Focus Stacking with Pixel Shift: Twisted, Burned, Broken Downed Tree High in Pine Creek Canyon (Sony A7R IV)

This 12-shot focus stack deserves its own page because of the exquisite detail shot in Sony A7R IV pixel shift mode, a rare win, given how severe the problems tend to be with using Sony’s pixel shift outdoors.

This stack also points out the difficulty of stepping the focus of each shot in the stacking series just right, with not a lot to guide the progression—I created a few unfortunate gaps resulting in softness in places. Yet the resulting image still impresses.

Includes images up to camera resolution, plus 243 megapixel version upscaled by Gigapixel AI.
