In the area where I live there are several places where groundwater is welling up. This water is rich in iron and when in contact with air extremely thin films are formed at the surface by (bio-) chemical processes. In these films colour shifting occurs. However this strongly depends on the view direction. Therefore I did not put the camera perpendicular to the water surface, but at an angle for maximal colour. The final image is the result of a focus stack of seven images, combined with Zerene Stacker.
Igor, you’ve got a fine, painterly view here, with fine subtle colors and fascinating textures. Refraction in thin films makes some very colorful images, it’s neat that this is a biochemical, iron based process. The mottled texture with the “islands” of solid material has me thinking that a microscopic view of the island region might be fun, but that would need a very different set of hardware. A great find.
