The West Castleton Fold was the subject of my second ever (non-robotic) GigaPan (http://share.gigapan.org/viewGigapan.php?id=1204). This shot illustrates the axial region of a recumbant syncline in the Poultney Formation of the Giddings Brook Slice of the Taconic Allochthon. This outcrop is a textbook example of axial cleavage-bedding relations in the hinge of a fold. There are some remarkably ptygmatically folded quartz-rich layers interbedded with the slates. Although the light was not optimal when I visited it this summer, I was able to shoot a far more detailed GigaPan using the Epic100 robot. Light was fading as sunset approached, so I've taken this shot into Photoshop in order to try to optimize the image. The original (pre-photoshopping) metadata is included below: Stitcher Notes: GigaPan Stitcher version 0.4.4090 (Windows) Panorama size: 4250 megapixels (88928 x 47795 pixels) [Cropped in Photoshop to 4032 megapixels - 85663 x 47063 pixels] Input images: 840 (35 columns by 24 rows) Field of view: 87.1 degrees wide by 46.8 degrees high (top=42.8, bottom=-4.0) Settings: All default settings Original image properties: Camera make: Canon Camera model: Canon PowerShot SX10 IS Image size: 3648x2736 (10.0 megapixels) Capture time: 2009-06-03 19:07:07 - 2009-06-03 20:01:44 Aperture: f/5.7 Exposure time: 0.025 ISO: 200 Focal length (35mm equiv.): 565.2 mm Digital zoom: off White balance: Fixed Exposure mode: Manual Horizontal overlap: 23.9 to 51.8 percent Vertical overlap: 23.4 to 68.4 percent Computer stats: 3069.98 MB RAM, 2 CPUs Total time 14:38:02 (1:02 per picture) Alignment: 3:45:13, Projection: 45:49, Blending: 10:06:59 |

A wide view of the West Castleton Fold. The West Castleton Fold was also the subject of my second ever (non-robotic) GigaPan (http://share.gigapan.org/viewGigapan.php?id=1204). Lighting was not optimal this time, but I did the best with what I had. Unfortunately, there would not have been time to shoot bracketed HDR images at the same resolution. |
