Lightroom/Camera Raw: Please implement a "de-skew" mode for e-shutters

Electronic shutters cause skew when you are moving, also referred to as rolling shutter or a "jello" effect in videos. The read-out of e-shutters is often slow like 1/50s even though the shutter exposure is faster like 1/1000s.

This causes visible skewing of the image, which currently can't be corrected in Lightroom.

In the example below, the vehicle was travelling at ~30mph, and the use of electronic shutter caused skew on the building.

Please can you add the ability to de-skew an image.



While the current Transforms in LR Classic are great, surprisingly there is no way to easily de-skew.

This can be 'sort-of' achieved using 'Guided' but it's fiddly and the results aren't entirely predictable. Easier to drop out into Photoshop (or Elements) to correct the geometry. Agree! De-skew (both horizontal and vertical) would be handy.

Guided Upright seems to work well on the image posted above.  (I loaded it into ACR Filter and drew two vertical lines (on opposite sides of the house), and a horizontal line across the base of the house.

Could you post examples where Guided Upright doesn't work well for this application?
