You've never been to a warm country did you? There are millions of pics with that kind of lighting in real life. Even last summer here in Belgium we had full orange glowy sky.
Every photo has a filter if you look it that way, there are tons of pics that all look the same. Do you think they just put some orange layer over the sky everytime the sun gets lower? You guys need to go outside more man.
thats the first photo with orange sky that comes up on google search when i search for MT panorama. Here is another one, google image is filled with pics like this and yet they call it all filter and act like real life doens't have orange skies.
Also here is a video if you think the pics are all photoshopped to make them orange
Looks pretty orange to me
