Black and white effect

Hi everyone!

I would like to know how to add a black and white effect, but only in one camera view if possible. I would like to reproduce an old camera view.

Thank you!

You can do this with composite nodes. just drain the saturation

or edit the pic in photo shop or gimp

In the Render panels>>Format tab there’s a BW button (next to RGB, RGBA). I’ve never used it myself, but it might come in handy for you.
