LEE Stopper Exposure Guide

This is the official exposure guide for photographers using LEE Filters range of Stopper long exposure camera filters.
It's designed to help you get the most from your Big, Little and Super Stopper filters
- accurately calculating the precise exposure you require and offering a flexible timer for very long shutter speeds.

Tap the menu at the top to select your Stopper:6 Stops = Little Stopper10 Stops = Big Stopper15 Stops = Super Stopper

Turn the left hand wheel to dial in your metered shutter speed (before you insert any filters) and read the adjusted exposure on the right hand wheel.

The app converts a full range of shutter speeds in 1/3 stop increments.

Use the built-in countdown timer for any exposure over 30 seconds and see in a glance how long you have left. For very long exposures you’ll also get a reminder notification plus all countdowns finish with an alarm and a timestamp.

There’s also a handy User Guide and links to a variety of informative and inspirational web resources to support your LEE Filters Stopper photography.

Best companion to the little, big, and super stopper filters available. Especially handy since I lost the laminated guide.

When using the 10 stop option the timer disappears if you select a shutter speed greater than 1/200s. The 15 stop option works fine

The countdown timer for exposures longer than 30 seconds does not work.

The app is easy to use. I'm able to get accurate long exposures by using the app. I like it!

This is a amazing app, don't have a build in timer function in my camera so this comes in really handy!

Easy and simple to use .

So far I have very pleased with it

Thank you! Perfect:)

Really simple and easy to use. Straightforward for 6,10 and 15 stop Lee filters

Super easy to use with a built in timer so taking long exposure shots is a doddle.

Very useful. Fairly accurate and easy to use with Lee Filters.

Pretty good system. Designed for Lee Filters, but just single filter calculations available. If you use the Little & Big Stopper together, then you will need to look elsewhere for an app (they are out there). Countdown timer works well, however limited alarm sounds (most of which are annoying and play for too long). Also no vibrate alarm on this app (something which is pretty handy). Overall a good app, but I am really looking forward to the updated version soon. Lee Filters - 7.5/10 but room to make it even better, please.

This app makes taking long exposures incredibly easy! The interface is fantastic and easy to use. I just wish they would include 16 stops, since many people bought the Little and Big Stoppers.

Functions Well but Lacks Features There really aren't enough options. What if I use my 3 stop with my 6 stop? What if I use my 3 stop with my 6 stop? 10 stop with 6 stop? What if I decide to throw on a polarizer in which I know the light stoppage? Looks great, functions well but lacks key features. One could probably make a more useful and feature rich solution with Tasker app factory though it would not look as nice.

Helpful app. You do get a guide to exposure times but I find I always need a longer time than stated. Over time you get to know your camera and filter set up and can compensate accordingly. Unfortunately timer only works whilst screen is on, so I use the timer on my phone's native clock app.

It takes a lot of guess work out of using these long filters. Needed if your shutter speed is not on the help sheets as mine usually are.

Jar. S. Aug 22, 2016     

Ive looked at heaps of these apps, but this one is by far the best. So simple to use. Love it

Jas. B. Sep 18, 2016     

App crashes when using the timer for any exposure longer than a minute.

This failed to stop my friend Lee. This app must be destroyed.

Ada. E. Aug 26, 2016     

The app does everything for you

Edw. W. May 10, 2017     

Awesome App! Simple and easy to use! It would be nice to add Lee's 3 & 4 Stop filters.

A. G. u. May 6, 2017     

Finally found that works for me.

Dav. K. Aug 16, 2016     

Super simple and effective. Perfect !

Totally helpful. This app has is a godsend. I was having trouble matching up the right exposure with the card but this makes it sooooo easy.
