Dharma Aperture Wheel | Exposure Quick Reference Chart

This is an exposure quick reference chart that allows you to quickly calculate light levels on set.

Use the same aperture value as the lens, set to normal (N).

It's also good to stick it on the back of a light meter.

It's also good to slip into your pocket.

This tool is useful for working smoothly in busy environments. The camera crew should use it as a communication tool with the lighting crew, and vice versa.

In addition to typical aperture values, we also have aperture values in between.

The values between multiples and fractions are also clearly indicated, so you can rest assured.

It is designed to quickly adapt to the EL zone, which is expected to replace false color in the future.

By displaying a color scheme specified for each stop,

It's also easy to communicate with the chief cameraman and lighting technician who are monitoring the footage.

[How to use]

Rotate the wheel to match the lens aperture value, setting it to "N". Use the light meter to measure the key light, fill light, or the incident light in the bright and dark areas.

Check the value displayed on the light meter with the wheel to see how many times, or how many times, the amount of light is relative to the aperture value.

You can see the ratios in lighting (lighting ratio / contrast ratio) at a glance.
