We talked about long Usb cables a while back. Here’s what it was for. A cooking demonstration, and I’m providing an overhead shot of the prep surface. Ended up using a usb webcam from my photobooth, mounted on a photog boom over the head of the presenter. This goes back to a laptop, then to a vga splitter, and fed to 2 projectors, left/right. It turned out good and the client is very pleased. It’s fun getting a new challenge sometimes.
