Here's my first stiched pano in about 10 years. This image is made from about a dozen exposures. The full size file is 6271 x 3024 pixels (10"x20" at 300 dpi) and 55 mb. I needed more exposures not only to get the increased size of the image, but to deal with the extreme difference in lighting outside the cave, and in the mouth, back to my subject. This cave is in the Lost Valley camping/hiking area of the Buffalo River in Arkansas. Lost Valley is a beautiful area with a lot of very photogenic and inspiring natural features on a fairly short, and very easy to hike trail. The guy in the pic is my photog buddy, Edward. I used a Canon 20D on a tripod.
