This is photo taken on Chatham South Beach. It's an infrared photo but it's processed in Photoshop with what is called "false colour". A sensor that has had the IR filter removed and a visible light blocking filter placed over it no longer "sees" normal colours that we see, however the red, green and blue pixels on the sensor do pick up the IR at slightly different intensities due to the colour filter array that covers them, so this comes through as a false colour balance. This information can be manipulated to give false (and deliberately unreal) blue colouring to the sky while foliage takes on a pinkish tinge. I liked the look of this one in false colour in particular.
