I hope I put this under the correct heading. Folks, I could use some help with this photo. I took this standing on the sidewalk. The problem is the verticals. No matter how I straighten it vertically, something is either out of plumb (e.g. the windows next to the sidewalk, the sides of the building in the back) and/or the flat roof of the back buildings is out of level. How do I fix this in order to make a believable painting? Or do I ignore the appearance of the verticals and horizontals in the photo and make them plumb and level for the painting? Any advice is appreciated.
