Walking trail along the River Torrens from the beach to the city of Adelaide, where it crosses Apex Park.
Title says it all , a right tangle of wires going off in all directions - forget wi-fi , this is landline communication in the air !!
Oh , don't worry about the fixture bottom left as this is only a ladder bracket on a roof rack on top of a van - I just kept it in as it gave a kind of balance to the shot to my mind !!
Many people are astonished that it is possible to capture the Milky Way from a fast moving airplane without star trails. What they are not aware of, is the fact that the speed of the aircraft (linear motion) is irrelevant, due to the huge distance of the stars. Not even the much faster velocity of earth moving through space has an impact.
It is earth rotation (angular motion) that causes star trails. When flying westward, star trailing is even reduced by roughly 50%, as it has the same effect as tracking the stars at half speed.
On the other hand, most people are well aware that camera shake destroys any astrophotography. Unfortunately my 300'000 kg flying camera mount is very prone to turbulence and aerodynamic oscillations. It therefore does not happen very often that I am able to capture a sequence that allows stacking. Luckily there is an exception from time to time: Thanks to a really smooth ride during this flight over Norh Africa, I was able to stack 10 exposures. The lights on ground show the fast linear motion that leaves the stars totally unimpressed.

Les ombres linéaires du soir donnent des images assez dramatiques, une fois retravaillées.
Comme quoi, pas besoin d'aller loin pour s'amuser, un jour de fatigue...

Another photo of Guillemins railway station in Liège, Belgium. As with many of architect Santiago Calatrava's buildings, I think it is impossible to resist the visual hypnotic spell the design puts on you. With every step you take, the perspective changes and the lines intersect differently. It feels as if you are surrounded by some (friendly) alien being that is alive and follows your every move. This effect even becomes stronger when the sun comes through and even a huge grid of shadows joins the party.
