A photography system comprising: a plurality of observation scopes each configured to be inserted into a hole of a case in which a plurality of sets of subject groups, each of which includes a plurality of subjects that are cyclically disposed around a rotary shaft and rotate around the rotary shaft, are housed along with the rotary shaft, wherein each of the plurality of sets of subject groups is housed at a different position of a shaft direction of the rotary shaft, and a plurality of holes are formed to penetrate through the case such that an angle between a predetermined direction based on the rotary shaft and a direction for each of the plurality of holes is different, each of the observation scopes being configured to sequentially acquire light from the plurality of subjects included in one set of subject groups among the plurality of sets of subject groups; an imaging section configured to continuously image light acquired by the observation scope to generate an image in a state in which the plurality of sets of subject groups rotate over 360°; a display section configured to display the image generated by the imaging section; and an image processing section configured to process an image generated by the imaging section, wherein the plurality of observation scopes are configured to be inserted into the plurality of holes in correspondence with the plurality of sets of subject groups, the imaging section is configured to simultaneously image light acquired by the plurality of observation scopes to generate a plurality of images corresponding to the plurality of sets of subject groups, and the display section is configured to simultaneously display the plurality of images, characterized in that the image processing section is configured to correct a display position of each image when the plurality of images are arranged and displayed in a direction different from a direction in which the plurality of subjects are arranged within the plurality of images based on the angle of each of the plurality of holes, the image processing section is configured to correct the display position so that a position of an image corresponding to the same position in a circumferential direction of the rotary shaft is aligned when viewed in the shaft direction of the rotary shaft, and to clip a partial image including one end part of any one of the plurality of images by an amount based on the angle and combine the clipped partial image with another end part, and the display section is configured to simultaneously arrange and display the plurality of images processed by the image processing section. a plurality of observation scopes each configured to be inserted into a hole of a case in which a plurality of sets of subject groups, each of which includes a plurality of subjects that are cyclically disposed around a rotary shaft and rotate around the rotary shaft, are housed along with the rotary shaft, wherein each of the plurality of sets of subject groups is housed at a different position of a shaft direction of the rotary shaft, and a plurality of holes are formed to penetrate through the case such that an angle between a predetermined direction based on the rotary shaft and a direction for each of the plurality of holes is different, each of the observation scopes being configured to sequentially acquire light from the plurality of subjects included in one set of subject groups among the plurality of sets of subject groups;
