For this assignment, we had to film in LOG format for a more professional finish. As preparation, I have looked into why LOG format is useful and how this affects post production with colour grading.
LOG FORMAT
To begin, LOG is favourable to professional videography due to its increased high dynamic range. Initially, through the camera monitor, the picture will look greyed and less saturated but this is in order to capture a wider range of brightness levels that can be altered to higher impact in the grade. You can more easily control the shadow and highlights, preserving the detail. Additionally, this is expanded in terms of flexibility with colour grading compared to standard video format with lower risk of over exposure. On a different note, LOG becomes more consistant across shots. This simplifies the colour grading process and creates a more cohesive vision for videographer.
Luts and camera
However, although there are many advantages to using LOG format, it requires more attention to the colour grading process. A key way of going about this is by using a LUT (Look-Up Table) which is a colour grading preset. They are coded to different brands and camera specifications so I must find one to suit my Sony A73 camera that I’ll use for the shoot. I have used the camera many times before and although it’s not the same type Chazelle would use, I can take it and try to stylise in the same way. To set up the LOG format on the camera, I must adjust the picture profile. With the coded LUT in hand for the edit, you can then alter and experiment in premiere pro to get the precise look of the film. Here, you can adjust the precise exposure, contrast, white balance and saturation, thanks to the assistance of the LOG format.
