Hi, FamilyGuy!
I took the picture about 5 years ago with a Canon 7D and an EF 100mm f/2.8 L lens. I recently revisited the RAW file. I did a basic RAW processing in Luminar 4 and then transferred it into ON1 Photo RAW 2020 where I did a bit of texturing. I sharpened it in Topaz Sharpen AI. I can't be too precise since I tend not to pay attention to my workflow once I'm done with a picture. Looking back at the RAW file, though, the post-processing I did was more in the way of tweaking rather than a major overhaul.
