    Hi, Thank you for your comments. The picture is made up of 270 frames. Each frame was taken with three brackets - fixed aperture of F8, ISO200 and a bracketed shutter speed. I'm still experimenting with the whole process but.......... My understanding is one should used both a fixed aperture and a fixed focus so that each frame can be physically stitched together, otherwise detail will not match, either because of focus or depth-of-field changes. Because you have such a different exposure across the image with bright sky at the top and dark shadows at the bottom you find that the slowest shutter speed varies enormously across the image. The whole process of taking 3 x 270 frames took nearly 90 minutes. Obviously exposure changes depending on the main element in the frame so you can get a different exposure if one frame in mainly sky and the adjoining frame is mainly structure. Ideally one would prefer to have taken 5 or 7 brackets to try and even out some of the differences but the time taken would have meant the sun would have moved around from behind the left hand tree! If you look closely there is a variation on sun strength and shadow angle between the left hand side and the right hand side of the image. This also contributes to the slightly surreal look of the final image, something which increases the impression of HDR. Essentially, I am finding that out-door work is a compromise between capturing as much detail as possible without too many of the other variables changing during the shooting period.... On top of this, I am still finding that the Canon G9 is not as consistent as you would wish with some frames not in focus compared to their adjoining frames. It may be something to do with the internal camera processing of the image (noise reduction etc.) but I haven't been able to pin it down yet. I would also like to be able to set the GigaPan to pause for a second or two after moving the camera but before taking the shot so that the camera can "settle down" before taking a shot. This would also probably help. The HDR look of the image is partially caused by the variation across the shot images and partially by the way PTGui has blended the images - another variable I haven't really had time to test !

    Your gigapan has the look of HDR about it. Did you create a high dynamic range image or was the camera set on auto exposure? Great colours and shapes.
