The drape of the ice surface suggest that glaciation had to be very intense and sudden: one has the impression that the movement of water and the ripples in contact with obstacles have been frozen in a few seconds.
The water of this stream is of very high purity and of
beautiful clarity: the photograph is clear to the bottom of the river and we can be distinguish autommne sheets resting on the river bed.
The freezing of water seems to have changed the index of refraction: unlike the usual, light rays are only slightly deflected at the interface between air and water. The branches remain almost straight instead of being "broken" as this is in normal times.
Photography
The photograph was taken in mid December, for an afternoon very cold. The sun was not very intense. The camera has been set on aperture priority. With a sensitivity equivalent to ISO-200, I chose an aperture of F / 5 (low luminosity). The speed was 1 / 50.
Variant
In the workshop, I posted the same image, a retired black and white. Thank you for your opinion. |
