UV-induced visible fluorescence (UVIVF) is a very interesting phenomenon, which uses ultraviolet light to induce subjects to fluoresce in the visible light spectrum. UVIVF imaging requires a dark room so that the only light visible is that which comes from the fluorescence of the subject; the UV light also needs to be blocked by the use of an UV/IR cut filter on the camera lens.

My wife makes the nicest lasagne I have ever tasted. Every time she makes it, we would eat more than what we should. But we never get sick or tired of eating it. Particularly in winter, the cheese and meat will help to keep us going in the cold weather. Continue reading Food photography: lasagne

This is a fairly thin helicoid focuser (unbranded) which I bought on eBay. It is probably amongst the thinnest helicoid focusers available, which could allow for mounting of filters between the lens and helicoid. Continue reading Helicoid focuser – thin M42 to Micro 4/3rds

Here I have the Nikon G to Micro 4/3rds helicoid; I also own the Nikon G to NEX helicoid. These allow for direct mounting of Nikon lenses to Micro 4/3rds and NEX; other helicoids require at least another adapter in order to mount Nikon lenses to a mirror less camera. I gather Fotodiox also make a Nikon to mirror less camera helicoid adapter, and I have made enquiries regarding their Nikon-Micro 4/rds helicoid adapter.
