It is a double exposure picture, so NO PHOTOSHOP!!!
It is almost the way it came out of the camera. It was not an easy picture to take. I did it during one of my hikes. I liked it there so much that the mountains give you a certain state of the mind and make you feel closer to the Unknown.
It was shot with the Canon EF 17-40mm f/4L USM wide-angle lens. Camera: Canon EOS 7D Mark II It is an HDR picture. I don't use Photoshop, I am colorblind, I use the Lightroom and work with RAW files.
