> "Fake" images are images with intent to deceive
The ones that make the annual rounds up here in New England are those foliage photos with saturation jacked. “Look at how amazing it was!” They’re easy to spot since doing that usually wildly blows out the blues in the photo unless you know enough to selectively pull those back.
Photography is also an art. When painters jack up saturations in their choices of paint colors people don't bat an eyelid. There's no good reason photographers cannot take that liberty as well, and tone mapping choices is in fact a big part of photographers' expressive medium.
If you want reality, go there in person and stop looking at photos. Viewing imagery is a fundamentally different type of experience.
Often I find photos rather dull compared to what I recall. Unless the lighting is perfect it’s easy to end up with a poor image. On the other hand the images used in travel websites are laughably over processed.
