Photography can be done by simply pressing one button only in the hands of an amateur. If we are talking about a professional and even studio photo shoot, then a whole range of assistive devices comes into play, allowing you to get the most profitable pictures. Another thing is that in this case, the master manages all the components of the photographic spectrum not with his own hands, but with the help of modern devices. These include the synchronizer for flashes, which provides a one-time 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 operational qualities.
Synchrocords
In essence, this is a cord through which a binding signal is transmitted from the flash to the camera. That is, a reliable channel is implemented, which in this case can provide different configurations of the bundle. For example, this is a good option if you need to connect one camera with 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 the street, then the problem arises of the placement of 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 transmitter-receiver. The transmitter is installed on a special insert of the camera, and the receiver is installed on the flash. In the process, a signal is transmitted over the radio channel and the camera simultaneously captures the frame along with the lighting. The radar synchronizer for flashes is convenient just because it is able to work at almost any distance at which the flash can theoretically be installed relative to the camera. Gives its advantages and the lack of wires. But there is a drawback of such models - for their work requires a separate power supply. Modern radio synchronizers use batteries and batteries. If cord devices are gradually leaving the market, then this concept is developing and improving. So, already some models of cameras are equipped with radio receivers by default, and on flash units manufacturers provide convenient clips for receivers.
Infrared Synchronizers
This option gives the user many advantages, but also has significant disadvantages. The advantages include the ability to work from a distance without using a cable. The signal is transmitted according to the principle of infrared radiation and instantly receives a flash response. As for the shortcomings, the synchronizer for flashes of this type is extremely sensitive to working conditions. Light radiation behaves unpredictably in sunny weather, which is why infrared equipment is most often used in studio conditions where the influence of external factors can be minimized. Another unpleasant aspect is that flashes that work on this principle react to any infrared signal and can light up from each other.
Models from Yongnuo
Under the brand name Yongnuo come out a good device for Canon flash. The manufacturer focuses on the release of radium 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 control 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. Autofocus highlighting is also a feature of the models, which is important in poor visibility conditions.
Models from PocketWizard
Especially for Nikon, high-tech models are offered by PocketWizard. Its lineup is also dominated by versions of synchronizers, the principle of operation of which is based on a 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 radius of action of such models deserves attention. For example, the Nikon flash synchronizer in the FlexTT5 modification is capable of servicing photographic lighting devices at a distance of about 300 m. Of course, such high performance can not be cheap. Synchronizers of this level cost about 10-15 thousand rubles. For comparison, the simplest cord and radium devices are estimated at 2-3 thousand rubles.
Models from Pixel Soldier
Sony produces cameras with a special design for the installation of synchronizers, so not every accessory is suitable for providing such a technique. Nevertheless, a suitable synchronizer model can still be found. These include Pixel Soldier products. Most versions running over the radio support a frequency of 2.4 GHz and require batteries to power them. The disadvantages that the synchronizer for Sony flash have are 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 wider range. The main attracting aspect in such synchronizers is the cost. Products that are quite functional, even by modern standards, can cost 3-4 thousand. Of course, as noted above, they are not as rich in operational qualities as, for example, PocketWizard models, but they are quite suitable for semi-professional shooting.
How to make a synchronizer for flash do-it-yourself?
To create a modern device similar to the functions of full-fledged flash units, you can either take the old synchronizer model or assemble a completely new device. Usually, in both cases, they use the construction of circuits from transistors, to which a voltage of about 30 volts is applied. The circuit is powered by the current that comes from the sync contacts of the flash. In the process, a makeshift synchronizer for flashes provides for cashing the voltage with a ballast resistor. In this case, it is necessary to provide filtering of the current using a capacitor. Actually, there is nothing complicated in the construction and implementation of such schemes. Moreover, in some cases, provided that a high photosensitivity is achieved, synchronizers can withstand the risks of distortion of the flashes due to changes in natural sunlight. By the way, interference can also occur due to inappropriate artificial lighting.
Conclusion
Manufacturers of different types of synchronizers seek to optimize the interaction models of these devices with cameras and flashes. Unfortunately, as the technological qualities and functionality of the models increase, so does their responsibility for the quality of shooting. For example, a synchronizer for a Yongnuo flash, when properly controlled and connected to a Canon device, can ensure professional-quality picture quality. However, the slightest mistake can easily ruin a frame. That is, a lot depends on the human factor, even when working with automatic equipment. On the other hand, developers are adding new devices that simplify the connection and control of photographic equipment. Along with this, the basic characteristics of synchronizing equipment are expanding, including the range, remote control capabilities, as well as the number of individual and common radio channels.
