Got it, thanks Mike.
I was in a boat, Haha. Next time I'll tell the driver to back up.
But when on foot I will keep the tip in mind. |

I used 11 x 14 film.I miss that puppy.And a better Idea of the size of that thing. Here it was with my assistant in death valley 2006 right before I sold it.One shot about $60.00 better nail it or go broke trying.LOL 25 ISO at F128. |
Blown highlights on the assistant's head. ;) |

If you want distortion free images, don't go wider than 24mm focal length,(Equivalent to 35mm on full frame), By the way, "keystoning" is where buildings taper towards the bottom,(Look at the keystone of an arch or bridge arc)your distortion is called converging verticals. |

1. For this kind of shot I usually have better results with wider lens. As example with 12-24 at 18 it looks much better that 18-55 at 18. Maybe it's because that lens is 10 x more expensive and maybe not.
2. You have to be at the half height of the subject to minimize distortion. If you don't have proper bulding, hill or a tree of that height than rent a fire truck or proper tilt&shift camera/lens. |

I'll get a batman suit and fly up there myself. Is that ok too? Or should I get a leg extension operation and get 300ft added to my legs? Or maybe call ghost busters? |

How about a whole bunch of helium balloons, like in the movie UP? You take a picture of the buildings and we'll take a picture of you. Guess which one will sell better? LOL |

The other thing to do is to use a longer lens and position yourself far enough from the building so that the distance from the camera to the bottom of the building and the distance from the camera to the top of the building are closer to being the same. |

Never be as fast as in computer though,
Too many menus, not enough grunt in the processor |
