The pages in this website are mostly notes, which instead of keeping private, I share in the hope that others may find them useful. This website is mostly about digital photography techniques with emphasis on nature and macro photography. Tests and reviews attempt to explain the origin of the differences in performance between pieces of equipment or methods in general, rather that specific ones.
In August 2023 I transferred this website from WordPress to Quarto. Only the URL to the home page remains the same. URLs to individual pages, posts, and illustrations have all changed from those in use before 2023-08-22. Most content from the old website that was still relevant is available in the new website, most of it edited and in some cases merged. I did not transfer the content that I considered no longer useful. The new website has built-in search, and I hope this alleviates the inconvenience caused by the broken URLs.
The old site has been regularly archived by the WaybackMachine since August 2020, and continues being archived.
