Now this is a totally stupid question since I know you're shooting a different kind of camera, but what lens do you use to get all the verticals standing pretty much straight up and down?  Perhaps a better question would be "how can i do that with 35mm digital?"  Or perhaps more generically, how do you get the vertical lines to all line up perpendicular to the ground?

Hey!

   No, your question is not stupid. :D

   Keeping things straight is one of the advantage of using Field or Monorail camera. This could be done because these type of camera offer adjustment of the back or film plane and this control the perspective of the image. :D

    Yes, you could do this in digital photography also. Some photo program have perspective adjustment. :D

   BTW... very nice shot again Nathan. :D

Well, I'm not super technically-minded about this, but this is how I understand it: You can get straight lines on any camera by just keeping the film plane parallel to the subject.  Large format is different because the lens moves independently of the film.  Basically the lens is casting a great big circle of light and you are just cropping out a rectangular portion within it.  By moving the back of the camera vertically I can slide the scene up or down on the ground glass.  On a fixed lens camera you are limited by what the lens "sees" at a given distance, so if you level your camera you might not be able to get the whole building within the frame.

ooheadsoo you need to find yourself a "shift lens", dunno if there are any out there for digital but there were many produced for 35mm cameras.

I've got that Canon 24mm tilt shift and it works reasonably well. Now if it (or the other focal length versions) had a tripod mount on the lens, so the camera could be shifted, it would be the cat's pajamas.

Hey!

    Yes, this is one thing that I have to take my hat off for Canon :D I believe they are the only company who still have this specialty shift lens in their lens line up.

Hey!

   :o Well, I guess with many things are now done in digital, mostly with DSLR it is about time.  It will be expensive and not many will need this lens but for those who need this will be well served :D
