Question

Auto Sync - Basic Develop sliders not working across multiple selected images

Lightroom Classic 15.3 on Mac. Auto Sync is enabled and working for Profiles, Presets and Denoise across multiple selected images. However Basic Develop sliders (Exposure, White Balance, Contrast etc.) affect only the first/active image. Preferences reset, catalog optimization and restart did not fix it.
Seems like a bug affecting Develop parameter synchronization.

    Unfortunately I can’t help but wanted to say I’m experiencing the same behavior. Some things will auto-sync but most will not. I can auto-sync resetting crops but not applying crops, I’m not seeing any develop adjustments auto-syncing. LrC 15.3

    Hey, @Marina2986136113am. Welcome to the Lightroom Classic Community. I'll help you figure this out.

    In my quick attempts to recreate this, Lightroom behaved as expected. I worked through a collection and enabled Auto-Sync with sequenced images and separate selections.


    Could you reselect the files and ensure that the Auto Sync switch is enabled? If it's not activated, click on it to enable Auto Sync mode. Also, it'll help if you record a video showing the steps to repeat the reported behavior.


    Thanks!

    Hi ​@Sameer K 

    thanks for your reply.

    I recorded a short video demonstrating the issue.

    Auto Sync is enabled and working partially:

    • Presets are applied to all selected images

    However:

    • Basic Develop sliders (Exposure, White Balance, etc.) affect only the active image

    So Auto Sync is clearly active, but Develop parameter changes are not synchronized.

    Thanks!
