to the light source. Light from the main light 20 is diffused light that is irradiated through the diffuser 24. Examples of the diffuser 24 include a light diffusing film using cloth, paper, a resin film or the like, or a milky white or satin-like light diffusing plate using frosted glass or a synthetic resin plate.

The position of the backlight 40 so that the aperture value (F) when the light is measured toward the backlight 40 from the position where the center line A and the background 70 intersect at the time of strobe emission of the backlight 40 is F5.6. Adjust.

  Furthermore, the first reflex plate 50 is disposed (step S106), and the second reflex plate 60 is disposed (step S107). The positions of the first reflex plate 50 and the second reflex plate 60 are adjusted so that the aperture value (F) when the light is measured from the subject position toward the main light 20 during the strobe emission of the main light 20 is F8. .

  After each component of the photographing system 100 is arranged, the subject is arranged at the subject position, and the orientation and orientation of the subject are adjusted (step S108). Here, as described above, the person 200 is seated at the subject position. Further, the head 210 and the body 220 are adjusted so as to be in a predetermined direction.

  And the person 200 and the background 70 are image | photographed with the camera 11 (step S109). In the present embodiment, the image is taken under the conditions that the exposure is 1/125 seconds, F8, the focal length of the lens is 70 mm, and the open lower limit is F2.8. The camera 11 is set at the height of the forehead of the person 200 and focuses on the eyes close to the camera 11 side of the person, that is, the left eye. FIG. 3 shows a photograph of a half body of a woman wearing a kimono, taken by this method. FIG. 3 shows a color image of a photograph obtained by photographing as a black and white (grayscale) image.

  In the above description, the case where the main light 20, the top light 30, the backlight 40, the first reflex plate 50, and the second reflex plate 60 are arranged in this order in steps S103 to S107 has been described as an example. The order of arrangement is not limited to this and may be changed as appropriate. However, from the viewpoint of balancing the amount of light from the main light 20 and the amount of light from the first and second reflex plates 50 and 60, after the main light 20 is arranged and the aperture value is confirmed, the first reflex It is preferable to arrange the plate 50 and the second reflex plate 60 to confirm the aperture value.

[3. Action and effect]
Since the photographing system 100 according to the present embodiment and the photographing method using the photographing system 100 are configured as described above, the following operations and effects can be obtained.

[1] In the photographing system 100, the main light 20 and the top light 30 having a light amount smaller than that of the main light 20 are used to irradiate the light from each of the subjects, and the first and second reflex plates 50 and 60 are provided. The reflected light from the main light 20 is reflected on the subject. The illuminance differs at each irradiation location of the subject. As described above, the main light 20 having the largest light amount can illuminate the side surface portion of the person 200 and cast a shadow on the opposite side surface portion. Further, the top light 30 illuminates the upper part of the person 200, and the first reflex plate 50 and the second reflex plate 60 illuminate the side surface opposite to the side illuminated by the main light 20 and the front surface. Accordingly, it is possible to take a photograph in which a portion that is exposed to light is highlighted, instead of darkening the entire portion where a shadow is generated without being irradiated with light from the main light 20. In this way, by combining multiple lights and a reflector board to illuminate the subject from multiple directions, the contrast between the bright and dark areas is created by the light and shadow produced on the subject. You can take pictures. Further, the backlight 40 irradiates the background 70 with light. As a result, the subject appears on the background 70 illuminated by the backlight 40, so that a photograph with a sense of depth can be taken. Still further, in the photographing system 100, photographing is performed using a predetermined plurality of equipment each having a different amount of light with respect to the subject so that light is applied to the subject from a predetermined direction. For this reason, it is possible to repeatedly take pictures with stable quality without depending on the skill of the individual photographer. Therefore, for example, even when the photographer changes or when the photographer shoots in a shooting studio different from usual, a photograph having the same quality can be taken.

[2] In the photographing system 100, the main light 20 is disposed at a position on the oblique rear side with the subject sandwiched with respect to the photographing position 10. As a result, in the subject, the side surface near the main light 20 and the back side are illuminated by the main light 20, and shadows are formed on the side surface opposite to the side surface illuminated by the main light 20 and on the near side of the subject. Can be dropped. Therefore, it is possible to take a heavy picture with a large shadow on the near side of the subject. In addition, the top light 30 is disposed obliquely above the subject and at a position opposite to the main light 20, so that light is applied to a portion that is shaded by irradiation of light from the main light 20 and emphasized. can do. In particular, when the subject is the person 200, it is possible to shoot a photograph in which the hair reflects the light and shines by irradiating the hair with light. The backlight 40 is arranged in a direction facing the position where the center line A and the background 70 intersect. As a result, the surrounding background 70 centered on the subject is brightly illuminated, and the subject is positioned in front of it, so that a photograph that gives a tight impression can be taken. Further, the first reflex plate 50 is disposed at a position opposite to the main light 20 with respect to the subject, and at a position where the length to the subject is substantially the same as that of the main light 20. As a result, the amount of reflected light reflected by the subject by the first reflex plate 50 becomes sufficient, and the portion where the reflected light is applied to the portion where the shadow is caused by the light from the main light 20 can be made to stand out. it can. Further, the second reflex plate 60 is disposed at a position that blocks direct light irradiated from the main light 20 to the photographing position 10. Thereby, it is possible to avoid a situation where the light from the main light 20 is directly incident on the camera 11 and the subject is not sufficiently exposed and the image is taken darkly. In this way, the above-mentioned actions and effects of the three light points arranged on the back side of the subject and the two point reflectors arranged on the near side of the subject are combined, thereby creating a painting-like three-dimensional image. The photograph can be taken with higher quality.

