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 specie is Phacus suecicus.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. |
