Well, I went from DFW to Miami to Jamaica, then repeated the process on the way back. I went through customes twice, once going once coming. I had my 35mm slr in my backpack allong with my digital camcorder. They told me to put it in a tray, the carried it to the other side bypassing the machine. When I got to the other side they asked that I step to the sid with them. they opened all film canisters. The took the swabs (bomb) and rubed on the straps, sides of lenses, and the shutter button. then I was free to go. Don't act shocked if they ask you to do any of this or any further steps. That will make them want to check more. Going with no film loaded is always best, but if you do have film loaded ask them if you can go ahead and rewind the film and take it out for them. We got through the inspection in about 3 minutes, and I had 10 rolls of film. If they see a traveler with that many items they ussually through 2-3 guys on inspecting yout o make it faster.
