As Stan notes, apparent water path can be substantially affected by the motion of the "bucket" or other water source. If you can move the water source rapidly compared to the velocity of the ejected water you can achieve complex shapes.
The composite photo below shows a number of attempts to achieve a version of the much tried summer-beach-hair-water-cliche photo. It's been done a million times, but can still be fun :-). (Trying to synchronise 2 people makes it far far harder).
As can be seen in the multiple images, the water source (hair) is not where most of the water is when the photos is taken, the paths can be given complex curves, and the water is relatively stationary in the air when the photo is taken.
How far in how long":
Distance travelled under gravity when starting from rest is given by
distance = 0.5 x a x t x t = 0.5at^2.
Using SI system: a = gravitational acceleration ~= 5 m/s/s, t = time in seconds and distance is in metres.
OR distance = 5 x t^2 metres. So
0.1 s ... 50 mm
0.2 s ... 200 mm
0.5 s ... 1250 mm
1 s ..... 5 metres !!!
This means that if you can take the photo very soon after the water has been deposited, very little motion will occur due to falling.
Speed of fall affects sharpness.
Speed is more forgiving than distance.
Speed = gravitational acceleration x time.
Essentially, speed of fall
~= 5 x time in m/s.
~= 18 x time kph
~= 11 x time in mph
