When you prepare your photo for posting on the web there are a couple of things to pay attention to. Resizing a photo will lead to lose of detail so the keyword is “sharpening”. I don’t use scripts for this step because I like having total control: depending on the elements of the photo there can be areas where sharpening may lead to unwanted artifacts (usually area with many small and very small elements like small rocks or leaves in the trees).
My method is simple. First I export the photo at maximum quality and 300 ppi from Lightroom. Then I continue editing in Photoshop and after all the retouching is done I resize the photo (CTRL+ALT+I) at 72 ppi with Resample checked and Bicubic (smooth gradients) used. Then I do a sharpening and add a mask to control where the sharpening is being placed.