[3] The main light 20 is a surface light source in which the width of the emitting portion 23 is larger than the width of the subject. Further, the main light 20 is arranged so that the length between the main light 20 and the subject is smaller than the width of the emission part 23. As a result, a low-contrast shadow can be cast on the subject by irradiating the subject with soft light from the main light 20 that is a surface light source. Such a shadow by a surface light source is effective when it is not desired to emphasize the shadow generated on the subject. For example, when the subject is a person, the unevenness of the skin becomes inconspicuous, and the skin surface can be taken beautifully, which is preferably used.

[4] The main light 20 has a diffuser 24, and light from the main light 20 is diffused light that is irradiated through the diffuser 24. Thus, by irradiating the subject with soft light from the diffused light from the main light 20, it is possible to cast a shadow with low contrast on the subject. Such a shadow caused by diffused light is also effective when it is not desired to emphasize the shadow generated on the subject.

[5] The toplight 30 has a barn door 34 that directs light above the subject. Thus, by controlling the direction of the light from the top light 30 and directing the light intensively above the subject, it is possible to prevent the light from the top light 30 from hitting other than above the subject. Therefore, the light from the top light 30 is irradiated to the pinpoint at a portion where the light from the main light 20 does not strike, so that a photograph with a bright and dark sharpness can be taken.

[6] The backlight 40 has a barn door 44 that directs light to the background 70. Thereby, the directionality of light from the backlight 40 can be controlled to prevent light from being emitted from the backlight 40 toward the main light 20 and the subject. Therefore, it is possible to appropriately control the amount of light by the light from the main light 20 and the reflected light from the first and second reflex plates 50 and 60.

[7] Furthermore, in the photographing system 100, the subject is the person 200, the body of the person 200 faces the main light 20, and the head 210 faces the second reflex board 60. Further, the main light 20 is arranged so as to perform Rembrandt lighting by irradiating light obliquely forward and above the head 210. Thereby, on the face of the head 210, a shadow is formed on the opposite side of the main light 20 across the nose 211, and a highlight by an inverted triangular light is generated. Therefore, it is possible to take a photograph that emphasizes the three-dimensional effect and shadow of the face. In particular, when the main light 20 is at a position diagonally behind the person 200 with respect to the shooting position 10, the right cheek 212 far from the shooting position 10 becomes bright, while the left cheek near the shooting position 10. A shadow is formed on 213 and an inverted triangle is highlighted. In the case of such a so-called short Rembrandt, highlights can be generated impressively in the shadow while the area of the shadow viewed from the shooting position 10 is increased. Further, in the photographing system 100, the top light 30 can irradiate light on the hair of the head 210 where a shadow appears when viewed from the photographing position 10. Therefore, it can prevent that the hair becomes dark and melts into the dark portion of the background 70, and can be separated from the background 70 to improve the appearance. Further, the first reflex plate 50 and the second reflex plate 60 can irradiate reflected light to the left cheek 213, the back 221, and the left shoulder 223 that are shaded when viewed from the photographing position 10. Accordingly, light is applied to the left cheek 213 so that the brightness is different from that of the right cheek 212, so that brightness gradation can be generated on the face. Further, the back 221 and the left shoulder 223 can be emphasized so as not to sink into the shadow caused by the light from the main light 20. Therefore, the brightness of the light generated in the person 200 is changed, and the light is combined with the shadow in a complicated manner, so that a more magnificent photograph can be taken.

[4. Others]
In the above description, the case where the main light 20 is arranged on the left side when viewed from the shooting position 10 with respect to the center line A and the person 200 faces the left side when viewed from the shooting position 10 has been described as an example. The configuration of the photographing system 100 and the orientation of the person 200 are not limited to this, and the left and right may be reversed. For example, the main light 20 may be arranged on the right side when viewed from the shooting position 10 with respect to the center line A, and shooting may be performed with the person 200 facing the right side when viewed from the shooting position 10. In the case where the subject is a woman wearing a kimono, the kimono pattern is often arranged from the left shoulder to the left arm, so the configuration and orientation described in the embodiment are preferable.

  In the above description, the case where the main light 20 has the diffuser 24 and emits diffused light has been described as an example. The light of the main light 20 can be changed as appropriate according to the subject, and the light emitted from the light source 21 is directly emitted to the main light 20 without using the diffuser 24, so that the light is hard on the subject. Glossy light may be irradiated. In this case, by creating a dark shadow on the surface of the subject, it is possible to take a photograph that reproduces the surface condition by making the unevenness of the surface stand out.
