The zoom doesn’t work well when cropping

Subject: Bug Report & Feature Requests: ACR Crop Auto-Fit Behavior Regression & iPhone 17 Pro Panorama Exposure Blending Issues

Feedback Summary & Key Requests

• Crop Tool Behavior Regression: Post-v18.3.2 releases no longer auto-fit/re-center the canvas after cropping. Need a toggle setting or bug fix to restore the classic auto-fit behavior.

• Panorama Exposure Blending Issue: Panorama stitching for individual shots taken on iPhone 17 Pro produces uneven, erratic exposure gradients (extreme highlight/shadow patches).

• Provided Environment: Windows 10 / AMD Ryzen 9 7900X3D / RTX 4070 Ti / 64GB RAM.

Detailed Feedback Content

1. Regression in Crop Tool Behavior (Post-v18.3.2)

• Up to Adobe Camera Raw v18.3.2, cropping an image would automatically adjust and fit the newly cropped frame to the view screen (Auto-Fit Canvas).

• In versions newer than v18.3.2, after applying or adjusting a crop, the canvas display remains frozen at its current zoom level/position instead of auto-adjusting to fit the screen.

• Question/Request: Is this an intentional UI change or an unacknowledged bug?

  • If this was an intentional change, please provide a user preference setting (e.g., "Auto-fit canvas after crop") to restore the legacy behavior.

  • If this is a bug, please release a fix promptly. This regression is inconvenient enough that it forces a rollback to v18.3.2 after every attempt to update.

2. Severe Panorama Exposure Blending Artifacts (iPhone 17 Pro Captures)

• When stitching a series of individual frame shots captured with an iPhone 17 Pro into a panorama, the exposure integration fails severely.

• Instead of smooth exposure transitions across frames, the resulting panorama contains extremely inconsistent exposure levels—producing harsh patches where one section is overly bright while an adjacent section is overly dark.

• The exposure distribution becomes so erratic that the stitched panorama becomes unusable without extensive manual correction.

• Request: Please improve the automatic exposure matching and blending algorithm during panorama merge, ensuring uniform exposure normalization across adjacent frames.
