Yosemite National Park (Reworked)
*** In response to complaints about the blue cast, I have reworked this image in Photoshop to reduce the blueness in the rocks. As a result, the picture now departs from the original caste of the transparency, but is more representative of the Real Thing. I must admit, I think it's an improvement. ***
Two XPan pictures stitched together vertically. Standard 45mm, f4 lens with CWND and polariser filters.
I scanned this after re-jigging my scanner (Flextight Precision II) to output 4 times its normal illumination by installing a different lamp (unauthorised mod). The original was about 1.5 stops underexposed (through an amazing and unprecedented technical oversight by yours truly).
The stitching software was "Panavue", very worthwhile, especially at US$65. Although this was a hend-held capture, stitching software likes lens nodal points to be adhered to as the camera is rotated. Things get about 1000% easier if you can lug a properly calibrated panoramic head, like a Manfrotto 302 or similar, with you (not always practical, I'll admit).
On the other hand, shots with nothing much in the foreground - in this case the foreground was air - will usually succeed, as parallax error is reduced with distance to subject.
The sky here was "real", if polarised. It's a pity I couldn't upload a bigger image: the detail in this shot is infinite. What a lens!
