A camera is provided with a photographing device for setting various photographing conditions which determine a state of a subject image to be obtained as a picture, the photography device including an exposure device having a plurality of selectively settable exposure modes for automatically setting at least one exposure value based on brightness of a subject, a mode selector for selecting one of the plurality of exposure modes, a calculation unit for calculating an amount indicative of the state of the subject image in accordance with the photographing conditions set by the photography device, an estimation unit for estimating visual effects which the subject image provides based on the calculated state amount, and a display device for displaying the visual effect corresponding to the exposure mode selected by the mode selection means in accordance with the estimated visual effects. Accordingly, an operator of the camera is allowed to conceive before an exposing operation what the final picture will look like in accordance with the photographing conditions set in a variety of exposure modes.

Camera capable of displaying the level of visual effect

A camera system includes a camera device and a flash device. The camera device has a first mode where a control aperture value and a control shutter speed are automatically determined; and a second mode where the operator is allowed to determine either a control aperture value or a control shutter speed. The flash device is capable of emitting an instantaneous flash light and a prolonged flash light. The camera device includes a distance calculator operable to calculate a distance to an object and a light intensity calculator operable to calculate an intensity of a prolonged flash light for flash photography based on the calculated distance, a focal plane shutter having a front blind and a rear blind, and a controller operable to render the flash device emit a prolonged flash light at the calculated intensity from the start of travel of the front blind to the finish of travel of the rear blind.
