>The sun in the background was sharpened via a stacked image but the image is 100% real and authentically captured in camera (see the video in the OP reply for real time view). Not a composite!
He just kept shooting the sun after the jumper cleared, and stacked up those shots. I think saying it's a 'composite' devalues the image and just makes it seem like he cut out the jumper and pasted on to the sun.
