I spent 2 days at Iguaccu Falls and was somewhat disappointed in the sky. I didn’t even see the sun at all. The sky was overcast and looked like a milk jug. There was absolutely no contrast at all. The whole purpose of my trek there was to photograph it! Well, just as I was leaving the park, I happened to glance over my shoulder and just stopped. My jaw dropped and I shook my head in disgust. This sky, in a matter of about 15 minutes just appeared out of no where! Oh well.
Another cool note is that this was captured with a hand held G9 canon that a friend let me borrow to test out. I did virtually no touch up on this except for minimal camera raw adjustments to the JPEG! Its a great little camera.
