How do I regain image appearance after perspective adjustment?

I've struggled with this for years and have finally decided to ask here.

I improve perspective in many pictures. It always distorts the subject. I try to return the subject to its original appearance but do it by eye and am often unsatisfied with the result.

The two images attached are before and after versions of the same image. The first is as it came from the camera, the second is after perspective adjustment. The statue is obviously stretched vertically in the adjusted image.

The whole idea is that to maintain proportions, you have to drag partly inwards, partly outwards. The line should cross the image frame at the halfway point.

To avoid upsampling, you can first convert to a smart object, and then after perspective, scale down the whole image to fit within the original frame.

You can go too far as well. The marble lady appeared to have lost a lot of weight in the OP's second screen shot.

I've got rid of the document I was playing with the image with, but adding to your advice Dag, I dragged out a bunch of guides to both help align the verticles to, but also to maintain proportions like where the top of the stone lady's head should be. Things can move all over the place when radically adjusting perspective. I still found that Camera RAW did a better job than me, for what that is worth.

As Jeff said, Camera RAW > Geometry and use the vertical align tool. I also tried doing it manually with Free Transform, but Camera RAW did a better job.

The new(ish) Content Aware Fill (under the Edit menu) did a good job of filling in the corners. The right hand side is exactly as it came from CAF. The left side had some minor tweaking to fix the window.
