Focus Stacking Optimization: that last INF frame 📹
re: videos by Lloyd
re: panorama
Double whammy win: overcome the Focus BKT infinity-frame bug *and* get superior sharpness.
Some cameras like Fujifilm GFX100 fail to reach INF focus. Sony also fails in some cases, at least the outer zones.
- Always shoot an INF frame with such cameras.
- Shoot an INF frame at optimal aperture even for cameras that do it right eg Nikon mirrorless also.
- Using optimal aperture for last frame eg f/5.6 or f/6.4 instead of f/8, f/9, f/11
- Retouching: brush over INF with that one optimal frame.

Diglloyd Making Sharp Images articulates years of best practices and how-to, painstakingly learned over a decade of camera and lens evaluation.
Save yourself those years of trial and error by jump-starting your photographic technical execution when making the image. The best lens or camera is handicapped if the photographer fails to master perfect shot discipline. High-resolution digital cameras are unforgiving of errors, at least if one wants the best possible results.
- Eases into photographic challenges with an introductory section.
- Covers aspects of digital sensor technology that relate to getting the best image quality.
- Technique section discusses every aspect of making a sharp image handheld or on a tripod.
- Depth of field and how to bypass depth of field limitations via focus stacking.
- Optical aberrations: what they are, what they look like, and what to do about them.
- MTF, field curvature, focus shift: insight into the limitations of lab tests and why imaging performance is far more complex than it appears.
- Optical aberrations: what they are, what they look like, and what to do about them.
- How to test a lens for a “bad sample”.
