底片欄如何放大

Hey, @wise_listener7777. Welcome to the Lightroom Community. I'll need more info to help you figure this out. 

Please share a video & screenshots of the workflow, as well as system information from Lightroom Help > System Info> Copy and paste into a text document. Then, upload and attach it here, along with specifics about what you need help with.

At this point, the information I have is too limited to be of help to you.

Thanks!
