LUT research:

During editing we have been researching LUTS to use. A LUT (Lookup Table) is essentially the modifier between two images, the original image and the displayed image.

We have lots of different LUTS to experiment with to find the perfect fit for the video and give off the right feel

Some of the LUTS will not work as they amplify the wrong parts of the video's colour.
In this LUT called "Icy Blue" it amplifies the yellows from the car park floors

All the custom cuts that can be uploaded

There are about 100 different LUTS to sort through and find the perfect one that fits for the different camera angles and lighting 

Custom out can be altered

The LUTS can then be edited in FCPX, turning down the "Mix," to make the LUT less prominent

So far, this LUT, "Cine LUT 1," is the best and creates the best look for the video.
