i just wanted to quickly put together some basic things about how i think of light and color that i think are important to be mindful of in order to make meaningful decisions about these things in your pictures. it's not going to be very fancy, but i hope its useful to somebody. im not good at writing stuff so please bear with me.
to see anything we need light. light is emitted from a emission source. after that, as i see it there are basically 3 ways light reaches your eyes
1. it is reflected off of things (such as objects)
2. it is transmitted through things (such as air)
3. it is scattered by things (such as air)
let's say we have a perfectly red ball. we know this ball is red because when we shine white light on it, red light is reflected back at us. so how does that work?
to answer that we must understand something about white light. white light is light that is made up of every color within (at least) the visible spectrum. it has red, blue, green, yellow, and so on
