What is the Sunny 16 Rule? ☀️

So, What is the Sunny 16 Rule – Put simply, The Sunny 16 Rule is a photography formula designed to help you achieve a perfect exposure in sunny conditions without the need for an expensive light meter. It’s a classic rule used by photographers for decades, and it’s still highly effective today.

How to Use the Sunny 16 Rule – The Basic Formula:

• Aperture: f/16
• Shutter Speed: 1/ISO (the inverse of your film’s ISO)

For example, if you’re using Kentmere ISO 100 film, you would set your camera’s aperture to f/16 and your shutter speed to 1/100 seconds. This will give you a correctly exposed photograph when shooting in bright sunlight.

Why f/16?

The f/16 aperture setting is ideal for clear, bright light conditions because it balances depth of field and the amount of light hitting the film. It’s also a great starting point for most outdoor shots, especially when the sun is shining brightly.

How to Adjust for Different Light Conditions 🌥️🌑

While the Sunny 16 Rule works perfectly on a bright, sunny day, you might need to adjust your settings when the weather changes. Here’s how to adapt your settings to different lighting conditions:

• Cloudy or Overcast Days: Open up your aperture to f/11 or f/8, and adjust your shutter speed accordingly.
• Heavy Overcast or Shadowed Areas: Open your aperture to f/5.6 or f/4 for more light.
• Golden Hour or Sunset: Use a wider aperture like f/2.8 or f/4 to capture the soft, warm light.

By adjusting the aperture and shutter speed based on these conditions, you’ll be able to achieve the correct exposure no matter the weather.

Using the Sunny 16 Rule with the Exposure Calculator 🧮📱

To make it even easier, we’ve developed an Exposure Calculator that helps you quickly adjust your camera settings based on the Sunny 16 Rule. Simply input your ISO setting and the lighting conditions (e.g., sunny, cloudy, overcast), and the calculator will suggest the perfect combination of aperture and shutter speed for your shot.

This tool is especially useful when you’re out in the field and don’t have access to a light meter. Whether you’re walking the Thames Path or photographing a sunrise over Watership Down, the calculator ensures you always have the right settings at hand.

Why the Sunny 16 Rule Matters 🌄📷

The Sunny 16 Rule is a game-changer for photographers who prefer shooting manual film cameras. It provides a quick and reliable method for achieving perfect exposure in daylight, without relying on technology. This simplicity allows you to focus on what truly matters—capturing stunning images in beautiful locations.

Whether you’re photographing landscapes, wildlife, or urban scenes, the Sunny 16 Rule makes it easier to create balanced and well-exposed images. Plus, when combined with film photography tips and tools like the exposure calculator, you’ll have a more streamlined and enjoyable shooting experience.
