When it comes to post-production, it's usually the visual effects artists who bring impossible characters to life that get all the attention, not the digital artists responsible for color-correction. But watching this breakdown of all the work that goes into professionally color-correcting a L'Oréal Garnier commercial will certainly have you appreciating what a Senior Colorist does—even if their work is still completely invisible to you.
If you assumed that all that went into color-correcting even a simple commercial was just adjusting a few sliders, you'll probably be shocked to see the work that Senior Colorist Andreas Brueckl at Colormeup put into this ad. In the past there has certainly been controversy about over-photoshopped models on magazine covers, but this is a different process altogether, and would be the same whether the ad featured a model, a car, or a hamburger. Everything from masking, to tracking, to layering complex corrections is used to make the lighting and colors in this ad pop and shine.
