This conversation has been merged. Please reference the main conversation: Lightroom: Ability to use 3D LUTs

With extensive LUT support in alternative RAW processors I wish Lightroom also had the ability to implement LUT color correction directly with a section of Develop module. The simpliest way as I see it is to have an option to select LUT .cube file and be able to change its overall effect on the image with a transparency or percentage slider. I can do that in Photoshop with Color Lookup adjustment layer; I'm also aware of creating a custom color profile based on a LUT with a percentage slider. The latter workaround is cumbersome and tricky.

Having a separate LUT section like Split Toning would immensely improve color correction within Lightroom. Furthermore, having the ability to load more LUTs as a stack with different effect would certainly make LR a killer app.

I'm firmly with you that LUT's should be an essential part of LR. ok, so they are yet another preset for colouring, but they are industry standard, so it would be even easier for people to make their photographs look like other peoples with LUTS.

You can use LUTs already with the Adobe Enhanced Camera Profile SDK like you  mentioned

https://spark.adobe.com/page/CEUxaoWXrcY1x/

Having them as an adjustment/tool would require parameters as well for the colorspace the LUTs operate in . I think this may add levels of complexity and room for problems with clipping, mismatched color spaces, etc. Also stacking multiple LUTs  or doing big changes with small resolution LUTs can lead to pretty nasty banding/posterization/artifacts. 

Maybe adding more intuitive color adjustment tools and the ability to possibly layer images adjustments or change the order of operations would be better. Being able to do primary and secondary corrections. Maybe some content aware mask/selection tools. Like content aware skin tone masking. Or sky. Or Foliage.

Add maybe some different interfaces for working with color. Something like this https://feedback.photoshop.com/photoshop_family/topics/interactive-gamut-masking-tool

Or look at tools like 3DLUTCreator and how they interact with color adjustments. 

Adding a 4 way color corrector (Shad/Mid/High/Offset) like DaVinci Resolve and C1 might be nice as well.

@Cameron - profiles are not LUTS' they are a way of doing something, but I can't use a LUT from PS and apply it in LR, which would incredibly useful as per the original request

Actually, you can but it takes a little more work. You can create a profile (in Camera Raw) that applies the LUT. I agree it would be easier if you had the same option in Lightroom, but it can be done already. https://improvephotography.com/53757/how-to-make-your-own-camera-raw-profiles-for-lightroom-and-came...

Ya you can. If you read the SDK I linked it even mentions Photoshop in reference to RGB LUTs.

Thanks, but, like many, I'm a photographer not a LUT creator, or a programmer, in PS, I can find the lut I want and apply it, that is what would be useful, than tinkering.
I've no time to read SKD's and work out how to do something as a work around.

Making ones own sounds interesting as well, but again I'd like
APPLY LUT option plain and simple, and I guess that is what the thread is about.

Its nice to see there is a workaround, hopefully its in LRCCC 9 / 2019.5 or whatever the next version is renamed to.

I'm not a programmer either. It's similar to making a preset in ACR/Lightroom. It's pretty simple.

You hold alt/option + click the New Preset button in Adobe Camera RAW. It brings up this dialog 


At the bottom you can see where you can select a Color Lookup Table file.  

Download the SDK and check out the PDF. It's a pretty simple short read/tutorial and includes screenshots and walks you through your first profile.

Exactly. Hamish, if you had actually read the link I gave you, you would know that it does not involve any programming skills.
