[QUOTE="J-see, post: 541793, member: 31330"] Let's first come to an agreement about perspective. We use a cube to make things simple. [ATTACH=CONFIG]203098._xfImport[/ATTACH] If I had taken this shot (cube - white background) it would not matter where I stood or which lens I used to calculate the perspective of this shot. I simply follow the lines until their vanishing points and I got the perspective. That's all there is to it. And here background compression comes into play. Because the longer the focal length, the closer (or bigger) the background looks, those same perspective angles will start to differ more and more. When I use a 14mm and shoot the cube it'll appear distorted while when shooting it at 600mm it'll almost look straight. That's what compression does.
