Here are some very interesting water sculptures produced using high-speed photography*:

Pretty amazing... But how did he make the water go like that? Does anyone know how he could have made this one:

Beautiful...
The photo you are asking about, I think it's done using some, let's say wind generator machine, or just a cooling fan, I am not sure, but I think that it's done this way.

On the last two photos are schematic figures of how they did it, but I bet that there is more than that.

To be scientific here these are liquid sculptures and not exactly water water would be unattractive as there would be no colour

Well, to be equally scientific, the colour of water is blue. It is also possible to light water in such a way as to produce other colours on film. Finally, of course, one can use post-processing to utilise various colour pallets.

All present and correct. Smile

i find 6 colors: red, green, blue, their antis suffice* when blended and spun correctly. Very Happy

If liquid water had to be totally pure in order to be called 'water,' we wouldn't be able to use that term for any liquid on Earth.

much of the blue color you see comes from the water's depths
Well you are correct when it comes to water bodies and the blue color strengthens when the thicknessof the coloumn increases
but here in the photograph there hardly droplets o f water
Actually I think
water is not really bright blue, but part of the sun’s light is blue. Since short blue wavelengths from the sun eventually hits into relatively large oxygen atoms in the water, the blue light tends to bounce off and scatter in all directions and reflected to our eyes.
Now again we have to know under what light conditions the photographs were taken
Did they really put in colour palate into the photos

That's crazy, that must take a lot of patience to pull off well.

Actually if there were no red light ie 650 nm in the lighting condition of the photograph the water would not be blue
There are two things to consider in this photos
1. There was red light : then the water would be blue due to high overtone and excited vibrations causing intrinsic blue colour as against only reflected blue colour
2. The photos were manipulated to add colours

It is just the state of matter that I am talking about not the purity

Actually there is a mention of dark room in the site by the photographer
I would be interesting to know
the spectrum of the source light for the photos and equally if colours were not added ie the true colour of the photos

Pure water is almost totally transparent to low frequency radiation say lambda= 30 cm or 1 GHz
since there was a loud speaker here we know that wavelength of
assuming that the loud speaker would be emitting something between 1,000-5,000 Hz
I think that complicates the issue
anyway I would like a conversation with the photographer he/she has done a great job!
