Hey, I was walking through the mall the other day, and a guy had a photo stand set up so you could get portraits done, it was a nice set up. He had his lights and such, and backgrounds, then he had his camera on a tripod, which was plugged into his iMac. When he took a picture, it showed up on his mac right away. I have a nikon d40, and am starting to get into some portrait stuff, and I use mac. Any ideas what software he was using? When i plug my camera into my mac, i cant take pictures it just allows me to transfer the photos from the camera to the computer. Any help would be apperciated.
