The level of saturation should also be used to effect, when life and energy needs to be emphasised the colours can be saturated, in turn desaturated colours can make the image feel gloomy and dull which can be used to describe more sombre moments.
This specific task is to describe the same scene at different times of day, as an exercise it can be a good way to experiment with potential directions for a shot when the lighting is not already fixed. I chose to develop a shot from my previous thumbnail sheet, I intentionally chose a simpler shot that I would not develop beyond this exercise as I wanted to focus on the task of accurately colour keying the times of day as opposed to getting stuck on design elements.
The times of day I looked at were morning where the sky has a cooler colour with a warm light, creating below average saturation. Afternoon, with a more saturated, darker sky, offset with a hazy horizon to emphasize atmospheric perspective. Finally, I went for night as with my final project direction I will most likely have a lot of shots at night, it was emphasised that the sky should always be saturated as opposed to the ground being desaturated due to the lack of natural light.
The grey scale frame shows the shot template, layers were set up for all aspects, some elements had several layers, for example the car had layers for the paint on the front and rear sections, a layer for the chrome and the glass. For more elaborate shots the layer set up will be the most time consuming aspect, this is also key to the success of the piece as you are 'locking' the design at this stage. Layers are used as a selection point for each object or sub object, when everything is cleanly separated into layers the rendering process is optimised.
