I've recently discovered Brandt, and have become a huge fan of his works. I have been thinking about his methods for some time, although I haven't tried any until today (because of this thread, which explains the model used). I literally just took this picture to show that the image being discussed (as well as many others of his) is all about wide angle lenses and huge depth of field that is inherent in UWA lenses.
This was shot
handheld on my Canon 50D, with a Rokinon 8mm fisheye. ISO 100, f/22, 1/6th second. Focus was set at roughly 1.2 feet. The swing in the background is about 26 feet away, and the elephant (which would have been my daughter, but she's at a friend's house) was about 6" away from the front of the lens.
The first is an uncropped RAW to jpeg conversion, and the second is cropped to eliminate the 'fisheye effect' that can be seen at the bottom. Notice how the roofline has minimal fisheye effect.
Enjoy....
