Ken asked the following question:
What heights do you set your tripod/monopod at? Do you shoot kitchens and bath lower or higher? Do you shoot from an average height - 5' or do you shoot higher? Do you change shooting heights throughout the property? What is a comfortable height for the viewer? Any advantages from shooting higher or lower?
Below are my camera height rules. I have to admit that I've learned most of these rules of thumb from Scott Hargis so more accurately, these are Scott's rules of thumb:
In #2 and #3 above, this means the camera will end up generally from 36" to 48" off the floor unless you have a very low bed.
The reason you typically don't have the camera above 48" is that you always have the camera leveled, ideally, with a geared three-way head. So raising or lowering the camera (as well as how wide you are shooting) controls how much of the ceiling or floor is in the image. 36" to 48" gives you about the right amount of ceiling and floor.
I'm sure others will have different points of view on this.
