What it is
Worik posted a link to a DPReview article about a photographer whose site is charlesbrooks.info. The thread has about 50 comments. They mostly react to the images and discuss the optics, instrument making and acoustics.
What it says
- Wowfunhappy quotes the article: focus stacking reduces background blur, so scenes look large.
- Susam says merging shots at different focus distances removes depth cues.
- Commenter charlesbrooks, a name matching the linked site, says mirrors give faint double images.
- Commenter hn_throwaway_99 explains that wooden pyramids inside old basses and violins are repair cleats.
- Commenter CPLX says symmetrical, parallel surfaces cause standing waves, so varied shapes give richer timbre.
- Commenter susam suggests a game: hide the captions and guess each instrument from its photo.
What evidence it gives
Commenters give explanations from experience and general knowledge. A few add links, such as a guide to making and fitting cleats. One quotes the article directly. Nothing in the thread is tested or sourced beyond that.
Interests and limits
Commenters are anonymous, and their explanations are unchecked. The linked DPReview article and photos were not viewed. Only the thread text was read. One commenter complains about popups on the article site.
Connections
These links are this wiki's own reading, not claims the sources make.
- Autostereogram. Focus stacking inside an instrument removes depth cues, so small spaces look huge. An autostereogram goes the other way, hiding depth in a flat pattern. Together they suggest depth is inference, not sight. Both edit what the eye uses to judge distance.
