Once the optimal recording settings have been determined for each camera, the LUT is developed to bring the camera's recorded image to a standard, Rec baseline image that retains all the dynamic range while fixing any colour errors and minimising noise. This LUT is also designed to make the image feel as filmic as possible within the Rec parameters.
In other words, the intent is not only to make a proper Rec output, but have it feel closer to celluloid film than a harsh video output. Finally, the LUT is extensively tested with all sorts of different conditions, to make sure it behaves consistently and without rendering errors. If any subsequent bugs are found, the issue is fixed and updates are sent out to all owners of that LUT for free, to ensure you are always using the latest version.
I am confident you will find this the best LUT to begin your grading workflow. Anything less and I wouldn't have put my name on it! Email: leeminglutpro visceralpsyche.

I owe a special debt of gratitude to the following people for their help and assistance in developing the various LUTs here, so please be sure to support them and say thank you for their efforts!

Donate You guys asked for this, so here it is! Using the LUTs 1. Buy the appropriate LUTs for your camera s. Subtle curves and a pleasant cinematic feel, ready for delivery or as a base for further grading.
Now includes the Apollo series for brighter post-LUT images, while retaining the filmic features of the Neutral Film series. If you are using Athena LUTs these will give more subtle results. These are useful if applying the main LUTs to footage recorded on external recorders like the Atomos series which don't handle the camera level output correctly with some profiles.
Not really needed any more with the Pro and up LUTs but maintained here for backwards compatibility. Histogram - a horizontal graph showing exposure on the X axis, and the percentage of image exposed at each level on the Y axis.
False Colour - differently coloured areas depending on underlying exposure level. To understand ETTR, we need to look at digital sensors and how they work. Don't worry, I'll try to make it easy with the examples below Let's say you have an 8 bit camera, and the sensor happens to have exactly 8 stops of dynamic range for the exercise.
At the bottom stop you can only 'flip' a single bit, giving you the following eight options to describe the colour Red, for example: 0, 0, 0 Black in base10 1, 0, 0 Red in base10 0, 1, 0 Green in base10 0, 0, 1 Blue in base10 0, 1, 1 Cyan in base10 1, 1, 0 Yellow in base10 1, 0, 1 Pink in base10 1, 1, 1 White in base10 Now, the sensor-to-digital-signal conversion has to decide which of the eight potential values is the correct one. As you move up a stop, you get more possible combinations to represent your colours you can 'flip' up to two bits : Now you have slightly more values with which to describe your colour.
A Brief History The original LUT came about after Panasonic's V-Log L release for the GH4 camera was shown to be less than stellar for internal, 8 bit recording to the SD card, with visual errors like YUV chroma smearing on many flat surfaces, baseline colour shifts and reduced tonal range compared to the linear profiles.

Setup Guide PDF v - Eighteen free creative filmic looks including some basic curves and four monochrome options. With the zebras set to the recommended values for your camera from the setup guide, any overexposure will result in the zebras overlaying the affected areas, as shown here.
The big advantage over the histogram is that the zebras will show you which areas of the image are overexposed, so you can make decisions based on what parts, if any, you will let clip such as streetlights etc , and which parts need to be retained the sky, building walls etc.
As you can see, we have adjusted the brightness of our image by closing the lens iris, lowering the ISO or adjusting the shutter angle until the zebras have just disappeared, but the histogram is still ETTR. This is the sweet spot where we can get maximum dynamic range from our image with minimal noise.
This is the worst result, as it is severely underexposed and will result in a very noisy, low dynamic range image when normalised. Shadows are clipped to black and will be unrecoverable or highly noisy. If you can, raise the ISO to a higher value to help brighten the whole image so that it looks closer to one of the following histograms. This is a good ETTR exposure plot example only - your histogram will look different depending on the scene.
The histogram is biased to the right, but the highlights remain within bounds and are not clipped. In post-production it is a simple process to reduce exposure and levels back to neutral, with the advantage that noise will be much lower and tonality will be improved over shooting the same scene with a neutral histogram.
The highlights have been pushed too far to the right, to the point where they have been clipped to white. You will not be able to recover them, resulting in a lack of highlight definition and a very video-like image if the sky is the clipped portion of the shot.
