Exponential height fog start distance issue

Hi, I’m trying to make use of the exponential height fog setting: ‘start distance’. I’d like the foreground by the camera to have less of the fog, and for the thicker fog to start further away. I’ve tried playing with this setting but nothing happens - the fog doesn’t start further away even when I put in large values.

Any tips would be much appreciated, thank you!
