Photography flash trigger problem, how to keep the photography flash on

Friend, you should be using a Canon camera, and the model is not clear, because some models come with a set-top flash, and some do not, but I will try to help you as much as possible.

There are two ways to trigger the flash, one is to bring your own on-camera flash or install one, and then use the on-camera flash to trigger the external flash.

Another way is to install a wireless flash trigger, some machines come with a wireless transmitter, see if there is this function in the instructions.

However, it is important to have wireless (off-camera) flash on the camera itself, otherwise synchronization will be problematic. The flash must have a wireless (off-camera) function and channel settings.

Sometimes only one external flash can be triggered by a wireless transmitter, but it is no problem to use 580 for all, because 580 comes with a wireless transmitter and frequency setting.

In addition, if you use the on-camera flash to trigger the flash, it can trigger multiple flashes without limitation, but there is one thing that must be noted that the flash used must have a wireless (off-camera) function setting.

Please read carefully whether the camera and flash functions are compatible with off-camera flashes.

If you want to flash a Canon flash, you must use a Canon original flash trigger, and three lights can flash at the same time.

You can also use the 580 to trigger two 430s without the need for a trigger. Look carefully at the instruction manual of the lamp to know how to set it.

Summary. Professional camera flashes don't stay on because of their working principle, which stores electricity and then instantaneously emits light emitters (some are special diodes). If you want the camera to have a continuous lighting source, it is recommended to start with an LED light, ** is also very cheap, there are rechargeable batteries, and there are also dry batteries.

The solid LED light can be plugged directly into the camera's hot (cold) shoe. As long as you turn it on manually, there are LED lights on the market, there are that kind of row lights, and there are also that kind of ring lights that are always on. Hope it helps.

Hello, it's a pleasure to be here with you, I will try my best to find you back and answer your questions, please be patient, thank you very much, thank you for your understanding and support.

Is it the flash of the mobile phone or what kind of equipment?

Sacred cow flash.

At the beginning of shooting, it is lit, and when you will shoot, it will not be lit, but you can shoot flashing.

Professional camera flashes don't stay on because of the way they work, which is to store electricity and then use the luminaries (some are special diodes). If you want the camera dust to have a continuous lighting source, it is recommended to start with an LED lamp, ** is also very cheap, there are rechargeable batteries, and there are also dry batteries. The solid LED light can be plugged directly into the camera's hot (cold) shoe.

I don't think so, but if it's a professional, it's not okay.

Through an external wireless signal transmitter, the transmitter is installed on the camera's hot shoe or flash cable interface, and the receiver is installed under the flash shoe, and then the same communication channel is set, so that when the camera presses the shutter, the flash can be controlled wirelessly.

The scientific name of flash is flashlight. Flash is also one of the ways to enhance the amount of light, especially in dim places, turning on the flash bridge to open the light can help make the scene brighter. The full name in Chinese"Electronic flash light sensitive years", also known as high-speed flash.

The electronic flash lamp stores high-voltage electricity through a capacitor, and the pulse triggers the flash tube to discharge it, completing the instantaneous flash.

Hello landlord: According to your general situation, I estimate that the following points may be 1Caused by loose batteries inside the trigger. Solution: Manually unscrew the screws on the trigger to install the battery from scratch.

2.Check the plug of the trigger receiver to see if it is loose or broken, and see if the battery is loose. Solution: Replace it with a new one.

3.Is it good to use manual flashing? Doesn't that girl flash when you press it? If it is not easy to use manually, it is more of a matter of triggering the transmitter. Solution: Same as 1

When shooting with a flash, the flash flashes for a very short period of time, usually just a few ten-thousandths of a second.

Therefore, the length of shutter time during flash shooting does not work.

However, for a DSLR with a curtain shutter, there is a flash sync speed. Below this speed, the curtain door is wide open. Higher speeds are used to reduce local ** time by reducing the gap in the curtain.

At this time, with flash, the picture will be half bright and half dark. Therefore, when using flash for SLR, the shutter speed must be lower than the flash synchronization speed.

Each flash has a flash index indicator, which is equal to the number of apertures multiplied by the distance of the flash from the subject when shooting with a single light.

For example, for a flash with an index of 20, the camera should shoot at an aperture when the flash is meters away from the subject. If you use an aperture, you will be overexposed, and if you use an aperture of 11, you will be underexposed. If the distance is 5 meters, the aperture needs to be increased to.

You're using multi-light shooting, and you generally can't use Smart Flash Control.

To solve flash overexposure, the solution is as simple as closing the aperture (increasing the aperture index value) or closing the distance between the flash and the subject.

