What Is Macro & Focus Stacking?
The plain-language entry point: what macro actually means, why depth of field collapses at high magnification, and how focus stacking rebuilds it — no prior background assumed.

Practical articles developed from repeated high-magnification capture, failure analysis and workflow refinement. Each note explains an optical or mechanical limitation encountered in real specimen work, why it occurs, and how it is mitigated in practice.
