take the top image and align it to match the bottom image exactly as if both photos were taken from the same camera position and angle carefully adjust perspective rotation scale lens distortion crop and framing so all major reference points line up as closely as possible including rooflines wall edges windows doors corners posts deck lines driveway edges and horizon preserve the true proportions and features of the bottom image while shifting its viewpoint to mirror the top image s vantage point do not redesign or add new elements unless already present in the bottom image this is a camera angle and composition match only the final result should look like the after photo was taken from the same exact spot height tilt and focal length as the before photo so the two images can be compared like a clean before and after overlay
