PS Correction For 35mm Lens Distortion? - Framed Oil Painting

[Two_In]

I fairly successfully corrected the distortion of my photograph of a framed oil painting, taken using my 35mm lens, and using PS Elements. Including the picture frame made the distortion very obvious - the painting was filling the photograph. But the method used was time consuming. I split the image in two and used Edit> Transform> Distort on each half. Did the trick ok. But is there a quicker way?

Use a flat field lens, align it properly, and there should be no distortion to "correct."

If you get your lens on the same height as the painting and centred so there is no tilt or swing in the shot you won't need to do any adjustments in post, also as Jerry says a 50mm will suffer less distortion if you can't get positioning exactly right.

If you need to do it in post I've found that it is better done on the RAW file in Lightroom as the file is lossless so the adjustments don't degrade the image like they do in PS on a JPG.
