Why isn't Grayscale Camera Filter available in Rear Camera but it is Front?

[shanezam203]

Any idea why there are different filters on a Note 5 camera with front facing camera vs. rear? I wanted to take Black and White pictures today using "Grayscale" but it was only an option when I was using the Front Camera. Rear has "nostalgia" but I much rather prefer Grayscale with rear facing camera, any way to get this? I am trying to take Black and White photos.

Thank you,
Shane
