Hi Robert
I am a complete novice when it comes to using a flash. I did a flash photography class about 6 months ago but forgot most of that. so this time around I just goggled basic home studio and watched a bunch of youtube videos while trying different stuff. But basically I was using a D800e with a 55mm Zeiss Otus lens and using the pop up flash on the D800 as a trigger. I had one flash on a stand with a white umbrella pointing at my wife and a second flash on the floor bouncing off the celling or wall and just played with these variations until I got something that looked ok. I must say my wife was for once very patient with me fumbling around changing this and that and she had me it fits saying things like "123 Blur" meaning I would take her picture but forget to focus with the manual Otus lens
I am going to get a Strobe light when I get off the rig next month and maybe a backdrop thingie to experiment some more.
