Summary[edit] Description: English: Images have been made by Nikon Eclipse E 600 light microscope using an original magnification of 400x - 600x range, at South-Transdanubian Emvironment Protection Inspectorate, Laboratory for Environment Protection (Hungary). Photos of algae have been taken from samples of natural surface waters of South-Transdanubian region; the majority originated from river Dráva and lake Baláta. Images have been made by phase contrast setting, whereas a blue color filter has been used instead of a green one recommended by the literature. The reason of the change is that although the green filter gives a sharp image, it reflects the shades of gray color only. When using a blue color filter, the sharpness of the image is barely reduced, but the colors of the object are retained. Scientific names of algal speciei are found in the header of the images. Magyar: A fotók a Dél-dunántúli Környezetvédelmi Felügyelőség laboratóriumában készültek, Nikon Eclipse E 600 mikroszkóppal, 400x-600x nagyítással. Az algafotók a Dél-dunántúl (a régió) természetes vizeinek mintáiból vannak, többségben a Dráva folyó és a Baláta-tó vízéből. A képek fáziskontraszt beállítással készültek, de az irodalmi zöld színszűrő helyett kék szűrőt használtam. Zöld szűrővel a kép éles, de csak a szürke szín árnyalatait adja vissza. Kék szűrővel a kép élessége alig csökken, de a tárgy színei megmaradnak. Az algafajok neve a képek fejlécében található. Date: 20 September 2004. Source: Own work. Author: Dr. Imre Oldal.

Häder's cyanograph experiment A photographic negative is projected onto a Petri dish containing a culture of photophobic filamentous cyanobacteria (Phormidium uncinatum). The trichomes cover the lighter areas of the projection while uncovering the darker areas producing a photographic positive. Petri dish is 10 cm wide.
