When you’re new to the photography game, it can be easy to be drowned by all the different phrases and terms you hear the professionals use. This shouldn’t discourage you, though, it’s pretty to easy to grasp what the basic stuff means pretty quickly, Creative Market have helped by making this easy-to-digest graphic that explains what some common DSLR terms mean.

Sound & Water Experiments ! Awesome !!!

Cool Sound and Water Experiment!

This is really simple but has such an awesome effect. Fill a bucket full of water and place it about 5 feet off the ground. Place a subwoofer about 1 foot lower than the bucket. Run a plastic tube from the top bucket down in front of the subwoofer. Tape the tube to the front of the speaker. Then aim the end of the tube to an empty bucket on the floor. Get the water flowing from the top bucket. Now just generate a 24 hz sine wave and set your camera to 24 fps and watch the magic happen. Basically your cameras frame rate is synced up with the rate of the vibrations of the water so it appears to be frozen or still. Now if you play a 23 hz sine wave your frame rate will be off just a little compared to the sine wave causing the water to “move backward” or so as it appears. You can play a 25 hz sine wave and cause the water to move slowly foward.

Really fun experiment. You should definitely give it a try.

Amazing Water & Sound Experiment #2

Ever since I created the first version of this video a year ago I’ve been wanting to try it again with more water and better lighting / footage. This is a really fun project and when you first see the results, chances are your jaw will drop. The main thing to keep in mind for this project is that you need a camera that shoots 24 fps.

The effect that you are seeing can’t be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you’d have to use a strobe light.

For this project you’ll need:

A powered speaker
Water source
Soft rubber hose
Tone generating software
24 fps camera
Tape.

Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose.

Set up your camera and switch it to 24 fps.  The higher the shutter speed the better the results.  But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker.  Set your tone generating software to 24hz and hit play. Turn on the water. Now look through the camera and watch the magic begin.  If you want the water to look like it’s moving backward set the
frequency to 23hz. If you want to look like it’s moving forward in slow motion set it to 25hz.
