ABSTRACT:
A camera includes a taking lens and a variable aperture diaphragm adjustable to provide a relatively large aperture for effecting a relatively shallow depth of field of the taking lens and a smaller aperture for effecting a less shallow depth of field of the taking lens. Also included are manually operated means for selecting a portrait mode when taking a picture of a person and means for adjusting the diaphragm to provide the smaller aperture when the portrait mode is selected, whereby the less shallow depth of field of the taking lens is used to take a picture of a person in the portrait mode.
