How to release the flash after taking off the sled? Radio or cable? Which solution is safer? Which cheapest and most effective?
Not so long ago we reported on a new lamp to Canon – Yongnuo YN686EX-RT. Such equipment can be mounted on the camera sled, but this is not necessary. If you already know how to use the flash mounted on your camera, you may want to take it off for more interesting effects. See what you can unleash a lamp taken from a sled.
The photocell is the simplest solution. The undeniable advantage of this solution is the fact that it is free of charge. To trigger a reporter's lamp in this way, it is enough to handle the flash firing. Then, using the built-in flash, we can release the lamp on the tripod. Be sure to set the built-in flash to minimum power to minimize the impact on the picture. However, this solution has some drawbacks and limitations. First of all, we will have another flash in the scenery that can be seen in the shot. Second, the reporter's lamp must see the flash , otherwise it will not light up. It is very possible that in situations where we will take pictures in the sun the lamp will not read the flash and will not flash. An important limitation is also the time of synchronization with the lamp . In many cameras it is longer than 1/200, which is not useful on a sunny day. The photocell will also not transfer any automatics to the lamp.
Synchronization cable is also a cheap way of releasing the lamp, because the simplest model you can buy is less than a few dozen . The undoubted advantage of such a solution is that it can carry out the automatic control of the lamp and also does not generate additional flash and can trigger the lamp under any lighting conditions. Unfortunately, this solution also has its drawbacks. The basic is the reach – the lamp will be pushed away as far as the cable will allow. Besides, in this way we will release only one lamp. When we want to release another we will have to do it by a photocell – luckily, just flash from the secondary lamp, no need to use built-in.
The best solution is to use a radio trigger. The [YongSuo YN560-TX] release [YongSuo] YN 560 III or IV version, which has built-in receiver of this transmitter, can be an example here. It is worth mentioning that version IV has a built-in transmitter. For lamps that do not have receivers we are obliged to buy them. Keep in mind that this is the surest solution, carrying all the automatics offered by the TTL and HSS lamps. By using such a controller we can also change the manual flash parameters from the camera or the transmitter itself, without having to approach the lamp. This solution also has one serious minus – it is the most expensive of all three . The proposed relatively cheap Yongnuo drivers will work with this brand of lamps, with others not necessarily. Such transmitters are the cost of several hundred zlotys. Once we know all the solutions we can choose one particular. I would rather not recommend buying a synchronization cable because of the limited range. In addition, if you want to put the lamp behind the object, there is a chance that we will not hide the wire in the frame. At first I suggest trying with photocel – despite its limitations it is quite an interesting solution and above all does not require a financial contribution. When it turns out that remote flashing is what we want and additionally we will not be able to suffice this solution we can replace them with transmitters.
