William Edward Fox, "Walk in the Park"

The image below is a good example of what can happen if someone over-edits a photo, especially one that's excellent to begin with and doesn't require any improvement. An amateur editor has heightened the sharpening and contrast without taking into consideration the way those changes would alter the naturalistic, very detailed and life-like qualities of the original. In fact, the updated version looks more like a drawing than an oil painting. There's also an unnatural, yellowish cast, and a section of the painting has been cropped off at the top.

The photo above is from Uppsala Auktionskammare, Sweden, where the painting sold at auction in 2018. It took some time to track down an reliable image, so it's understandable that people online are using a more accessible, revised version instead. Still, it's preferable to see an image that's more faithful to the genuine painting, and more consistent with the artist's other work.
