Make Adjustments in Lightroom with Physical Sliders

Lightroom adjustment sliders are nice and all, but wouldn’t it be neat if fine adjustments could be made using our hands and physical sliders rather than a mouse and virtual ones? There’s an open source program called PADDY for Lightroom that allows you to map adjustment settings in Lightroom to external devices, including MIDI faders with sliders and knobs. Here’s the description:

Paddy radically improves the workflow in Lightroom 3.0 by allowing you assign any adjustment setting – including moving the sliders and applying a preset – to keys, your number keypad, external keypads, or a MIDI controller. This gives you all editing (and some other) tools of Lightroom at the push of one button. You do not need the mouse any more to get to presets or to adjust the sliders.

The software is completely free and open source, and can be downloaded here. Sadly, it’s currently only available for Windows.

Here’s a video showing what it’s like to control Lightroom sliders with a Behringer BCF2000 B-Control Fader meant for music:

If you have a MIDI controller lying around you might want to give this a try.

    Just like a real colorist, just with less controls. Surprised this hasn’t become more mainstream already. I’ve always wanted a 3 ball rig for 3-way color correcting. I bet it’s so much easier to grade that way.

    Hope someones picks up on this and produces software for macs

    Doesn’t the Griffin PowerMate do this already?

    More interesting on a mac might be using the magic mouse or trackpad.

    this is pure awesome.

    This is supported by gimp (open source photo editor, soon in 16-bit-per-channel) since version 2.2

    It seems to me that the Powermate only has one knob and one button, where the device up top has 8 sliders, 8 knobs and about 8 buttons. I’d say the MIDI controller has a lot more productivity potential, where doing the same with powermate might require twice as much action (more clicking and dialing to switch between controls) to do the same thing.

    Dorfl68 here, key contact for Paddy. Thanks for the post. just pointing out

    1. these Midi controllers have 100+ controllers available as you can switch “presets” on the controller. So you can essentially map all LR sliders, and even have your own presets on the controller for, e.g., black&white editing
    2. paddy also has: Macros, Relative presets, LR presets mapped to keys, support for other external keyboards like the Xkeys Professional that some commercial solutions use, and much more

    It’s a DIY projects, so no guarantees or promises, but we are having lots of fun

    and yes, Gimp is an inspiration, but this is easier :-)
