Photos at the PhotoSIG site and Foto Natura 🌍

It was pointed out to me that there is a free registration at the PhotoSIG site, which does allow you to view the full size images.

The site does not have a search engine at present, but you can use a Google site restricted search as a reasonable alternative.

Certainly worth checking out are the portfolio of Dutch photographer jaaphart/Jaap, and Stevenshof Windmill.

The site also helped me to find Foto Natura which is a Dutch picture agency, with a number of windmill photos. The images are dual captioned in English and Dutch, though you will find more results if you search for windmolen than you do for windmill.
