We already know that the black and white filters can be used to see geometric layouts of a certain scene, without showing or emphasizing the colors. (i.e. where the colors are not important)
My question is is there a specific scenario where we should use sepia effect? And what is the significance of this effect to a photo?
Note: Wikipedia only gives me this piece of detail
...give a black-and-white photographic print a warmer tone and to enhance its archival qualities...
