Question s on 32-bit processing workflow

I have two very specific quesitons on using Lr and PS to process 32-bit images. 

1. As I understood it, when I move three bracketed images to PS to do a 32-bit HDR merge, when I save an ?HDR merged photo,, PS is suppoosec to retiurn thart final image to Lr where it originated. In my case, I keep having to save it as a TIFF file on ny desktop and then drag that back into Lr. What am I missing?

2. I mostly want to return the fikle to Lr for storage, but if I happen to make further changes to the photo,. is LR resetting the image in 16-bit or keeping it as a 32-bit?

 

Thank you for any hlep.

Hey, @Paul3452268254wo. Welcome to the Lightroom Community. I'll help you figure this out. 

 

Is there a workflow requirement for you to use Photoshop to merge HDR images? Lightroom and Lightroom Classic can handle HDR, Panorama, and even HDR Panorama. Please head here to get started: https://helpx.adobe.com/lightroom-cc/using/hdr-panorama.html

 

The Edit in workflow won't send back the new HDR image created in Photoshop as it is a new file. You'll have to keep importing the TIFF files. Lightroom can manage and edit 8-bit, 16-bit, and 32-bit TIFF images.
