Could anyone hellp?

Hi. Just was wondering or anyone could hellp me with studio equipment?
I want to find out the name of a little mashine that flashes together with your strobes and on the wall appears picture from it, - great for the background solution if you don't have much space to work from and buy lots of different props.
Thank you a lot!

I'm guessing your are talking about a projected background. Given how easy it is to use a green backdrop and then insert the background in photoshop the projection technique is pretty much obsolete. You can do that by using a slide projector aimed at the back side of a white backdrop projecting the desired background image onto the the thin white backdrop. You have to control spill from the lights on the subject from falling onto the backdrop.

It's called a Scene Machine.

Thank you a lot!!! What would I do without this web site and people like you, guys
