Focus Stacking
Focus stacking combines sharp areas from photographs of the same piece taken at different focus distances. In macro jewelry photography, it can extend usable focus coverage when one exposure cannot show the required depth. Inspect the merged result against the captured frames.
Why focus stacking exists
At close magnification, the nearest prong and rear band can occupy different focus planes. Decide which features the image needs to show clearly. Camera alignment, aperture and distance affect the result; stopping down can also soften fine detail through diffraction. If one suitable exposure lacks the required coverage, capture a sequence with overlapping sharp regions and combine it in a focus-stacking editor.
How focus stacking works in practice
Stabilize the camera and product, keep the exposure and lighting controlled, and capture enough overlapping focus planes for the detail that must be shown. The number of frames, focus increments, equipment, processing method, and time vary by piece and required output. Stacking software blends selected sharp areas, but it can produce halos, doubled edges, reflection changes, or alignment errors. Compare the composite with the individual frames and physical piece rather than assuming every detail is sharp or accurate.
Where AI fits in
A generative edit of one photograph is not the same as combining a real focus stack. It may change the appearance of detail but cannot establish features that were out of focus or hidden in the source. If the required focus coverage is missing, capture and inspect a real stack or take a clearer source photograph. Review the composite and any later retouching against the individual frames and the physical piece.
