Rec709 Lut
These are very useful in establishing a good base image set-up for grading a LOG footage, as you can simply focus on color having already converted the image from LOG gamma to Rec709. If your are working with RED footage in REDLogFilm, Alexa footage in LogC, or any Blackmagic footage in BMDFilm, proceed to use LOG based LUTs for contrast expansion & the color effects in one step. If you'd like more control, you can use a technical LUT to convert your LOG footage to Rec709 and then use Rec709 'look' LUTs, as this will provide a more subtle look. You can download a set of generic Rec709 to Log (technical) conversion LUTs, if you'd like to try working with your footage in true LOG but shot in standard Rec709 or if you're unable to shoot in LOG.
FLAT) you can create a LUT from it to look like a Fuji Provia? Deadcode these can be applied to any rec709 image, even with a natural profile. The colors are going to be close but not exactly the same as the Fuji ones since each camera has a unique way of responding to colors. To get exactly the same colors I would need the same image of a colorchecker with a Fuji and your LX100 with the profile that you use. Then I can do the rec709Pana-->rec709Fuji LUT, and when you apply the LUTs on the top of the page (which are actually doing the rec709Fuji-->Fancy color) and then that should be much closer to the Fuji's color.
Type of LUTs: Print LUTs that can double as Stylistic LUTs LUTs aren’t always just used to stylize footage. Sometimes they can actually be a good tool for making sure your colors are displayed accurately. This free LUT pack from Juan Melara is intended to be used to accurately export your footage for print reproduction. However, even if you don’t want to create a video for film distribution, these free LUTs can actually be used to add subtle stylization to your footage. This awesome video created by Melara shows his free LUTs in action. Notice how the colors are more subtle than the other LUTs on this list.
A LUT, for Look-Up Table, is a file (.CUBE or.3DL extension) containing math instructions to replace a color by another one. It’s like a color grading preset. If you have some questions or any troubles, please contact me at contact@iwltbap.com. I will reply you within 12h.
The good thing is that I can use the program that I wrote to compute any transformation that is needed. For example S-log/s-gammut to rec709, or slog to clog, rec709Sony to rec709Fuji etc. I only need two images from the two profiles with the same color information such as a colorchecker and of course neutral WB and same exposure.
ITU-R Recommendation BT.709, more commonly known by the abbreviations Rec. 709 or BT.709, standardizes the format of high-definition television, having 16:9 aspect ratio.

This free LUT pack is great if you’re trying to create a modern-style cinematic color grade. Melara also has a really detailed article covering how to use these LUTs to create a beautiful color grade.
Hopefully more people will download and test it for you. Dell XPS 8920 Intel i7 core 7700 build GeForce GTX 1050ti 32 Gigs of RAM 3 7200 RPM SATA Drives Windows 10 64-bit Premiere Pro CC 2017 v.11.0. Yes, a night time LUT is what I was thinking but of course I always have to turn it into a joke so I said cave. Btw I see that 2 others have downloaded this new LUT of yours, and I didn't even post in reddit yet. Doing that now. EDIT: This new LUT totally nails skin tones on indoor shoots! One other suggestion.
By applying the Arri lut, the wide gamut RGB primaries are converted into Rec709 primaries, which is what your monitor is using. This is what the Rec709 part in the LUT name refers to. Looking at the LogC documents available at, we can find the numbers we need to convert the wide gamut RGB primaries to Rec709 primaries (using a ColorMatrix node). After adjusting both the transfer function and the primaries our two images look the same*, and we have gained an understanding of how the LUTs available at Arri's website work. Now that we know why Nuke's built-in Rec709 viewing LUT won't give the expected result, let's have a look at how we could add the Arri LUT to Nuke's Viewer LUT dropdown menu. First let's remember the source and destination color-space of the LUT supplied by Arri: LogC, wide gamut RGB > Arri transfer function, Rec709. As stated earlier, all images in Nuke are stored with a linear gamma (ignoring the primaries), which means that in order to use the LUT we must first convert the linear image to LogC.
ARRI has a LUT generator that’s. RED has released a few transforms from REDlogFilm to REDgamma3 and REDgamma4, while a third party has reverse engineered the complete set and produced inverses as well, which can be.
FLAT) you can create a LUT from it to look like a Fuji Provia? Deadcode these can be applied to any rec709 image, even with a natural profile.
This is an excellent example of how lut's won't work 100% of the time. At best, they will get 95% the way there, but due to lighting changes, temperature changes, reflections, they aren't perfect. To demonstrate, I went back in, and made the lut work for indoors. I tweaked the highlights so that they rolloff differently and still maintain contrast and lowered green response.

Well, show me the well lit screen with my low light lut, jk! Btw, are you going to make any more movies? How to edit xmp files: you can make your own look that is very high quality for free! Lut creation instructions: grade inside photoshop convert video to smart object or just grade one png frame, and open as adobe camera raw, then save preset as.xmp. Then you download after generating its lut table, take that png into photoshop, apply your.xmp preset in adobe camera raw and save-as a new filename. Then open iwltap lut creator(click its question box to select 64 cube) and select the new filename.
I ended up actually reverse engineering the panasonic lut! I have attached the xmp files made in ACR in photoshop as well as the 64 cube luts. Now you can edit panasonic's offical lut(kinda) I fixed its incorrect skin tone(magenta?) and highlight rolloff(crushed) i deconflicted your camera's sensor with a new carrabean designed for it.

