New User Here: How do you save the optics effect in lightroom and export to jpeg?
After importing a photo into Lightroom Classic, you can right-click on it and “Edit in Optics”. We recommend choosing “Edit a Copy”.
Then you can apply Optics filters.
If you are happy with the results, go to File>Exit and Optics will ask you if you want to save. This will render your Optics session and you can export it as a Jpeg back in Lightroom.
Hope this helps.
