Hey guys. Since I`ve started using the 4x5 camera, I`ve wondered how bellows work. Now that I`ve seen bag bellows, I regard it as magic. How does the light not get all scrambled up hitting the the corrugated foldings? With bag bellows this gets even more confusing, how does light not just start going all over the inside of the bag, how does it get directed onto the film? Insane.