It gives me exactly the same result only with better black levels. And excellent skin tones! I still don't like the carribbean look. I guess after 17 years in Florida I hate all things carribbean.
Nice bokeh with that lens. So the monitor on the Inferno gives you good confidence about your exposure when shooting in V-Log L? Are you also using the waveform on the camera? Do you have a photo of your setup with the camera and Inferno for shooting out in the field? What is your white balance procedure on a rainy day like this one in the test? Thanks for the info and your examples. The Inferno has a waveform and zebra stripes and other exposure aids.
Two Ways to Grade Now let’s look at two ways of grading an image: In Diagram 1, we are taking a LogC image and viewing in a Rec709 colorspace. The final output is Rec. 709 even though no LUTs were used. This is a perfectly acceptable way of doing things but can limit what you do if you ever have to master in a larger colorspace, and if nothing else, can cost you some time if you ever have to master in another format, especially when other colorists are involved or you don’t have access to the original project files.
Exporting a graded log master By exporting a graded log master, you effectively future proof your project in the event you need to convert your project to new color spaces later on. What’s great about this workflow is that you not only save the grades, but you also save all or most of the original dynamic range in the image, which you’ll want if you are to make a transform to a colorspace that holds more dynamic range than the Rec. For example, you can already transform your final Rec 709 export to larger colorspaces, but even though the colorspace is larger, converting won’t actually bring more of the original information out of your footage. However, if you were to perform the transformation on the log master, you’d be able easily make HDR, EDR or Rec.2020 versions and access most or all of the original dynamic range and color info of the original footage. Making HDR, EDR or Rec.2020 versions Conclusion Creative LUTs can be an incredibly useful tool in your arsenal. LUTs aren’t limited to just getting you a quick grade, but can help normalize footage between two cameras.

In Diagram 2, we have a LogC to Rec709 transform LUT at the end of the pipeline, and we are making grades before (under) this LUT.
Below is an additional example with less foliage and better levels. Original footage: 709 to Log-C LUT applied: Arri Log-C to 709 LUT applied to previous shot: In this second sample you can especially notice the safer highlights as well as a little less highlight warmth and saturation (yellows in particular). Again, the LUT isn't perfect but good enough to work off of in a pinch. Installation and Use To use: • the LUT (right click save as) • Drop into Library>Application Support>Blackmagic Design>DaVinci Resolve>LUT (OSX) or ProgramData Blackmagic Design DaVinci Resolve Support LUT (Win) • Open Resolve • Add your media • Create a timeline in the Edit tab • Add the media pool file(s) into the newly created timeline • Click on the clip in the color tab • Right click the last node and select 3D LUT>LUT>BMD_to_LogC (see image below) Now your image should look nice and washed out! This LUT is released for free into the public domain. Do with it what you will!
I'm posting 50% scaled down jpeg screengrabs here, but could also send you 1080p 16bit TIFFs + the out-of-the camera DNG frame. - The first image is the 'pure' Rec709, the following images are the same image with your LUTs applied: Rec709 Astia Provia Classic Chrome Velvia. Here are some frames. Admittedly, they are extreme - because they just use a primitive color-chart based color conversion to Rec709, resulting in blown-out highlights (that I could have pulled back/recovered in Resolve). Nevertheless, you see how the overexposed areas of the image create strange blue/green banding artifacts with your Fuji LUTs.
Please sort this out, this cannot be a difficult task with all the information at hand.
I actually shot this video for HDR, and shot ETTR, but given the cloudy skies I decided there was not much point in rendering in HDR. I had a great deal of exposure latitude. AWB was used, as all the scenes were evenly lit and it looked accurate on the monitor (which also shows the VLog L with a Panasonic LUT). The camera was mounted on a tripod; I handheld the Shogun, attached by an HDMI cable to the camera.
I'll look for a low light still and get it to you shortly. Oh, btw, the latest raised blacks LUT is perfect! Both indoor and out door. EDIT: Here's the still. Oddly enough when I went to apply the latest indoor LUT, Premiere Pro crashed, but I have a feeling it was just time, not caused by the LUT. I'll continue testing.

I did some quick reverse engineering of some of the Fuji profiles and created rec709 LUTs that can achieve similar results. No Fuji camera necessary and no need to shoot with a baked-in profile! Here is an example applied to a clip from A7rII: Long story short took advantage of the fact that Lightroom allows color profiles to be used with RAW files. Then I computed the three-dimensional affine transformation that can remap the default color space from adobe to any of the Fuji profiles. I can do a much better job if I find color samples that span most of the 3D space. For this I used 4 sample images from dpreview and imaging resource. The good thing is that I can use the program that I wrote to compute any transformation that is needed.
However, seeing as they've become popular lately, I figured I'd like to share some creative uses and 'misuses' of LUTs that I've found through my work. These strategies will work whether you are grading in an NLE like Adobe Premiere Pro of Final Cut X, compositors like After Effects, and of course, color correction applications like DaVinci Resolve and Adobe Speedgrade.

LUTs can be an invaluable way to assist in exposure in camera and on set. LUTs can also improve your workflow when it comes to archival purposes as you can make a log master that includes the grade without the LUT, which is useful for making transforms to future colorspaces, or when working in collaboration with other colorists.

Rec709 Lut
In general, creative LUTs can be useful in a pinch but really aren’t something you necessarily need to spend your money on Camera manufacturer supplied conversions, such as Log to Rec. 709 These are often free and are released from each camera manufacturer for their log profiles.
However, this is not to say that it is how our eyes respond to and interpret light — only how light itself is measured. If an image is encoded in RAW (literal sensor data) or Log (a compressed and efficient encoding which gives about the same information as RAW) then it is scene referred Output referred imagery does not carry a relation to real world exposure values, meaning that it’s an interpretation of what is happening.
