Alan has two sites full of remarkable images.
The Photography of Alan Findlay. A cross screen filter, also known as a star filter, creates a star pattern, in which lines radiate outward from bright objects. The star pattern is generated by a very fine diffraction grating embedded in the filter, or sometimes by the use of prisms in the filter. The number of stars varies by the construction of the filter, as does the number of points each star has.
Cross Screens add a dramatic four, six or eight-pointed flare to light sources giving a soft-focus effect. ldeal for photographing highly reflective surfaces such as water, glass or metal. Bright night city-scenes, festive lighting and sunlight on water are particually well suited for these filter
