Synch Issue

I confirm that my all images are exactly the same exif. ISO, shutter speed, f value, etc. and there is no scenery change because of milkyway timelapse shot.

First image has color corrections, crop and some masks (total four masks which are sky, linear, brush).

When I tried first time that I saw some color changes than ı remove all 492 images from lightroom than I called back raw one without any develope than ı synched all of them according to developed one

Hi ​@burcinbahsi,

Thanks for reaching out. First, I’d like to confirm which Lightroom application you’re using.

• If you’re using Lightroom Classic, the app icon will show LrC.

• If you’re using the cloud-based Lightroom, the app icon will show Lr.
   

Could you please go to Help > System Info, click Copy, and paste the contents here? That will tell us exactly which application and version you’re using.
 

Also, just to make sure I understand your workflow correctly, are you copying/syncing the settings from one edited image to the other 492 images? If so, could you confirm whether all of those images have the same pixel resolution, aspect ratio, and orientation? If the images don’t have identical dimensions, framing, or rotation, adjustments such as crop and masks (linear gradients) may not align correctly after pasting/ syncing the settings.
 

I'm looking forward to hearing back from you.
 

Best,
Anshul Saini
