Digital photography system and method of controlling photography
First Claim
1. A photographic system comprising a digital still camera that takes still image data of a subject through photoelectric conversion of an optical image of said subject, and an external control device that is connected to said digital still camera and is operable by an operator, wherein first exposure conditions including at least one of aperture size and shutter speed are set in said external control device by the operator, and said external control device produces second exposure conditions based on said first exposure conditions, such that said second exposure conditions stop down exposure value as compared to said first exposure conditions, and sends said second exposure conditions to said digital still camera for letting said digital still camera photograph under said second exposure conditions.

Abstract
There is disclosed a photographic system, wherein a user designates photographic conditions of a digital still camera through a graphic user interface displayed on a monitor of a personal computer. The personal computer derives second photographic conditions from the photographic conditions designated by the user, and sets up the digital still camera with the second photographic conditions. Data of a still image taken under the second photographic conditions are sent from the digital still camera to the personal computer, to be processed for gradation compression and gradation conversion. The processed still image has similar gradation to that intended by the user in most brightness range, while white-saturation in a high brightness range and black-saturation in a low brightness range are reduced.

7. A photography control method for controlling a digital still camera by use of an external control device that is operable by an operator, said digital still camera taking still image data of a subject through photoelectric conversion of an optical image of said subject, said photography control method comprising steps of:
-
setting first exposure conditions in said external control device by the operator, said first exposure conditions including at least one of aperture size and shutter speed;
producing second exposure conditions in said external control device based on said first exposure conditions such that said second exposure conditions are adjusted to stop down exposure value as compared to said first exposure conditions; and
sending said second exposure conditions to said digital still camera to let said digital still camera photograph under said second exposure conditions. - View Dependent Claims (8, 9, 10)
