Episode 24 about infrared image processing with dartkatble is again about ColorKey processing of a 720 nm Infrared Image. The photo from the park of the Hülshoff castle near Münster was sent in by Ulrich Heczko.
I am looking forward to your photos that I can edit in the future. Just write me if you have a picture for editing!
You can find more photos of Ulrich Heczko in the Oly Forum or on youtube:
