P: Ability to use 3D LUTs

Why is there a need to start from a linear image?! Just because we need a standart, a convention to work with. We need a start point to which we calibreate out LUT so it will work every time with any camera in any image/ video editing software that support 3D LUT's and gives the same results. Just to see how a real linear image looks...

Well, generally 3D LUT's are applyed over a converted RAW file in LINEAR mode, wich is TIFF (or JPG). While Lightroom applyes pressets and setings before the raws are converted, most of raw converters out there are working with convertet tiff files in linear mode. It's a simpler way and gives good result. So the problem is that Lr work with its proprietary algoritms to convert raws and there is no way to aply a LUT before a raw file is converted, simply because Lr doesn't have the necesary tools, nor the algoritms are the same as Ps or Premiere or the softwares that convert motion picture raw's like Red or Apple. Even if Lr would allow to use Lut's they would look so much diffrent than what should they look. Lightroom should give us the option to choose how our raw files should be convertet instead of thinking that we can't understand how raws are working and how the colors are achieved. Here is so much to talk about... For instance I wasn't able to get a perfect LINEAR image out of Lightroom, simply because they are oversaturated before conversion and saturated in such a manner that low saturation colors looks undersatureted and those that are saturated result blowned up after contrast adjustmens in Ps.
This are problems that will never get fully resolved with todays Bayer sensors because RGB filters cannot be perfectly pure. I think thats why Camera raw/ Lr saturates the raw output. So we have to thak to Adobe for the amasing Ligthroom even with its flaws. Can't whait for Lr 6!
If you are interestead, you can read more information on these sites:

If it be possible to add a 3d lut files in develop module of lightroom it would be amazing! I think it would broaden the possibilities of lightroom so much, and speed up photographers workflow. Lut's from Photoshop and software like 3D Lut Creator would give it so much more editing options.

Hello! I really like the features in Lightroom and how raw files can be manipulated. Although, there are some that I personally miss, such as the ability to apply 3D LUT's and working on raw files with layer adjustments. These would very nice to see in future version of Lightroom. Thank you!

this is a great idea! Also it would be great if you could apply multiple 3D LUTs to a photograph.
