Just amazing. There are no words to describe the creativity of this photographer. Each photo is a work of art, conceived, reasoned and then developed. I recommend watching the video (Ted Talk) in which he clearly explains the process of making these photos. Visit his website https://www.erikjo.com/ and his Instagram account https://www.instagram.com/erik.joh to admire his wonderful photos.
His Youtube channel is full of video explaining how he realizes his works. Have a look to the following playlist!
