简介
The Sunny 16 rule is a handy rule of thumb in outdoor daylight photography; the rule estimates the required daylight Exposure Value without using a light meter.
This rule evolves around three concepts:
1) Incident light (as opposed to reflected light); an advantage for `difficult' subjects
2) The different lighting conditions in outdoor photography (sunny, slight overcast, overcast, heavy overcast, and open shade/sunset)
3) The relatively fixed exposure value for daylight under these conditions
What the rule does NOT prescribe are the actual camera settings (aperture, ISO and shutter speed) that you can use, as long as the combination of manual camera settings lead to an equivalent exposure value as specified by the rule.
And this is exactly where the Sunny 16 Calculator app comes in: it lets you
a) change settings for aperture, ISO and shutter speed, and
b) use ND-filters for which the filter density (the filter exposure compensation value) can be taken into account,
c) balance out all these settings to achieve a correct exposure in accordance with Sunny 16. The calculator supports the balancing process by indicating the resulting overall exposure value in stops RELATIVE to the rule for a selected lighting condition, taking into account a selected filter density.
The calculator can also be used as a `training device', where you first guess the required combination of settings for balance, and subsequently check these with the calculator.
Explanation for the calculator screen, from top to bottom:
A) Select a lighting condition. Based on the lighting condition, the calculator automatically selects the aperture, ISO and shutter speed in accordance with the Sunny 16 rule.
B) The number display indicates whether the selected settings are in balance (indicated by 0), or whether a correction in the settings is necessary (indicated by a negative number for under exposure, of a positive number for over exposure)
C) If you want to change settings for aperture, ISO, shutter speed or filter density, you can select this in the switch just below the number display. Of course changing settings will lead to the number display increasing or decreasing; this exposure offset needs to be balanced out by using (a combination of) the other settings, until the displayed number becomes 0 again. The switch itself continuously displays the selected values for aperture, ISO, shutter speed and filter density.
D) The circular controls for aperture, ISO, shutter speed or filter density are displayed below (when the screen is in ‘portrait mode’) or to the right (in ‘landscape mode’). You can change the settings for the circular control either by tapping on the control or by moving the pointer.

版本 3.0
Version 3
1. Maintains aperture, ISO, shutter speed and filter density settings when (a) changing the lighting condition, or (b) consulting the info screen. Changing the lighting condition only affects the overall exposure balance value.
2. Incorporates a separate ‘Filter’ dial. This dial lets you set a filter density (filter exposure compensation value), to be taken into account in the exposure balancing. The values on this scale increase counter-clockwise because of their negative effect on the exposure balance.
3. Extends the range of the shutter speed dial up to two minutes (nominal), in order to allow for strong ND-filters.
4. Includes Light, Dark, and Tinted app icon variations.
