Abstract: A setting for white balance used by a camera during image-capturing can be reflected in a printer, thereby preventing, during printing, execution of such correction as negates an atmosphere of a light source in a recorded image in which the atmosphere has been intentionally allowed to remain. A camera used for a system of the present invention is a digital camera having a white balance process function of allowing the atmosphere of a photographing light source to remain in an image. During image-capturing, WB adaptation rate information indicative of a level of white balance correction is recorded on a recording medium as additional information. A printer reads the WB adaptation rate information for the camera via the recording medium to control white balance in accordance with the setting for the WB adaptation rate. For example, if the WB adaptation rate is less than 100%, then an AWB process executed by the printer is turned off to print the recorded image without changing its tints.
