- parts and tools for making a stroboscope:
- - power supply 9 V, 200 mA;
- - soldering iron, solder, flux and neutral;
- - yellow or orange marker office;
- - flat vessel;
- - Drill;
- - tube;
- - glue.
Normal flash to photograph the incident drops unusable.This is due to the fact that each time the only one it emits a pulse of light, and it is synchronized with the moment the shutter of the camera, not with the moment of falling drops .Requires source periodically generates droplets falling , and a special device - a stroboscope.
There are a significant number of designs of such devices, and to visually stop falling drops will fit almost any of them.The main thing that the pulse duration was considerably shorter than thepauses between them, otherwise drops will look blurry - but the requirements are met almost all the strobe lights.However, the best results will, of course, a strobe, which is specifically designed for observation and photography falling drops.
description of one of these strobe given link located at the end of the article.This is a very simple device.A skilled handyman collect it for only twenty minutes.
For the drops, drill a hole in the side wall of the vessel near the flat bottom of it.Connect the short tube to it, and then paste it.When the glue is dry, fill the vessel with water and ensure that the water poured out of the tube is not a continuous stream and drops.
Turn off the lights and turn on the strobe.Rotate frequency, achieve a visual stop drops (total or partial, in which it seems that drops slowly move down or up).Now you can take on a camera or camcorder.Filming will have no flash.
interesting effect of glowing drops out, if dipped in a vessel filler from yellow or orange marker office, and LED strobe put in blue.
Experiment directing drops on different surfaces.Particularly interesting effects occur, as mentioned above, when the drop enters the vessel with water.This produces spikes, shaped like a crown.
Tip 2: How to photograph a drop of water
One of the most creative and exciting types of photography - a photograph of water drops .A careful approach and patience, but you might have a brilliant shots, besides, you learn to understand the interdependence of aperture and shutter speed, gain useful skills to work with light.To take a picture drop water , you need a good camera and easiest props.
- - good camera;
- - States;
- - water tank;
- - flash or table lamp;
- - package, a plastic cup, a bottle of water;
- - colored background;
- - patience.
Select a location for shooting your regular table.In the background, place the background, rather monotonous to the flash light reflected better.On the table, put the feed tank drops, it may be a glass, a glass (possibly inverted), a saucer or bowl.
Set the flash on the side of the falling drops.The best option would be two professional flash synchronizer, but if such an opportunity you do not, use the powerful desk lamps, just slide them closer.Depending on the received frames change the location of the light sources so as to achieve the best effect.
hang over the table and well fix a plastic bag, a plastic cup, a bottle of drink, or other suitable container.Then do a small hole in it so that the water did not flow stream, and dripping with the right speed.
Install the camera at the fall of drops, while being able to use a tripod or other device for fixing (for shooting, you can use remote control).Click on the camera to manual focus.Then put in the place of the fall drops immovable object such as a pencil.Either put on the bottom of the container or gum eraser and plug it into the pin with a ball on the end or a toothpick.Place and lock the focus.
to increase the depth of field, close the aperture to F8-F16, but note that the aperture value depends on the shutter speed, so try different values depending on the results.
shutter speed or the shutter speed is set at a value of 1/160, 1/200 ... 1/1000.The higher the speed, the better the effect will freeze.
If possible, turn on burst mode, at the same time you have to get more good shots.Make every effort to increase the speed: disable noise reduction, do lock the mirror, etc.
Begin to shoot the falling drops, thus take a picture at a time when a drop of flying.Experiment with light, shutter speed, aperture setting.Do not lose your temper, you may have to make many attempts before you want the result.
use not only water, try different liquids: oil, watercolor painted water, milk.It is possible to combine different liquids such as milk let you dropped into water, or vice versa.
