Leeming LUT One™ is the world's first unified, corrective Look Up Table ( LUT ) system for supported cameras, designed to maximise dynamic range, fix skin tones, remove unwanted colour casts and provide an accurate Rec709 starting point for further creative colour grading.
For single cameras, Leeming LUT One™ gives you the best possible settings to maximise dynamic range and image quality for that camera, while minimising noise and other unwanted artifacts ( like banding, YUV chroma smearing etc ). The LUT is designed for internal recording of each camera type, but works equally well with external recorders.
Multi-camera shoots become much easier, by starting with a common, colour-matched baseline, meaning much less time trying to match cameras in post before starting your creative grading.
Once all your cameras have been corrected, you can optionally use the specially matched Leeming LUT Quickies™ for a one-touch creative grade designed to work seamlessly with the common baseline of Leeming LUT One™ corrected footage.
Save hours of frustration and give your footage the best possible quality right out the gate. It's as easy as Shoot - Apply Leeming LUT One™ - Apply Quickies™ - Done!

How To Shoot Using ETTR Principles
Exposing To The Right ( ETTR ) after white balancing is the way we maximise the camera's dynamic range and tonality while minimising shadow noise. To do this successfully and efficiently, we require some visual tools to help us in camera.
The main tools to judge exposure on a video camera are, generally speaking:
- Histogram - a horizontal graph showing exposure on the X axis, and the percentage of image exposed at each level on the Y axis.
- Zebras - rolling 45° black lines over areas that exceed the set exposure level.
- False Colour - differently coloured areas depending on underlying exposure level.
On most prosumer cameras, the histogram and zebras are the only tools available, so it is these I will concentrate on.
For cameras with zebras, you can use them to easily see what parts of your image are overexposed, and adjust accordingly:
|Overexposed||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 ).|
|Exposed To The Right (ETTR)||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.|
|Neutral||Here we have lowered the brightness of the image even more, as evidenced by the histogram now showing more of a neutral curve. It trades off dynamic range and noisier shadows for an image which may not need as much grading. While this will give you acceptable results, you are not making the full use of the sensor and your images will have reduced tonality as a result.|
The following diagram shows you what to look for when using your histogram to Expose To The Right:
|Underexposed||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.|
|Exposed To The Left||Results in a very dark image. If you are shooting at night however, this may be the best your camera can do even if you are shooting wide open on your lens and at high ISO. Far from ideal but at least the black values aren't clipping. Check your ISO and iris values to see if you can make the image brighter.|
|Neutral||The whole image is exposed within the camera's dynamic range, so this would be an acceptable result if you were unable to make a brighter exposure, however it will have noisier shadows than a proper ETTR exposure. As the top stops are underutilised, you are not getting the best tonality from the image.|
|Exposed To The Right (ETTR)||This is the ideal ETTR exposure plot. 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.|
|Overexposed||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. Check to see if you can use a lower ISO setting to help minimise noise and pull back the clipped values into the legal range.|
With the histogram as a guide, you will quickly nail the correct ETTR exposure for each shot, while maximising dynamic range and minimising noise.
Between the histogram and zebras, you will be able to consistently and precisely adjust exposure to the right for each shot or scene, knowing that your images will be completely optimised for post-production, ready to apply Leeming LUT One™ and Leeming LUT Quickies™ for easy, professional results every time.
If you are interested in learning more about how ETTR works at a technical level, and why it is the right way to expose for maximum dynamic range, you can read more below.
The foundation of Leeming LUT One™ is shooting for maximum dynamic range while retaining highlight information by Exposing To The Right ( ETTR ), but not overexposing. This highlight retention is critical in making an image look filmic while minimising sensor noise, but why is it the best technique to use for video?
To understand ETTR, we need to look at digital sensors and how they work.
First, you need to adjust your brain to think in binary, not base 10! ( 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 ). So each stop uses one extra binary bit in describing each of the R G B channels, in linear space.
