Re: Can this shot be salvaged?


I'm more inclined to see it as the effects of distortion inherent to the lens rather than de-centering per se.

Not sure what focal length (assuming fairly wide) these were shot at, but the swing between barrel & pincushion occurs between the 15 - 24 range. The grasses on both ends "lean in" ... as does the left side of the house. There does seem to be some variance between the left side grasses vs. the right side, but the camera isn't square to the road, so the right side grasses are slightly farther away. Barring other testing images to compare with ... I'm thinking the distortion is the main culprit here (variance @ UWA not square).

Run a straight line (thanks again, Jim) parallel to the white road stripe and it's a bit easier to see some of the curvature in play. The frame readily shows how "out of square" the camera orientation was to the roadside (i.e. grasses).
