well I think this ability would put you squarely in the "serious" photography camp. 🙂Also late to the party...and first reaction...seriously?
Many photos are so manipulated in Photoshop/Lightroom - including exposure adjustments utilizing a specific camera's dynamic range, as well as other adjustments, that EFIX borders on meaningless.
Consider the 3 below which was more an exercise salvaging a bad day. For the record EFIX was ISO 400, f4, 1/1250 sec on Sony A7rIII with 16-35 @35mm (my favorite walkaround lens).
Location was Harper Ferry...on a rainy, overcast day. One photo was "almost as taken" with minimal Lightroom adjustment documenting the conditions. Another was exporting to Photoshop with Lightroom adjustments, removing people, a sign, replacing sky which with the wet streets and muted shadows can't be bright and sunny, plus fine tuning tonality/exposure, etc. Finally, noticed forgot to remove the traffic sign so re-loaded the previously saved Photoshop (avoided having to re-edit out the people and other sign) and tried a different sky in the process. So much for the EFIX...but the manipulation did save a challenging day.

The bigger question is do you feel because you have this skillset that you should participate in a dedicated thread with people of similar ability?
