Lighting tutorial - part 1 : THE BASICS
I realized that, before making other tutorials and theories on comics’s colors, I would really need to be sure that everyone have a clear and sharp understanding of light, since it’s all connected to colors.
So, Here is the first part of it. In this one, I only talk about the basics that will be necessary to know for the other parts.
The second part will talk about the different lighting scenarios, and how they can be used to enhance narration.
The third and last part of my lighting tutorial will talk about techniques on how to easily create lighting with Photoshop.
Note that the opposite of an additive scheme is the SUBTRACTIVE scheme,
This is one of the many reasons why a colorist have to know and understand the COLOR WHEEL. There is sometimes some mathematics to perform to know if a surface will be lit or not, with or without a color shift.
For example : Does an Orange streetlight can lit a blue car on grass at night, knowing that there is no other emitter around, and the sky being very dark ?
Orange is made from RED+YELLOW. Blue is a primary color without red,yellow or orange. Green is made from BLUE+YELLOW.
Orange(Red+Yellow) * (Blue + Green(Blue+Yellow)) = Yellow.
Yellow of the grass is the only color that responds to the color cast of the Orange streetlight, so its blue part is completely desaturated and darker. It means that the car will stay dark (light having no effect on it), and that the grass will be a little bit lit, but will also look muddy, kind of brown.
When the sky turns red during a sunset, this is also because of the tiny size of the blue waves and because of the angle of penetration of the light into the sphere of the Earth, making the atmosphere thicker. The smaller balls are completely stop, and all it’s left in the color cast of the sun is Red-Orange-Purple.
To be continued....
I Hope it’ll help, Have fun !
