Camouflage and Other Invisibility Spells

[Kekoa]

Could someone explain to me how camouflage works and how it compares to other invisibility spells? I have been attacked multiple times while camouflaged and would like to understand what the chances of being attacked are. Plus I'd like to know what all ways to be invisible are and how they differ from spell.

EDIT: Thanks for the info Estu!
