Take Your Photography To The Next Level With The Proper Flash
Not all that long ago, the main problem of photographers is how they can obtain enough light in order to vividly capture an image situated in a dimly-lighted area. Because of this problem, camera manufacturers have developed the use of flash. The camera flash is considered as one of the most integral part of this popular photography equipment. This camera part is used to create a burst of artificial light which helps further brighten a particular scene. The artificial light create by the electronic flash is usually measured at 1/1000 to 1/200 per second. The flash had been part of the photography process for a very long time: starting from the primitive disposable flash bulbs and incendiary powders to the electronic models that are incorporated in the cameras nowadays.
Typically, electronic flash is already installed in the main body of most standard personal cameras nowadays. This helps users, who are not into expert photography, avoid the hassle of removing and attaching separate flash components. However, professional photographers (individuals and photo studios) usually prefer separately packaged flashes for their photography sessions. They often use flash units that are attached to the SLR camera through a hot shoe (or accessory mount) or stand-alone flashes (commonly known as studio strobes). Studio strobes are often powered through batteries or the power plug. In order to use this, studio strobes are coordinated with the camera through radio or light-triggered signal which allows synchronized operation of all separate camera components.
The basic flash system of a camera consists of three basic parts: the battery, the gas discharge tube and the circuit. The battery is the source of power for the flash system. The battery, when connected to the circuit (which is also connected to the gas discharge tube), pushes the flow of electron from terminal to terminal. This movement of electrons is what is powering up the device.
Among the three components, the gas discharge tube is the most unique since this is what generates the flash. The tube is composed of electrons on each end, metal trigger plate in the middle and is fully packed with xenon gas. The movement of electrons resulting from the battery power excites the xenon atoms placed in the tube. The metal trigger causes the strong attraction of electrons in the xenon atoms and initiates the ionization process. The continuous movement of the xenon generates the visible burst of light that is called flash.
Despite the benefits that photographers can derive from the use of flashes in their creative work, there still exist several limitations and drawbacks from its use. Usually, the flash is the only light source for photographers who take pictures in dark areas. As a result, shadows will not be shown in the picture. This can be resolved through stabilizing the intensity of the flash and natural light. Photographers can also use soft box or umbrella in order to allow shadows to be present.
The use of flash is also the culprit behind the red-eye effect in developed pictures. The red-eye effect result from the reflection of the human eye’s retina of the straight light (from the flash) that it receives. Most cameras now have red eye effect reduction option that can be activated to reduce this problem. Photographers can solve this problem through using flash units that are not detached from the camera unit. Through this, the red eye effect is eliminated since the flash is bounced off the reflector or the wall.
Cameras that have fixed flash units can only generate low-level of flash intensity. This flash intensity will not be sufficient for taking pictures that are more than 3 meters away from the camera. Instead of showing a clear image, the resulting picture will be grainy and noisy. This problem can be solved through taking pictures at the recommended distance of the camera manufacturer or by using separate flash units that have higher light intensity.
