Abstract
The invention provides a wearable device, such as a watch, that provides a way to calculate an appropriate camera shutter speed and aperture setting for a given ISO speed setting to obtain settings that, when entered into a camera, will result in an appropriate photographic exposure. The devices of the invention provide a simple, fast, convenient way to calculate appropriate settings for the components of the photographic exposure triangle.
Claims18
A watch for calculating photographic exposures, the watch comprising:
- a) a watch case;
- b) a watch face disposed in the watch case, wherein the watch face is visible through an opening in the watch case;
- and
- c) a rotatable bezel attached to the watch case such that the bezel is capable of moving in axial rotation about the watch face;
- wherein either:
- i) the watch face comprises:
- 1) a plurality of markings that correspond to camera aperture numbers;
- and
- 2) at least a first ISO speed reference indicator that corresponds to a first ISO speed setting;
- and the rotatable bezel comprises:
- 3) an aperture reference indicator;
- and
- 4) at least a first plurality of markings that correspond to camera shutter speed values;
- or
- ii) the watch face comprises:
- 1) an aperture reference indicator;
- and
- 2) at least a first plurality of markings that correspond to a first plurality of camera shutter speed values;
- and the rotatable bezel comprises:
- 3) a plurality of markings that correspond to camera aperture numbers;
- and
- 4) at least a first ISO speed reference indicator that corresponds to a first ISO speed setting;
- wherein the markings that correspond to the aperture numbers, the shutter speed values, the aperture reference indicator, and the first ISO speed reference indicator are arranged such that when the rotatable bezel is rotated to place the aperture reference indicator adjacent to a particular aperture number, the first ISO speed reference indicator adjacent to an indicated shutter speed value, wherein when the indicated shutter speed value, the particular aperture number and the first ISO speed setting are set in a camera, a photograph taken by the camera will have an appropriate exposure.
