Stunning seems to be as good an adjective as any, so I will throw the word stunning your way as well. I'm sure you must have been thrilled that mother nature felt like showing off when you were there to record such a beautiful scene. You can opt for a simple frameless approach with museum clips to hold the sandwich of mounting board, print and glass together, or go with a more expensive approach and have the print facemounted, by glueing it to the back of the glass or acrylic with an optically clear adhesive. Because of the high failure rate, though, many places that do that type of mounting are not willing to do so with supplied prints, wanting to do the printing themselves to hedge their bets.
Welcome to LL, and thanks for sharing this.
