Almost every photo ever taken benefits from some (or a lot of) post-processing. I have been a fan of the Topaz Labs products for years now, in particular Denoise AI and Sharpen AI. Recently, Topaz Labs have combined these, plus Gigapixel AI, into a new product called Photo AI. It can be used as a stand-alone product, or as a plug-in, eg for Lightroom or Photoshop. I mainly use it as a plug-in for Photoshop.
Once you open a photo in Photo AI, the software analyses the noise level and the sharpness and then automatically edits the photo. If you use it as a stand-alone product, it also gives you the option to re-size the photo, up to 6 times larger.
Topaz products have a 30-day free trial, so you can use them for a while and decide if it is for you.
