Imaging apparatus

An imaging apparatus comprising:

• an imaging unit configured to capture an image of a subject to generate image data;
• are operation section configured to receive a user operation;
• a memory storing information regarding a relationship between parameters including exposure values, aperture values, and shutter speed and instructions;
• and
• a controller executing the instructions stored in the memory, the instructions configuring the controller to:
• determine a target exposure value based on the image data;
• if the user operation is indicative of a predetermined function, replace a parameter input by the user to achieve the target exposure,
• if the user operation is not indicative of the predetermined function, determine one or more parameters other than that input by the user so that an effective exposure is as close as possible to the target exposure value based upon the information regarding the relationship between exposure values, aperture values, and shutter speed.
