Backyard shooting.

I am just doing a DVD course very basic more about teaching settings this guy is a well known photographer down under in one of his lessons he was taking early morning photos of the beach he said he wanted moving water so he used ISO 100 f22 he said f32 if your camera has it

That is so he can have a longer exposure, this way gets that silky effect to the water. I would just use an ND filter, but to each his own. This same concept doesnt translate well to moving Rabbits though...

I was referring to the loss in DR...

If ISO 100 is native to the camera, there is no loss in DR.
