Exposure without Meters: Sunny 16 Calc
Batteries die, but physics doesn't. The **Sunny 16 Rule** is a classic photography guideline that allows you to guess correct exposure based on the weather. The **Sunny 16 Calc** at **Online Tool Base** digitizes this knowledge, helping film photographers and manual shooters expose correctly without a light meter.
The rule calculates exposure based on the intensity of shadows. Hard shadows (Sun) mean f/16. Soft shadows (Cloudy) mean f/8. **onlinetoolbase.online** pairs this with your ISO to give you the shutter speed, keeping your film shots perfectly exposed.
Why Use This Tool?
It teaches you to "read the light." Relying on your camera's auto-meter can lead to dark images in snow or bright images in dark alleys. Sunny 16 gives you a consistent baseline incident reading, which is often more accurate for maintaining atmosphere.
Key Features
- Weather Icons: Visual selectors for Snowy, Sunny, Cloudy, Sunset.
- EV Values: Shows the Exposure Value equivalent.
- Reciprocity: Suggests equivalent pairs (e.g., f/11 @ 1/250 instead of f/16 @ 1/125).
How to Use
- Look at the sky/shadows. Select the condition.
- Enter your ISO/ASA.
- Read the target Aperture and Shutter Speed.
