P: Tilt-Shift & Technical Camera Lens Distortion Correction Tool

I've already posted this in the Lightroom ideas, but it is equally important for ACR to have this feature.

I’d like to request a dedicated distortion correction tool for tilt-shift and technical camera lenses in Adobe Camera Raw.

Many tilt-shift and technical camera lenses do not save shift movements in metadata, making automatic correction difficult. However, some modern lenses, such as the Fujinon GF 30mm TS and 110mm TS, do record shift data, enabling software like Capture One to apply automatic corrections.

Rather than attempting to create lens profiles for every possible shift position, a more practical approach would be to calculate distortion based on the full shift range of the lens when shift metadata is available, while also providing manual correction controls for lenses that do not record shift data.

Proposed Tool Features:

• Automatic distortion correction for lenses that record shift metadata, using the full shift range to determine the correct portion of the image circle for distortion calculations.
• Manual input for X and Y shift values for lenses without metadata support.
• Sliders for barrel, pincushion, and complex (mustache) distortion to fine-tune corrections.
• An adjustable field to specify the radius (in mm) where distortion correction begins, as different lenses exhibit distortion at varying distances from the center.
• A second adjustable field to specify the full image circle radius, providing accurate placement of the shifted image within a larger virtual canvas that encompasses the full range of shift movements. This would allow users to properly align the image before applying distortion corrections.

Why This is Needed:
Currently, correcting distortion for shifted images requires tedious manual adjustments. For example, with the Nikkor 19mm PC-E, users must manually place the image within a larger canvas and adjust distortion—an inefficient and imprecise workaround.

Given that other software already provides automatic corrections for modern lenses and supports manual distortion adjustments for older tilt-shift and technical camera lenses, Adobe should consider adding this capability to ACR.

This tool would be a valuable improvement for architectural, commercial, and fine art photographers who rely on these lenses.

Thank you for your consideration!
