I am in the process of updating my site and improving (I hope!) the appearance and navigation. I am a dedicated follower of CSS and all my pages will be refurbished using the CSS technique. Not every page will be instantly updated. This takes some time.
This site has grown from a few pages to a large collection of information about Leica, BW photographic techniques, optical topics and also historical topics. I intent to provide the visitor with information that is as accurate as possible. In science and engineering it is customary, if not mandatory to check and recheck current knowledge to question its validity in the light of factual experience and logical reasoning.
Today I know more than I did ten years ago. Some of the things I thought were true then, are no longer true and some facts are plainly wrong. I do receive many e-mails of persons who point out typographal errors and factual errors. I am thankful for this information. As a result, I am updating my text and sometimes do a complete rewrite.
My previous email address was so loaded with virusses and spam that I had to find another one and change the provider. My new email address is a kind of alias. I can recieve emails in this box, but this is a public one and I will only sparingly reveal my real email address.
