LEE Filters - Stopper Exposure 1.4.2

This is the official exposure guide for photographers using LEE Filters range of Stopper long exposure camera filters. It aims to assist photographers in maximizing the potential of their Big, Little, and Super Stopper filters by accurately calculating the required exposure and offering a customizable timer for extended shutter speeds.

Choose your Stopper by selecting from the menu:

• 6 Stops = Little Stopper
• 10 Stops = Big Stopper
• 15 Stops = Super Stopper

Adjust your metered shutter speed using the left-hand wheel (prior to inserting any filters) and receive the adjusted exposure reading on the right-hand wheel. The app supports conversions for a comprehensive range of shutter speeds in 1/3 stop increments.

Utilize the integrated countdown timer for exposures exceeding 5 seconds and easily monitor the remaining time at a glance. In cases of very prolonged exposures, a reminder notification, as well as an alarm and timestamp upon countdown completion, ensure accuracy.

Additionally, access a convenient User Guide and discover various informative and inspirational online resources to enhance your Stopper photography experience.
