Here’s an example of me looking into replicating VSCO’s Agfa Vista 400++ look. Technically we could reverse engineer the whole bunch of the VSCO, Mastin Labs and Replichrome presets that are so famous and pretty, and provide them for free as RawTherapee presets …but we’d be jerks doing so, therefore we don’t But you know, doing a reverse engineering session like this can be very educational in learning what it is that makes your favourite presets tick and then incorporate that into your own presets. It’s a long process and frustrating at times but doable. You then open the raw files in RawTherapee and try to apply settings as close to the Lightroom ones as you can then you tweak them to have your RawTherapee result match the Lightroom one as close as you can. I never quite got it just right, but produced a few variations that I like.Ģ is harder - you need sample images in raw format, edited in Lightroom. I found a great Fujifilm 400H hald that I love and have been struggling to create an actual RawTherapee preset that matches is. The downside to this is that these are as is, and can not be tweaked down the road. This doesn’t get along well with certain tools like sharpening and such, so might wanna turn them off. You then save it and it will provide you with the direct colour changes the preset applies. What you want is 1: The look of the commercial presets and 2: RawTherapee presets that match those looks, so you can tweak them.ġ is easier - you can load a blank HALD CLUT template into Lightroom and apply the desired preset. They also by default seem to apply some tone mapping, and after demosaic, further settings seem to be applied to a generated TIFF (seems like it to me, though it’s hard to prove). One of them is their demosaic algorithm, another is their highlights recovery. There are aspects of Lightroom that are proprietary, which Adobe does not want us to know how they actually work, which provide the Lightroom specific look (their secret sauce), which are not easily, or can not be replicated. LAB mode and HSV editing will also work for Luminance, Saturation and Hue changes, though I find the ones in RawTherapee are more extreme than the slider in Lightroom (so careful with them) also using a lot of them can cause noise which can be dealt with by using some noise removal. We have tools that can pretty well match the brightness/contrast/RGB curves settings you can do in Lightroom so applying a similar looking curve and settings in RawTherapee will yield a similar result (gotta look at the desired result and match the amount you need to set each slider to in RawTherapee - it’s a trial and error job that takes a while but can be done). RawTherapee is a RAW processing program, and does the same job that Lightroom was created for however due to it being written by other people via other algorithms, it does the same job slightly differently, so although you have tools that cover the same purpose, say sharpening, or demosaicing, the results may look slightly different than they will look in Lightroom. The short answer is sortof because it’s a mix between yes, in terms of some of the things we can replicate, and no, in terms of the things we can not. This is a very good question, one that I have struggled with for longer than I can remember. Is there anyway to transform/translate existing/comercially bought lightroom presets to rawtherapee?
