The video above details some really fun things one can do by freezing motion varying the exposure between 1/100 to 1/1000 of a second. The camera is of course set to manual, as well as continuous capture to grab several frames in quick succession. Water is being poured into a wine glass that has been mounted at an angle whilst the main light source illuminates from behind a defused background (velum). Adding some food colouring to the water creates that additional level of drama and dimension to the shot.
The next video looks at capturing the splash of a water droplet. Again like the previous setup this is done without the use of flash photography techniques, though they both make-use of a continuous light source.
Another fun experiment to do is to capture bubbles as they float down to earth. To really freeze the motion exposures on the order of 1/250 of a second allow for some interesting shots to be captured.
One further interesting video fairly similar to the second last one in which the task is to capture a splash, instead of capturing a water drop, this time the task is focused on capturing the splash caused by the dropping of a spanner into a tray of water.
Gavin Howie also has a nice video demonstrating how to capture water splashes. Initially he uses a white sheet of paper as a background. Towards the end of the video he looks at the addition of colour to the image, firstly by changing the white balance, in this particular case he uses tungsten. The alternative option is to use a coloured background that results in some really interesting colouration on the waters surface.
If you happen to have an aquarium floating around then you can have a go at dropping a selection of fruit and vegetables in and capturing the motion of the impact and splash.
Its always of course useful to take a look at the user manual of your camera to be familiar with the settings. In the case of the Canon 600D one can download the user manual from the support page on canon.co.uk. You will see on page 88 of the manual that the Canon 600D is capable of shooting about 3.7 shots per second in continuous mode. One can find details about the Tv setting on page 94 allowing for motion to frozen or blurred.
