Export LUT Lightroom Plugin Export LUT Lightroom Plugin Version 1. These LUTs can then be used in other applications to apply the look of the preset to videos or photos. Use the plugin to apply LUTs to Lightroom photos. Download and Install Export LUT requires Lightroom 5. Restart Lightroom and you're done. The license includes unlimited upgrades. Make sure you're satisfied with the free trial before buying. One LUT will be generated for each photo or preset selected. There can be noticeable differences between 32, 64, and 100, with differences above 128 hard to discern. But keep in mind that doubling the size of the quality increases the total size of the LUT by eight, making it much slower to read into your video editor. Some video software will clumsily grind to a halt if you try to use very large sizes e. By default the LUTs will have filenames of the form presetorphoto-colorprofile-gridpoints. You can enter your own filename template using the Token dropdown menu. Preview LUT The best way to judge a LUT is to apply it to your videos or images, of course. Preview LUT will then make a virtual copy for each selected image and preset, which you may then examine and compare. The Export LUT Collection Set The Export LUT collection set contains two collections: OK to Delete: Export LUT needs to create and import temporary images to build LUTs. So you can clean up these images yourself by selecting all the images in this collection and typing Alt-Delete Windows or Option-Delete Mac. Preset Previews: Every virtual copy created by the Preview LUT command is placed in this collection, making it easy to find and delete. To delete them from your catalog, just select them and do Alt-Delete Windows or Option-Delete Mac. Assign Color Profile Use the Assign Color Profile command to assign a color profile to one or more photos. You'll be shown the currently assigned profile if any and a drop-down of color profiles installed on your computer. See for when to use this command. Limitations of LUTs Many Lightroom develop settings cannot be represented accurately by LUTs, including Shadows, Highlights, Clarity, Dehaze, Sharpening, Vignetting, and Grain. When exporting develop settings as a LUT, you will be warned if the selected photo or presets contain any of those incompatible settings, and except for Shadows and Highlights, Export LUT will ignore them when creating a LUT. Many popular Lightroom develop presets use those settings to a greater or lesser degree. In general, LUTs can only represent develop settings that transform a given input color to the same output color uniformly throughout the image. But a develop setting like Clarity can transform a given input color to many different output colors, depending on the location of pixels with that input color and the colors of nearby pixels. LUTs are incapable of representing such transformations. Mathematically, LUTs are functions mapping pixel colors to pixel colors; whereas develop settings are functions that take additional inputs, such as the location of the pixel within the image and the colors of nearby pixels. For example, a Shadows setting of +30 may lighten a given color in one image more than in another. Image-adaptiveness is why a develop setting applied to a raw may produce a slightly different effect than the same setting applied to a TIFF or JPEG exported from the raw. Since Export LUT uses TIFF test patterns, to get the best results, use non-raws JPEG, TIFF, PSD when previewing and creating LUTs. Yet another reason to avoid using raws is that Export LUT can't represent the effect of camera profiles. Some of VSCO presets use custom camera profiles and Export LUT can't reproduce the effect of the profiles since Export LUT's test pattern is a TIFF and camera profiles can only be applied to raws. Coping with the Limitations Don't use raw photos: As explained above, use non-raw photos JPEG, TIFF, PSD when previewing or creating LUTs. Use Tone Curve for large tonal changes: My experience has been that, for small and modest changes to the Basic develop settings of normally exposed photos, the exported LUT is usually fairly accurate. But for larger changes in the settings, especially with Highlights, Shadows, Whites, and Blacks, and with under- or over-exposed images, the exported LUT is less accurate due to their image-adaptive property. To make large changes to highlights, shadows, and the white and black points, use the Tone Curve panel instead — it appears that it is not image-adaptive, and thus its changes will be more accurately captured by exported LUTs. You can change the white and black points with the custom point curve. Then click the curve icon in the lower-right corner of the panel and use the Highlights, Lights, Darks, and Shadows sliders to adjust the different regions of the tone curve. However, you can apply Auto Tone or the preset containing Auto Tone to a representative image e. This takes some attention to details, since the photo and video worlds approach color management much differently. The results of applying the LUT to your video are unlikely to match the original appearance in Lightroom. Premiere Pro and Resolve assume you are viewing your video edits on a second monitor calibrated to the Rec 709 broadcast standard—neither program uses color profiles produced by your Mac or Windows calibrator i1 Display, Spyder, etc. Don't be fooled by Resolve 12. As long as you've calibrated your display, Final Cut Pro X should faithfully display video colors. Export LUT can only work with the color space Rec 709 with a gamma of 2. In Premiere Pro, it appears the timeline is always in Rec 709, with a gamma of 2. You can verify this by going to the Color Management tab in the project settings. Once assigned the correct profile, the appearance of the frame in Lightroom should match its appearance in your video editor. The Export LUT command will warn you if the selected photo is missing a color profile. Export LUT includes two color profiles, Rec 709 Gamma 2. You may have other Rec 709 profiles installed on your computer, but beware their gamma may not be apparent from their names. Color Profile for Export LUT In the Export LUT command, select the color profile corresponding to your. See for the two Rec 709 color profiles included with Export LUT. Log-Encoded Video If you are editing log-encoded video Sony S-Log, Canon C-Log, Arri Alexa LogC, etc. Resolve provides the capability of editing log video directly without converting to Rec 709, by setting the timeline to be in the color space of the log-video encoding. He refused to refund the purchase. Keyboard Shortcuts Windows: You can use the standard menu keystrokes to invoke Export LUT commands. For example, ALT+L opens the Library menu, U opens the Plug-in Extras submenu, and X invokes the Export LUT command. To reassign a different final keystroke to an Export LUT menu item, edit the file Info. Mac OS: You can use the standard mechanism for assigning application shortcuts to plugin menu commands. In Keyboard Shortcut type the desired key or key combination. Export LUT will fail with a cryptic error message on 10. Install the plugin in a folder whose path doesn't contain such characters. There's a problem with the Exiftool utility that probably won't get fixed. Try temporarily disabling Bitdefender. If that eliminates the errors, try adding the file exiftool. You can safely ignore these warnings. The plugin still may fail on Windows if installed in a folder whose path contains such characters. This was caused by a. It isn't possible to generate a LUT from a raw with an enhanced profile applied. Copyright 2015-18 John R.
