Hi Everyone,
Is the window in the middle distorted? I am trying to figure out what i shoudl change if anything about this photo. Is the best way to change it though the distortion filter in photoshop?
Any attempt to remove the distortion will also result in a reduced field of view, and in any case other than being crooked there's nothing wrong with it.
You need to use keystoning to reduce the vertical perspective. Below I have done it for you. Notice how the vertical lines are now vertical, and don't exhibit 3-point perspective? It's you're choice which one looks better.
