HELP! Render is coming out mainly black and white

Looks fine in the material viewport but when I render it looks mostly black and white apart from the plants added. The metals show up just show up white and the lighting and shadowing doesn’t seem to be working properly aswell.

Not easy to tell because we don’t know you setup…

yeah, posting the file would help here. do the materials in the scene have color in them? are you sure you dont have any hidden lights in the viewport that are showing up in the render?
