P: Ability to use 3D LUTs

would love to see 3dlut cube files used with light room! please make it happen

"Yes they have, it's in the SDK Documentation."

Adobe has documented the format of .cubes loaded into the New Profile window of Camera Raw, but they haven't documented the format of the LUT as it is actually stored in the .xmp file containing the enhanced profile.  It is this latter format that's needed for plugins to be able to construct LUT-containing enhanced profiles from LUTs in color spaces like Rec 709 that Adobe has chosen not to provide.   See the discussion in the other topic for more details:

Yes they have, it's in the SDK Documentation. There's more info in the SDK as well as a sample LUT. It's an Iridas/Adobe Format Cube LUT with no blank lines in the header.

Unfortunately, it isn't possible for a LR plugin to make up for the missing ability to use Rec 709 LUTs, because Adobe hasn't documented the format of LUTs used in enhanced profiles.   Please add your vote to this feature request:

Haha, my bad! I read it in my email and missed the link! *me-too'd

I think you missed the link at the end of my last post.

Should probably make a new topic for this and post it here?

LR 7.3 and ACR 10.3 just added "enhanced profiles", which include the ability to specify a LUT to be used in the profile.  This lets you apply LUTs in LR faster than using my Apply LUT plugin, without the need to create a TIFF for the result.

Unfortunately, there are two problems standing in the way:

1. You need to create the LUT profile in Photoshop / ACR, not LR.

2. ACR doesn't let you specify Rec 709 as the color space of the LUT. Rec 709 is the most common color space of LUTs used in video editing. When people say they "want to use LUTs", they're typically referring to all the widely used Rec 709 video-editing LUTs.

The former is an inconvenience, the latter is a roadblock. Please add your me-too vote to this feature request:

I need any app for applying presets to images in Android.
Because rebuilding Lightroom app with my desired presets is crashing the app.

I've just released Apply LUT, a plugin that applies 3D LUTs to photos in Lightroom. If you try it, please let me know how well it works for you (or doesn't).
