1.7 More differences between waves and pseudo-waves.
1.8 Commonplace water figures, and miscellanea.
1.9 Relations with other phenomena.
Ambient conditions.
.1 In order to be seen and recorded in a film, the water figures must be unmodified by adverse conditions.
The wind.
.2 Such as the wind, whose speed should be under 0.5 m/s.
Water figures broken by a wind of 2 m/s.
The boat traffic.
.3 Usually, the waves produced by a boat disrupt somehow these shapes. However, not always.

Lusenzo 2006-11-06 u1342; passage of the Moon above the opposite meridian u1204; moon declination : north 24°12; spatiole B u1256; phase velocity of the moon deltins 359,043; variation <+0,607 (607 /600000 of degree /hr). With regard to the water level reference: cm. +20.
Light.
.4 Also the quantity, the type, the direction of light, and the contrasts it creates as well, play important functions, in rendering the water figures more or less visible.
.5 Too much light, for instance, diminish the contrasts.
.6 Up to date, no photo has been shot out of the visible spectrum, most likely the promising frontier, in the development of this research.
.7 Above all, with regard to the various water figures, which appear at the same time, on more than one level, each moving independently, from the other ones. A research line just caught sight of.
