The pages in this website has two different sections, pages dedicated to advertise services I am ready to provide commercially and a blog titled ‘Photo Rumblings and Whispers’ containing mostly notes about techniques, equipment and software that I use or have used for photography. I share these in the hope that others may find them useful when taking photographs or as information on services I can provide. This website is mostly about digital photography techniques for nature and macro photography, with emphasis on documentary photography as used in scientific research and in technology. Tests and reviews attempt to explain the origin of the differences in performance between pieces of equipment or methods in general, rather than assessing specific pieces of equipment.
After formally retiring from my Senior Lecturer position at the University of Helsinki in September 2024. I have registered as entrepreneur obtaining a Finnish Business ID and VAT registration to be able to provide consulting, training and other services against payment by invoice. I have a long experience of working in collaboration with experts outside my main field of research and in teaching. My expertise includes 1) the statistical design of field and other experiments related to crops, plant ecology and plant physiology; 2) data analysis and data visualization in R; 3) development, publication and maintenance of R packages; 4) typesetting reports, scientific journals and books with \(\LaTeX\) and/or Quarto; 5) digital imaging in the ultraviolet, visible and near-infrared radiation, from macro range to landscape; thermography; time-lapse; focus-stacking; imaging of autofluorescence from plants and objects; 6) spectral and broad-band measurements of ultraviolet, visible and near-infrared radiation.
I can provide various services with my own equipment and others with customers’ equipment. Separate pages describe data analysis and visualization services, plants and agriculture research services and technical and scientific photography services

I keep a website focusing on data analysis and visualization and plant fotobiology research under another URL: https;//www.r4photobiology.info.
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.