At the bottom stop you can only 'flip' a single bit, giving you the following eight options to describe the colour Red, for example:
00000000 00000000 00000000 ( 0, 0, 0 Black in base10 )
00000001 00000000 00000000 ( 1, 0, 0 Red in base10 )
00000000 00000001 00000000 ( 0, 1, 0 Green in base10 )
00000000 00000000 00000001 ( 0, 0, 1 Blue in base10 )
00000000 00000001 00000001 ( 0, 1, 1 Cyan in base10 )
00000001 00000001 00000000 ( 1, 1, 0 Yellow in base10 )
00000001 00000000 00000001 ( 1, 0, 1 Pink in base10 )
00000001 00000001 00000001 ( 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. If the red you see with your eyes is just a smidgen closer to green than to red, for example, the conversion might decide that the single bit it has control over should go in the Green column. But because we are at the bottom stop, it has no colour depth to be subtle, so it can only choose full-on green. We see this as a noisy, green pixel on our screens. Even if it were to pick correctly, we'd see a full-on red pixel on our screens, even if the true colour was not so saturated or bright.
So every possible colour at the bottom stop, from the billions we can see with our eyes, can only be represented with eight binary ( digital ) values. In other words, terrible colour depth and resolution.
As you move up a stop, you get more possible combinations to represent your colours (you can 'flip' up to two bits):
00000000 00000000 00000000
00000001 00000000 00000000
00000010 00000000 00000000
00000011 00000000 00000000
...and so on.
Now you have slightly more values with which to describe your colour.
As you can see though, as you go up each stop, you quickly ( and exponentially ) get a lot more possible binary combinations with which to describe your colour, meaning more colour precision ( or resolution or bit depth ) and hence, less visual noise.
The top stop ( closest to the highlights ) contains fully half of the available possible colour values, in binary ( digital ) form, because we can flip each of the 8 bits on or off for each of the R G B channels.
So for linear space digital recording, if you underexpose by even one stop compared to full ETTR principles, you are effectively throwing away half of your colour resolution ( tonality ) because those potential high resolution values are sitting idle.
Leeming LUT Quickies™
While Leeming LUT One™ will get you to a neutral, corrected colour image with a single click, many users have asked for additional, stylised looks to help get to a finished image more quickly. A one-two punch if you will, with instant results. As a way of saying thank you for buying my LUT, I have made available some Quickies™ to get you there with no muss, no fuss. These looks are designed to be used as a second node or creative effect following the application of Leeming LUT One™, and have been designed in harmony with the colour balance and dynamic range the corrective LUT provides as a first step. Full instructions for use are provided within the ZIP file itself, and there will be more Quickie™ Packs made available in the future to give you even more creative possibilities.
|Quickie™ Pack 1 (ZIP)
Quickie™ Pack 1 v2 (ZIP)
|18 free looks designed to work with Leeming LUT One's baseline corrected output matrix, retaining 100% of the dynamic range of the original clips. A larger version of the thumbnail image showing all 18 looks is included in the ZIP file, along with instructions on how to install the looks and use them with your editing software.
The v2 pack is optimised for all LUTs beginning with the number v2XX and higher.
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 4:2:0 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. The fix, after lots of testing and tweaking, was Leeming LUT One™, a superior colour and tone accurate LUT designed for the GH4's internal Cinelike-D profile, correcting the profile to a proper Rec709 colour matrix, while avoiding the need for, and issues of, V-Log L ( saving you $99 ), ready for creative grading to begin.
Now, in 2016, the LUT is being expanded to support additional cameras, providing a one stop shop for bringing all supported camera types to the same starting point for grading, while maximising each camera's internal settings to get the best dynamic range and colour tonality out of them.
The LUT Development Process
The philosophy is simple. Find the camera settings that give the best dynamic range and latitude, then develop a LUT to correct the colours to Rec709 as well as minimising colour noise, all while retaining beautiful, filmic skin tones for narrative shooting. Finally, make sure each camera's LUT output matches between them, so you can shoot different cameras and easily get to a common baseline in post with just the initial LUT application.
LUTs are specifically crafted for each individual camera. The first step in creating a LUT for a camera is to determine the best settings that maximise dynamic range, bearing in mind that the flattest profile isn't necessarily the best, if it limits the tonal range or causes errors such as banding, or YUV chroma smearing etc. Bit depth is a big factor here, as most cameras record internally using 8 bit colour depth. If there are not enough values assigned to the image ( such as the case of internal, 8 bit logarithmic recording ) then it is better to use one of the linear profiles that make full use of the available encoding bits.
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, Rec709 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 Rec709 parameters. In other words, the intent is not only to make a proper Rec709 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. Only once those tests are complete, does the LUT join the Leeming LUT One™ family. 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!
