Aperture Series with Focus Stack: Boulder Escapee from Rockfall (GFX 50S)

Shot with Fujifilm GFX firmware 2.00, lens firmware 1.00. Brand-new GFX, brand-new lens.

This aperture series from f/2.8 through f/13 shows the separation powers of wider apertures along with the total inadequacy of f/13 to deliver depth of field in a near-far scene like this.

To contrast f/13 depth of field, an 8-frame focus stack at f/10 is included. Worth noting is that not all frames need be stacked; as an aesthetic choice the full depth is stacked, but it might have ended, say, at the rear of the boulder—one need not include all frames in the stack.

Additional comments on focus shift round out this as a very instructive example.
