I import my image into Lightroom CC and share it with a client. The shared image (JPG) has a lower resolution when the client tries to download the file from the shared link. I've tried this and can confirm that the file does have lower resolution when downloading from the shared link.
When I go to the Lightroom Web App and log into my account, I can downloads full resolution image from there.
I would like to be able to share full resolution images with clients and for them to be able to download the same full resolution images.
I understand if the web preview doesn't show full resolution.
As far as I know you can not choose the resolution of your shared images in Lightroom CC. You can do it when Exporting to your HD or an External storage but that doesn't apply to sharing unfortunately. And the documentation does not say anything about this as an option either: https://helpx.adobe.com/lightroom-cc/using/save-share-photos.html.
But the thing is that if you uploaded the photos using Lightroom CC and not Lightroom Classic (with Smart Previews enabled), it should share and allow the original resolution file download. And anyone who access your shared photos will be able to download the JPEG version, not the RAW one. If you upload RAW files Adobe's servers will create JPEGs from them when sharing.
"Lightroom CC... it should share and allow the original resolution file download."
That's the exact problem I'm encountering. Put a file in Lightroom CC, create a shared link, share it with a client, and the file they download is several MB's smaller. Gradients look horrible, colors shifted slightly, and it's not the intended image I meant for them to have. What could I be doing that's different?
