I have read an article with on Luminous Landscape or from this site to another site on using a prime lens set on infinity where a ratio of the lens size to aperture puts everything in the ratio in mm in focus. This was first written about last century.
Any clues where this article is or an original article of the site would be greatly appreciated. Cheers Aussiejim
