Export photos to a Photoshop droplet. The droplet can be created to run a sharpening action. Google 'lightroom to photoshop droplet' for examples. Or download this pdf: run a Photoshop action from Lightroom.
Just curious why you prefer to use a less productive intermediate Photoshop step to sharpen instead of sharpening in ACR which would be more productive for 1-3K images?
I noticed that photoshop id doing much better work sharpening then lightroom does.
Would be curious to see some Photoshop sharpened images and some unsharpened originals before sharpening. You should be able to get a good job done in ACR and it would be way more productive to include the sharpening when rendering from the raw files. Photoshop has many options for sharpening, there are so many tricks and different approaches. ACR is no slouch either, however the two are different.
Remember that output is the key, monitor previews are not representative of the final printed results – unless of course print is not a concern and you are handing off images with lesser sharpening than is required for output.
If I had 1-3K of images to process, then I would likely be looking for productivity. That being said, it would surprise me if you were really handing off that many images in a final wedding package.
