Originally LUTs were used to compensate for different color spaces, like when going from video (YUV) to cinema (XYZ) or converting between video standards (RGB to YUV) and so on.
This was important so you could see exactly what would happen as you moved between formats.
So LUTs were used on monitors to emulate the final look.
More recently LUTs have started to be used as presets, kind of like what Magic Bullet did, which was to take ordinary footage and make it look filmic.
LOG is a great color space because it protects highlights and saturation by purposely lowering them. A LUT is used to not only restore them, but often to add a color effect, such as golden tones for late afternoon or bluish cool tones for morning.
The problem is with the Inspire, the LOG footage doesn't have a common starting point so you are flying blind. In other words, in film production they would test and adjust the lighting to match certain standards, and sometimes shoot color charts to calibrate the image before post production begins. When you do this you have a common starting point and can rely on a LUT to make the image perfect.
With the Inspire you have none of this, which is why after adding a LUT you need to fine tune the settings by eye to make them look right. |
