Yes, something about not having the right perspective from the camera makes it very hard to judge how close it is to the surface. I guess sometimes I get the same feeling when in an airplane landing and going over water, SFO is a good example.
This is why the trickiest landing with a floatplane is when the air is still and the water is glassy smooth. You can't tell where the surface is as you descend!
Have a little wind to make ripples in the water and your job as a pilot is much easier.
