Lightroom Export why building Standard Previews?

[shayb68441784]

I notice after exporting a large batch or images, Lightroom is busy "building standard previews". And that slows thing down to some extent. How can I stop this auto preview buiding in standard while exporting? I don't need standard previews and want to move on with my tasks as quickly as possible.  To speed up my workflow I usually only import with "embedded and sidecar" previews. But there are no choices for previews upon exporting.

Do you have Add to This Catalog checked in the Export dialog?

If you do, the exported images will be imported in LrC, and previews will be built for them.

Yes, "add to catalog" is checked, but I don't want or need standard previews built, hence my complaint. If we get preview choices when we import, why not in this case? I would argue that there's much less reason for "standard" previews upon export, as the photos have already been viewed and edited.

Every non-raw image in the library will get standard previews built. It is necessary to be able to display them. For raw images you can select to import using built-in previews since they actually have built-in jpeg previews but that can't be done here when importing jpegs since they don't have built-in previews. So you either make a copy of the actual jpeg into the preview database which doubles the storage requirement or you generate a standard preview.

Also, why import exported images? There is usually no point. If you need these images again sometime in the future, just export from the originals instead.

Ok, that makes sense, thank you. To answer your question "why import exported images?", I will quote from Adobe, "Lightroom Classic on your computer offers a rich set of tools for organizing your photos. Collections, keywords, face recognition, flags, stars, color labels, and a variety of useful search filters give you multiple ways to keep track of all the photos on your local drives.". Lightroom at its core is a great organizational tool. But it can't keep track of images that aren't imported into the catalog.

Yes, you keep track of the originals in LrC using all of those great organizational tools. You don't have to keep track of exports using those tools, as you can always export again if needed by finding the original in LrC and then doing the export. All of my exports go into a Temporary Folder, and are deleted a few minutes/a few days later.
