Or in my case Dave, get a plant in a pot and take photos of it on the kitchen table, no damp gusset that way.
I have a periscope like device which clips over the view finder and is angled upwards.
You can keep the camera low and horizontal while you look down the attachment which is about four inches long above the camera.
I posted some photos a while back at a Morgan car rally and managed some cracking photos looking up at cars from low down.
