Specific Questions on Joel Greenberg

Hi Ladies,

I think I'm leaning towards Joel Greenberg right now, but I have a couple of questions.
Does joel greenberg let you keep the negatives?
Also, does he have any writing on his proofs, or are they just like regular pictures?
Does anyone know how long it generally takes him to get the negatives/proofs to you?

Also, has anyone used his studios for videography? Any price info?

THANKS SO MUCH!
