How to set up Logitech MX Master 3 for Lightroom Classic

The Logitech MX Master 3 is my newest and so far the favourite mouse I have ever owned. As a long-time user of the original Logitech MX Master (after many years the scroll-wheel started acting up), the third iteration of this series feels like a big upgrade to me.

Coming in at around $100 the MX Master 3 definitely isn’t cheap a mouse. However, when compared to many high-end gaming mice, it isn’t necessarily expensive either. And the MX Master 3 has a lot to offer for creatives. I would say that $100 is probably the least you will want to pay for a mouse you’re going to end up using multiple hours a day.

The MX Master 3 is more than just hardware

However, when buying the Logitech MX Master 3, you’re not just paying for the hardware. The bundled software, Logitech Options, might be one of the best features the MX Master 3 has to offer for anyone working with creative applications such as Lightroom Classic.

My love for Logitech Options

Logitech Options offers preconfigured settings for a whole host of creative applications such as Adobe Photoshop and Premiere Pro. In most cases I found myself just sticking to whatever the default setting was. Logitech really does a good job with setting up the default profiles.

Adobe Lightroom Classic, unfortunately, isn’t one of the pre-configured applications. I did have to tinker a bit to get the thumb-wheel working the way I wanted. You might know by now that I love physical controls when working in Lightroom Classic. That’s why I have a MIDI controller hooked up to my computer. It is used for photo editing in Lightroom Classic and not for producing any music.

Adding Lightroom Classic to Logitech Options

In the main window click on All Applications and scroll down until you see the option Add application.

Scroll down to the bottom again and select Other...

A Windows Explorer window will open from which you can search for and select Adobe Lightroom Classic. The default location is:

C:\Program Files\Adobe\Adobe Lightroom Classic

You should now see Adobe Lightroom Classic as an available application in Logitech Options. Select it to edit what the individual buttons and scroll-wheels do.

Configuring Lightroom Classic in Logitech Options

I’ve assigned Redo and Undo to the two buttons on the side of the MX Master 3.

I wanted to be able to control the functions in Lightroom Classic granularly. To achieve this I selected the option Keystroke assignment.

For the turn up adjustment I entered Alt plus +. And for the turn down adjustment I entered Alt plus -.

In the develop module I can now select any of the options with a right-click and then make adjustments using the thumb-wheel.

And that’s all there is to it. With this setup, you will be able to gradually increase values in Adobe Lightroom Classic using your Logitech MX Master 3. Happy editing! And if you are interested in buying some other peripherals to go with your mouse, I have a few suggestions linked below.
