INTRODUCTION
Thank you for purchasing Leeming LUT Pro™, the most accurate and professional Look
Up Tables (LUTs for your camera.
The LUTs have been carefully developed to get the maximum dynamic range and colour
accuracy out of the supported profiles, giving you unparalleled Rec709 precision as well as
perfect camera matching with other supported cameras in the Leeming LUT Pro™ range.
Use them in conjunction with ETTR shooting principles and you will get the highest
possible quality images out of the camera every time.
I am confident you will find these the most accurate LUTs for your camera. Anything less
and I wouldn't have put my name on them!

QUICK REFERENCE OF IMPORTANT CAMERA SETTINGS
The settings below are recommended for the LUTs to work properly, in conjunction with an
accurate white balance prior to applying the LUT in post.
If you deviate from these settings, your colorimetry and luma curves won’t match precisely
to Rec709 and you may get other errors in your footage. You can find the details of how to
set these in the next section.

FULL CAMERA SETUP GUIDE (Labs Firmware v . 0.70 or higher)
Based on the GoPro 12 Black with Labs firmware. Your camera may not have all the same
features so adjust as necessary. I recommend this firmware as the best option for
maximising your camera’s image quality. For normal firmware instructions, go to page 7.
1. To begin with you need to download and install the Labs firmware from this link
(instructions are included on the website :
https://gopro.github.io/labs/
2. Once your firmware has been installed, start the camera and make sure you are in
Video mode, then swipe down from the top of the screen to enter the Settings
menus. Swipe to the last page and set Controls to PRO. I usually set the Screen
Lock ON to avoid changing settings by accident, but it’s up to you.
3. Tap on Preferences, then scroll down to Video, then choose Bit Rate HIGH, Bit
Depth 10-Bit, and Anti-Flicker as needed. Exit the Preferences menu.
4. Now tap on the Video Mode button on the main screen and you’ll see Video
Presets. Tap the settings icon to the right of the profile name to enter the main
adjustments area.
5. Set Profile to Standard (this is the starting point for my Wide Gamut 400 profile to
be modified from , Aspect Ratio as desired, Resolution as desired (I recommend
5.3K when available , Frame Rate as desired (I recommend 24p for cinematic
footage . Set your Lens as desired (L+ may be greyed out depending on other
settings, I normally recommend L for a Linear image , HyperSmooth ON (note:
AutoBoost does NOT work with Labs firmware currently and will cause your clips to
be truncated and unusable .
6. In the ProTune section, set Shutter as needed (Auto is default , EV Comp to -0.5 to
protect highlight information (you can set this lower if your footage is often clipping
the whites , White Balance Auto or one of the preset temperatures, ISO Min and
Max as needed (I recommend ISO 800 as max unless you are ok with noisier
looking footage , Sharpness as desired (I strongly recommend LOW and then

adding sharpening to taste in post for better image quality , Color FLAT, RAW Audio
as needed, Wind as needed (AUTO as default , Media Mod as needed.
7. Set your On-Screen Shortcuts as desired, then Save As a Custom profile.
8. You can repeat the video settings and save more shortcut profiles if desired.
9. Set Date and Time as needed. Once finished, exit the menus.
10. Now for the Labs settings. Download the companion QR Control app for your
smartphone from the following link:
https://gopro.github.io/labs/control/
11. You can use either the app (the recommended method so you can customise your
settings , or my pre-built QR codes below, to input the settings for my Wide Gamut
log400 LUT to work properly (the best profile for the camera which gives the most
dynamic range and other customised additions . All settings below are set to
‘permanent’ where relevant so that they survive a reboot. Use them top to bottom
(excepting the choice between Shutter Auto or 180° where you should choose one
or the other to ensure the correct order of operations. Items marked in yellow are
REQUIRED for the Wide Gamut 400 LUT to work properly. Other items are
optional.
12. Simply point the camera at the QR code and you should see a QR logo with tick on
screen once it has registered the setting. Be sure to only expose one QR code at a
time to the camera, to avoid confusing the camera.
13. Note that you MUST set Wide Gamut Profile ON and Log Base 400 for my LUT to
work correctly.
Option 1: Shutter AUTO
Depth: 10bit, Bitrate: HIGH, Shutter: Auto, EV Comp: -0.5EV, White
Balance: AUTO, ISO Min: 100, ISO Max: 800, Sharpness: LOW, Color:
FLAT
Option 2: Shutter 180°
(maintains 180° shutter for cinematic footage – requires ND filters
Depth: 10bit, Bitrate: HIGH, Shutter: 180°, EV Comp: -0.5EV, White
Balance: AUTO, ISO Min: 100, ISO Max: 800, Sharpness: LOW, Color:
FLAT
WIDE Gamut Color Profile: ON

Log Base: 400
Noise Reduction: Minimum (better to handle the noise reduction in
post as the in-camera option destroys too much of the image
Maximum Shutter Speed: 1/48th (based on using 24p as your
framerate
Minimum Shutter Speed: 1/8000th
Proper 24.00p framerate: ON (useful when shooting for cinema
distribution – affects only the 24p setting
SD Card Speed Test: Run this to check how fast your card is able to
record data. Useful to ensure your card can handle the higher detail
required to handle NR off and better quality image.

