So, I look at these photographs full screen and download and enlarge, and then enlarge again, and then again. They are sharp from foreground to far distance. Are they focus stacked or hyperfocal or some other kind of digital magic? Please tell me your secret, OH Landscape Master.
There are no secrets involved, Chief. At least, none that anybody couldn't similarly --and routinely-- put to use. The first image is technically a pano, comprised of six separate vertically shot images. Using multiple images in this way almost automatically produces a result that
appears sharper than a single image would have since a
lot more information will have gone into the final output. In terms of depth of field sharpness, like most folks, I lament the fact that most 'modern' lenses no longer have dof markings which would have made things a lot easier, so I followed the basic 'rule' of focusing on something roughly 1/3 of the way into the scene, and know from experience pretty much what'll be acceptably in focus given the particular lens and the aperture chosen.
While its true I do (or try to do) a lot of focus stacking in the field, given the conditions (heavy wind/rain) at the time, there was no possible way to have done so with either of these images. While both are pretty sharp from the get-go, there are ways of
tromp d'oeil-ing a viewer's perception into
thinking something is sharper than it may actually be, and straight-up 'sharpening,' either in camera or during processing, is often not the best way to do it. Color --or tonal-- values, placed side by side, produce the effect best, but when doing so isn't feasible, then edge structure is the next best option. This is basic color theory/visual perception put into practice.
Photographers would do well to study painting method, cognitive psychology, and basic aesthetics a little more than they do lens test charts.
