Zoom into the valley on this one and you can pick out people on the golf course. Not as smudges, but as individual figures, going about an ordinary evening, with no idea they are in a photograph. That is the most useful thing I can tell you about what 100+ megapixels actually means.

The file is six high-resolution frames stitched together, shot on a Sony A-99ii with a 70–400mm lens at around 120mm. The frames were taken as vertical panels rather than horizontal ones, and that is the whole reason for the focal length: turned on its side, each frame fills top to bottom with valley floor, mountain and cloud together. Shoot the same sweep horizontally and you either lose the sky or lose the ground. Six verticals side by side give you the full height of the scene and the full width of the valley at once.

What that buys is a print that changes as you approach it. From across a room it reads as a clean, open landscape: blue sky, white cumulus lit gold along the edges, warm light on the rock, a band of desert green below. From three feet away it becomes a different photograph: individual houses on the lower slopes, vehicles, the texture of the fairways, the people.

These files can be printed large enough to fill a wall, and custom ordered up to 6′ × 20′ or beyond. At that size the detail is not a technical novelty. It is the whole reason to hang it where people walk past it closely.