Recording Bitrate: 190Mbps (check your SD card can handle the
speed using the test function above
Show ISO and Shutter Speed along the bottom of the screen: ON
Show Histogram: ON
Histogram Position and Size: Bottom Left
14. Once you have finished applying the QR codes, reboot your camera and you should
see a brief summary of applied settings on bootup, as well as the extra overlays if
you chose to add them, like histogram and ISO/Shutter info.
15. In post, be sure to apply noise reduction in the chroma range (I recommend keeping
luma noise to avoid plastic-looking images for best results from these settings.
16. To get a more contrasty image after applying the LUT, use a gentle S-curve after it,
or use one of my Pro Quickies.
17. If you have any issues with the Labs firmware, you can always flash back to the
normal firmware to remove any Labs settings.

FULL CAMERA SETUP GUIDE (Normal Firmware)
Based on the GoPro 12 Black. Your camera may not have all the same features so adjust
as necessary.
18. Start the camera and make sure you are in Video mode, then swipe down from the
top of the screen to enter the Settings menus. Swipe to the last page and set
Controls to PRO. I usually set the Screen Lock ON to avoid changing settings by
accident, but it’s up to you.

20. Now tap on the Video Mode button on the main screen and you’ll see Video
Presets. Tap the settings icon to the right of the profile name to enter the main
adjustments area.
21. Set Profile to Standard or Log (note that I have provided an HDR LUT, however I do
NOT recommend using that profile as it continuously adjusts the luma curve to fit
more dynamic range in, making a LUT for it essentially impossible. My LUT ONLY
adjusts the chroma hues for HDR and does NOT adjust luma in any way , Aspect
Ratio as desired, Resolution as desired (I recommend 5.3K when available , Frame
Rate as desired (I recommend 24p for cinematic footage . Set your Lens as desired
(L+ may be greyed out depending on other settings, I normally recommend L for a
Linear image , HyperSmooth as desired.
22. In the ProTune section, set Shutter as needed (Auto is default , EV Comp to -0.5
where available to protect highlight information (you can set this lower if your
footage is often clipping the whites , White Balance Auto or one of the preset
temperatures (although LUTs are provided for it, I DON’T recommend the Native
setting as you NEED to WB it in post prior to LUT application , ISO Min and Max as
needed (I recommend ISO 800 as max unless you are ok with noisier looking
footage , Sharpness as desired (I strongly recommend LOW and then adding
sharpening to taste in post for better image quality , Color FLAT, RAW Audio as
needed, Wind as needed (AUTO as default , Media Mod as needed.
23. Set your On-Screen Shortcuts as desired, then Save As a Custom profile.
24. You can repeat the video settings and save more shortcut profiles if desired.
25. Set Date and Time as needed. Once finished, exit the menus.
You are now ready to use Leeming LUT Pro™ with the maximum picture quality available.

HARDWARE / SOFTWARE QUIRKS AND BUGS
1. I recommend using the Labs firmware as it provides a much better Wide Gamut
colour profile along with a customisable log function, the best noise control, along
with much more. With Labs firmware the camera is truly in a class of its own in the
field of action cameras.
2. If using the normal firmware I recommend using Auto White Balance instead of
Native whenever possible.
3. The camera has a wireless connection which, if left ON, can sometimes cause the
camera to turn on automatically at random times. I recommend setting the wireless
connection OFF unless actually using the function.
4. Due to the nature of the Standard Flat and Log NATIVE white balance preset, you
MUST apply a white balance change in post-production before applying the LUT for
this profile. I recommend shooting a white balance target in the first second or so of
your clip so that you can use the WB picker function of your editing software to
quickly and accurately set this in post. The regular AWB or preset temps don’t
require it but I still recommend tweaking white balance in post and shooting a white
balance card in the initial seconds of your clip for later use in post.
5. Note that AWB can shift during the shot, so if your lighting conditions are changing
significantly, you may wish to set one of the preset temperatures to avoid this.
6. Labs firmware is currently NOT compatible with the HyperSmooth AutoBoost
stabilisation function so please use the normal HyperSmooth only, otherwise your
recordings will be truncated and unusable.
