Sunny16 exposure calculator 1.2.4

Sunny16 serves as an effective exposure calculator that adheres to the principles of the Sunny 16 exposure rule while offering additional functionalities. This application is particularly well-suited for photographers utilizing either film or digital cameras equipped with a manual (M) mode. It provides a straightforward tool to assist in achieving optimal exposure settings and aids in comprehending the relationships among the various elements that contribute to a well-exposed photograph.

The Sunny 16 rule operates on a simple premise: under sunny conditions, one should set the aperture to f/16 and adjust the shutter speed to match the reciprocal of the film speed. For instance, if the film speed (ISO) is set to 200, the appropriate shutter speed would be 1/200 with an aperture of f/16. However, considerations arise when altering shooting conditions, such as when using different apertures like f/8 or when shooting under varying levels of daylight. The Sunny16 app addresses these complexities with ease, allowing users to explore various settings with just a touch.

Notable features of Sunny16 include:

• Equivalent Exposures: Access a comprehensive range of equivalent exposures for any film speed under natural lighting conditions.
• Exposure Compensation: Quickly adjust exposure compensation by +/- up to 5 stops to account for backlighting or other common lighting challenges.
• Implicit Priority Modes: Set the shutter speed and subsequently change ISO, lighting conditions, or exposure compensation without affecting the chosen shutter speed; conversely, changes in aperture will retain the same shutter setting.
• Limits: If a specified shutter speed or aperture is incompatible with the selected conditions, it will not be selectable, ensuring that users remain within feasible exposure parameters.
• Stop Increment: Choose between full, half, or third-stop increments for precise adjustments.
• Lighting: Naturally occurring lighting conditions are expressed in EV 100; users can rely on descriptive indicators without needing specialized knowledge of EV.
• ISO Range: Adjustable film speeds ranging from 6 to 102400.
• Shutter Speed Range: Covering speeds from 1/16000 to 30 seconds.
• Aperture Range: From f/1 to f/32.
