It was shoot at Tatra National Park, which is actually two years ago with my Canon 5D mark IV. At that time, after I did the post processing of this photo, I felt like it's not sharp, the contrast couldn't make the rocks pop out and the details of the trees just wasn't as much as it should be. It's quite disappointing to me and I thought the problem was caused by gears. However, tow years later I did the retouch again on the same photograph, but with different perspective and few a bit better methods, I think now it looks as fascinating as how I imagined in my mind.
I wouldn’t say it's always necessary to do or upgrade the skills of your post processing. However, fully using the technology definitely changes one regular photo to another level. Especially how flexible digital raw file is.
