Hey everyone A client wants me to photograph traffic intersections with the view of using the information for planning and design purposes. Snag is... They want the pictures to scale... I can see virtically down images will probably be easier to scale afterwards, if you place a known size object on the ground... Then I have to work on the angle of tall structures like lamp posts - on a previous assignment I noticed the electrical overhead line poles were all at an angle except the one absolutely directly below the camera. But where to start... Suggestions welcome!
