Photo fix up - distortion straightening in Light room 3

Everything has its pros and cons. Though I am not a professional in using those photo fixing programs, I still use some fix up programs like iPhoto or Lightroom. In Lightroom (LR) there are some very helpful features for you to adjust the photos like the vertical/horizontal distortion as below. If at a very quick glance, you would find the first photo a very nice vertical fix-up from the second original one. However, on a more detailed check at the hanging ad. board on the right, you would find something not in a physics logic. Supposed you should be at a 90 degree viewing angle to this photo. That means your eye level is parallel to the 3rd floor of this bldg. However, the board is upward in the photo. Furthermore, if you check on the air-conditioners, as you are on the floor higher than 1st and 2nd floor, you shouldn't see the bottom part of the air-conditioner on the 1st and 2nd floors. The above is not to say I am against photo fix-up, but just to tell how we may notice if there is any photo fix-up. Besides, the more we learn, the better we know how to distinguish. After all, I am impressed with this feature of LR. To avoid this kind of inevitable visual image fact, I should pay more attention to taking photo of some building especially with some 3D objects attached to it, better a plain 2D surface.
