Golden glow, large format film photography

I was up in Muskoka (at Cleavelands House) with my soon-to-be inlaws and got up with my brother-in-law one morning at 4:45am to do some sunrise photography. Ugh, is that ever hard! Still, the results were worth it and I love how Velvia renders soft, golden morning light.
