Description

This panorama was taken from ~100 yards north of the unmarked view point on Hwy 410, ~1/2 mile past the (right-hand) turnoff for Sunset.
In the valley floor is the White River. It was taken as the morning light stabilized, starting at ~9am, and ending at ~925am.
HIgh air clarity is due to unusually dry trough of air that passed through overnight, after a good rainstorm the day before,
and with warm summer temps meaning very few homes were burning fires overnight.

Technical details:

* Gigapan Epic Pro head, set to 2.5s delay (after move, before shutter) to allow vibrations to die down to almost zero
* Camera is a Sony Alpha 900 with Sony G-series 70-400mm f4-5.6 (aka "the monster").
* Exposure is 1/125s, f16, WB set at 5500.
* Each tile image is 24.4 Megapixels, with about 12.3 EV dynamic range (cf. DXo Mark)
* 13 rows of 26 images = 338 images
* Stitcher reports 78204 x 29860 pixels (Mercator projection)
* Tile image post-processing include (most) dust spot removal from the sky, +clarity, sharpening, +saturation, rotate yellows toward green a bit.
* Yellow-reddish hues on the mountain are increased by dwindling "golden light"
