Read & Expose

Let say we have a cloudy lighting situation and are shooting a ISO 200 film:

Want a shallow depth of field for shooting portraits?
→ Use f/2.8 + 1/1000s

Want a deep depth of field for landscape shots?
→ Use f/16 + 1/30s

Pro Tip: When in doubt we suggest to overexpose your image by +1 or +2 stops.

The Science Behind Our Calculator

The Sunny 16 Rule ✺

Let's talk about the magic that makes our analog film exposure calculator so reliable: the Sunny 16 Rule. This rule is the secret sauce that ensures you never waste a precious frame.

The Sunny 16 Rule is a tried-and-true method used by photographers for decades. It’s a simple yet powerful guideline that helps you achieve perfect exposure without the need for a fancy light meter. Here’s how it works:

On a bright, sunny day, set your aperture to f/16. Your shutter speed should then be the reciprocal of your film’s ISO. For example, if you’re shooting with ISO 100 film, your shutter speed should be 1/100 second. Easy, right?

But wait, there's more! The beauty of the Sunny 16 Rule is its versatility. It’s not just for sunny days; it gives you a baseline to adjust for different lighting conditions. Here’s a quick rundown:

  • Sunny Day (Sunny 16): Aperture f/16, Shutter speed 1/ISO.
  • Slight Overcast: Aperture f/11, Shutter speed 1/ISO.
  • Overcast: Aperture f/8, Shutter speed 1/ISO.
  • Heavy Overcast: Aperture f/5.6, Shutter speed 1/ISO.
  • Open Shade or Sunset: Aperture f/4, Shutter speed 1/ISO.

Our exposure calculator takes this classic rule and simplifies it even further. By aligning your film’s ISO with the current lighting condition on our calculator, you can instantly see the ideal aperture and shutter speed combination. No guesswork, no wasted frames—just perfectly exposed shots every time.

Why It Works

The Sunny 16 Rule works because it’s based on the fundamental properties of light and how it interacts with your film. It’s like having a scientific formula in your back pocket. The rule accounts for the amount of light that typically falls on a subject under various conditions, allowing you to adjust your camera settings accordingly.

In a world dominated by digital technology, our analog film exposure calculator is a breath of fresh air. It keeps you focused on the moment, without the distractions of an app or electronic light meter.
