I’m curious to know how you would go about removing the colour imbalance in the scan. One side lit up with the window, the other side lit up with florescent light. It would also be interesting to know how you would get accurate colour out of the model too with the different lights in the scene.
A great breakdown non the less!
Hi Jamie,
Ideally, you’d shoot in a fully controlled lighting environment, so you can manage colour temperature. But out and about, this is not so possible. So you could shoot with a flash with a polaring filter on it. For example, with something like this: https://texxary-shop.com/products/ar400-ringflash-handles
But if you don’t have something to hand, then for any time the lighting or the temperature changes or simply every now and then for a large asset, reshoot the colour chart and then hopefully the team can grade the images as required later on.
Thanks
J
