How the 'visual feel' of professional movies is obtained.
How do filmmakers give movies that visual 'movie feel'? It seems even low budget filmmakers get it right. I'm talking about the look you get that makes it seem both professional and detached, whereas a home movie, even filmed with he highest end amateur digital camera, will seem to have a more real/attached feel to it.
Is it the use of a specific type of film (e.g. beta, 35mm, etc)? Camera filters? Software filters (e.g. software to make it look like beta)? What about newer films that use HD and still get the feel?
EDIT: I've done light searching and found something about color grading, but I don't know if that's it.
