Getting To Know An Intervalometer

The world indeed is a beautiful place that has numerous beautiful sights, some natural while some man-made. With photography it is now possible to capture this beauty with a camera.

With the advent of technology, photography enthusiasts have been able to improve the quality of the pictures they click. One such device that helps them to do so is an intervalometer, which is basically a device plugged into a camera for counting intervals of time. In photography time is of essence. The quality, creativity and aesthetics of a picture depend on whether a picture was taken at the right moment. A delay of even a split second may cause a photographer to fail in capturing the right moment. These devices are usually used to indicate or signal other devices to start an operation at specific time intervals. For instance an intervalometer might activate another device after every thirty seconds. It finds ample application in various fields that even includes military operations.

As far as photography is concerned, these devices are mainly used for bringing out exposures, usually in a time lapse series. Exposures are basically the quantity of light that is allowed to fall on each unit of the area of the medium being photographed, typically an image sensor or a photographic film, during the process of taking a photograph. More often than not, the objective of using this device is to cut down on the resources one requires to either take a picture or to post-process it, as similar photographs can be obtained by enabling the camera to take photographs as quickly or fast as possible. The use of an intervalometer allows the restriction of the photographs taken to only those which have the required content. This does away with the need for resources such as storage media like a memory card.

Apart from being used for triggering exposures, these devices are also used for various other purposes in photography. To start with, people can shoot images for stacked compositions with it. It can even be used for capturing blurred images with long shutter speed.

For taking delayed shots or even creating self portraits where the camera takes one picture every 1.5 minutes or even every second, exactly like an iPhone's Photobooth app. For that matter, as usually DSLR cameras are confined to shorter exposure of roughly thirty seconds or even less, they use an intervalometer to take shots with exposures of longer than thirty seconds, with the 'bulb' in the device. In fact, very long exposures can also be managed to take shots at night and create effects like star trails, animation or even astro-photography to showcase the effect of heavenly bodies in the sky at night like a nebula or a galaxy. These devices also find application in aerial photography which includes delaying the time required to take a picture by an unattended camera of a moving vehicle or body.

The intervalometer has, undoubtedly, improved the scope of photography by leaps and bounds.

The intervalometer isn't the only add-on to your setup that you'll find useful. A matte box can really make a huge difference if you are suffering from light issues.
