I wanted to revive this thread because I finally started shooting my posters and wanted to see if anyone's set-ups had changed or see what some of us newer guys are doing to shoot their posters? Also, Bruce, don't know if you've posted your set-up before but I'd love to see how you guys do it.
Currently, living in a condo, I have zero space for anything of a permanent workspace so I've been going for the place poster on the floor in front of a large window, put two chairs on either side of said poster, straddle the poster on the chairs and shoot from directly above. It seems to be working so far and when I pull them into editing I'm only getting minor plane distortion (not perfectly rectangular). I also don't touch the colors or brightness so I can maintain as true color to the lighting as I can. I find this is especially important for double sided posters and shooting the back side so I can see the color difference, if any.
My only concern is accidentally dropping the camera (I use the neck strap but still) or falling off the chair all together which I've almost done because my three year old tugged on my leg.
So whaddya all do? Bruce, how do you guys mass produce this process? Any and all tips are appreciated!
