Synchronizer for flashes: types and description

Photography can be done with a simple press of a button only in the hands of an amateur. If we are talking about professional and even studio photoshootings, then a whole complex of auxiliary devices comes into play, which allows obtaining the most profitable images. Another thing is that in this case the master controls all the components of the photographic spectrum not with his own hands, but with the help of modern adaptations. These include the synchronizer for flares, providing a single operation of the main unit with accessories. Manufacturers of photographic equipment produce different types of this device, which differ in the principle of operation and performance.

Synchrosholes

In effect, this is a cord through which the connecting signal from the flash to the camera is transmitted. That is, a reliable channel is realized, which can provide different bundle configurations. For example, this is a good option if you need to connect one camera to several flashes. The device is simple and inexpensive, but it has its limitations. The cord synchronizer for studio flashes is advantageous in that it does not require additional power supply. In the studio there are also no strict requirements for the organization of the shooting process - in particular, the remoteness of the flash from the camera can be thought out and optimized. But if we are talking about shooting in street conditions, then the problem arises of arranging the flashes taking into account the length allowed by the cord synchronizer. In addition, if you plan to organize a complex photo shoot with several flashes, then the abundance of wires can become a hindrance.

Radio synchronizers

Such devices are usually a pair of receiver-transmitter. On a special insert of the camera is installed trasmitter, and on the flash - the receiver. During operation, a signal is transmitted over the radio channel and the camera simultaneously fixes the frame along with the illumination. The radial synchronizer for flares is convenient in that it is able to work practically at any distance that a flash can theoretically be installed relative to the camera. Has its advantages and lack of wires. But there is a shortage of such models - for their work requires a separate power supply. In modern radio synchronizers, batteries and batteries are used. If cord devices gradually leave the market, then this concept develops and improves. So, already some models of cameras are equipped with radio receivers by default, and on outbreaks manufacturers provide convenient fixators for receivers.

Infrared Synchronizers

This option gives the user many advantages, but also has significant disadvantages. The advantages include the ability to work at a distance without the use of a cable. The signal is transmitted by the principle of infrared radiation and instantly receives a flash response. As for the flaws, the synchronizer for flares of this type is extremely sensitive to operating conditions. Light radiation unpredictably behaves in conditions of sunny weather, so most infrared equipment is used in a studio where the influence of external factors can be minimized. Another unpleasant aspect is that flashes working on this principle react to any infrared signal and can ignite from each other.

Models from Yongnuo

Under the brand name Yongnuo come out good devices for flares of Canon. The manufacturer focuses on the production of radial models. In particular, transmitters with E-TTL technology provide high-speed synchronization of modern Canon cameras. For ease of operation, the company provides a remote control that allows you to monitor the shooting process at a distance from the equipment. As for the range of action, the synchronizer for the Canon flash works within a radius of 100 m. The highlight of the models is the autofocus illumination, which is important in conditions of poor visibility.

Models from PocketWizard

Specially for Nikon high-tech model offers firm PocketWizard. In its lineup also dominate the versions of synchronizers, the principle of which is based on the radio signal. By the way, premium models have the ability to communicate through 35 channels, which significantly expands the range of capabilities of this device. In addition, the range of such models deserves attention. For example, the synchronizer for the Nikon flash in the FlexTT5 version is capable of serving photographic lighting devices at a distance of about 300 m. Of course, such high performance can not be cheap. Synchronizers of this level cost around 10-15 thousand rubles. For comparison, the simplest cord and radios are estimated at 2-3 thousand rubles.

Models from Pixel Soldier

Sony produces cameras with a special design for the place of installation of synchronizers, therefore, not every accessory will suit this technique. Nevertheless, a suitable synchronizer model can still be found. These include Pixel Soldier products. Most versions working on the radio channel support a frequency of 2.4 GHz and require a battery for power supply. The disadvantages of the synchronizer for the flash of Sony can be attributed not the most solid range - about 100 m. In addition, the number of channels rarely exceeds 15, although there are premium versions that support a larger spectrum. The main attractive aspect in such synchronizers is the cost. Completely functional, even by modern standards, products can cost 3-4 thousand. Of course, as noted above, they are not as rich in performance as, for example, the PocketWizard, but for semi-professional shooting is quite suitable.

How do I make a synchronizer for a flash with my own hands?

To create a modern device that is similar to full flashes, you can either take an old synchronizer model, or build an entirely new device. Usually in both cases use the construction of circuits of transistors, to which a voltage of about 30 volts is applied. The circuit is powered by a current that comes from the synchrocontacts of the flash. In the process of work, a self-made flash synchronizer provides for the cashing of the voltage by a ballast resistor. In this case, it is necessary to provide filtering of the current with the help of a capacitor. Actually, in the construction and implementation of such schemes there is nothing complicated. Moreover, in some cases, provided high light sensitivity is achieved, the synchronizers can withstand the risks of distortion of the operation of flares due to changes in natural sunlight. By the way, interference can also occur due to improper artificial lighting.

Conclusion

Manufacturers of synchronizers of different types are trying to optimize the interaction models of these devices with cameras and flashes. Unfortunately, as the technological qualities and functionality of models increase, their responsibility for the quality of shooting increases. For example, a synchronizer for a Yongnuo flash, with proper control and connection to a Canon machine, can ensure the quality of the image at a professional level. However, the slightest error can easily damage the frame. That is, much depends on the human factor, even in the work with automatic equipment. On the other hand, developers add new devices that simplify the connection and management of photographic equipment. At the same time, the basic characteristics of synchronizing equipment are expanded, including range, remote control capabilities, as well as the number of individual and common radio channels.
