When you shoot architecture and you want a straight photo, with no distortion, like this:
…then you need to do the following:
- Step back. Way back.
- Use a long telephoto lens.
- Do not aim up or down: keep the lens parallel to the ground.
- Consider using a tripod if the lens length is long.
You will now get an “undistorted” picture where the background is enlarged and drawn in to the subject.
