Hey,
That does help, it was a lot of information and I thank you for taking the time to type it all out.
I probably should have clarified myself -- I'm not so much struggling with vision -- I know how I want my scenes to look in terms of color and contrast, it's just that I'm struggling with the final step, which is actually bringing my vision to life from an image in my head into a final scene that I can look at as a print.
I suppose I get intimidated by adding filters onto the camera, because without experience there's always the risk the footage will come out too red, too blue, too whatever and then you're screwed as far as post-correction goes.
I guess what intimidates me the most is that there are so many tools which can do the same job and I just don't know which to use. For example, in that little scene I showed you, you could use an amber filter of sorts on the camera itself, you could use some sort of red gels on the tungsten lights, or you could color tweak it in post to bring out the reds.
You're definitely right in saying that color schemes are more than just colored lights -- they have to do with everything, your set, your costumes, your props, etc.. but I guess what I'm more focused on is skin tones, which are by default already their own color, though in that scene for example, they're a much more deep red than you'd normally expect. That's something that doesn't come so much from painting a wall, but rather through some sort of manipulation.
So to condense myself, I suppose what I meant to ask was how do I take a vision I have in my head, with regards to color, and best choose what technical tools to use in order to bring it to life? When is the right time to use red gels for a scene like that instead of a filter? When would you do it in post? Etc.
Also, as a footnote I guess, I don't really know too much about camera filters, do you have any recommended readings I might be able to look up to learn more about them?
Thank you again. Sorry for my long posts! I just have so much I'd like to learn. ;)