It stands to reason that multi-lamp flicker should be used with TTL function, and the lamp itself can intelligently control the brightness of the light, obviously your lamp does not have this function. In this case, the camera shutter is set to 200 to the limit, otherwise there will be half black and half bright as you said, because the principle of the shutter itself is limited. You can find a way to dim the light, such as keeping the light away from the subject, or thickening the light box cover, etc., toss slowly, I wish you success.

Shutter setting questions to see what is your camera's flash sync shutter? 1 60 try.

I've just used the flash, and the situation you mentioned appears that the flash is still charging, and it's completely normal for this to happen. After a while, the charging is over, and it is back to normal.

If the flash is turned on, but the flash has not been used, and this high situation occurs, it is a detection circuit of the flash charging that has a problem, and it has to be sent for repair!

Take a look at the flash and check the flash settings first! If it doesn't work, take it to a repair point!

But it's not very nice to take pictures with a flash, unless you want a special effect! I don't have a flash on my camera!!

The first is the simplest contingency.

It's that there is an "easy" easy photo option in the menu where you set the scene mode, and when you choose this mode, it is a fully automatic point-and-shoot shot, if the scene is too dim, it will automatically fire, and the amount of flash is also automatically controlled.

The second is to explain to you that the "High Sensitivity Mode" is designed for situations where flash cannot be used in museums and theaters, and you choose this mode to disable flash to the opportunity and turn on the maximum sensitivity, so if you want to use flash, you can't use this mode.

The next step is a more professional plan. Or the Qin Jue mode selection interface,"Easy"There is also a "PGM" program automatic mode next to it,Turn on this mode first,Click flash mode on the main interface,Select the second forced flash。 If the flash move does not meet your requirements, click on the menu menu under the 2-3 page of the first item, Flash STD, and select the third option to increase the flash output.

If you still feel that the flash is not bright enough, sorry friends, this is already the limit of your own camera, the night shooting effect of this small camera is very poor, and it has been a long time, you can consider changing to a new one

When the flash does not turn on, it is recommended to try the following methods to solve the problem:

1. Please confirm whether the battery of the mobile phone is sufficient. When the battery is too low, the flash is turned off by default, and it is recommended to charge it above 20% before trying.

2. If the flash auto mode is turned on, the camera will automatically turn the flash on or off according to the ambient light intensity. To use the flash in a well-lit environment, turn on the forced flash mode, and the flashing light will always be turned on when taking photos or videos.

3. If the flash is overheated or used too frequently, the flash may not be able to be used when the temperature of the flash is too high, please try again after a period of time.

4. Please open the background to confirm whether some code scanning software is used, resulting in the flash cannot be used. Please close the relevant software before turning on the flash lamp. Enlarge.

I think there may be three reasons for this problem.

1.The reason is relatively simple, as the flash takes time to recharge. The principle of the flash is to send the electricity of the battery to a large capacitor in it, the capacitance is very large, the largest is the size of a No. 1 battery (such as the flash of Leica SF64), it takes time to draw the electricity into the capacitor, the flash moment to discharge the electricity in the capacitor, and it takes a time to recharge after it is released, and there is no way to take pictures in this process.

Solution: The first way is to reduce the power of the flash a little bit and then shoot, for example, my flash index is GN64, then I turn it off to the power of 1 2, and it will become only GN32 to take pictures, so that I only discharge half of the capacitor, and it does not take much time to fill the remaining half. Some people will say, I just need a strong flash, I don't want to use the flash, what should I do?

For example, you only need to use the GN16 index flash, and then you don't buy the GN16 flash, but buy a flash with a large index of GN64, and then adjust its power to the original 1 4 to take pictures, so that the flash intensity is equal, but you only release the power of 1 4 in the capacitor, so that you can also get a relatively short charging time, and the flash can keep up with you when you want to shoot, and it can flash for you. This is the first thing that can cause the flash not to flicker.

2.You turn on the flash's autofocus assist light, what is this concept? This means that some flashes have a small white light or a small red light on it, and when you press the shutter halfway, it emits a beam of light to illuminate the subject to help you focus.

When I'm in a nightclub, I often find a red light coming out of my flash, because my camera can't autofocus, so it doesn't make sense to me. And the light it emits actually alerts the other person that someone is taking a picture of you, which will make the person being photographed appear contrived, so I turned off this light. Why might this feature cause our flash not to flash?

This is because some flashes cannot be fired at the same time when emitting a focus auxiliary light.

3.It's possible that it doesn't flash because you have a feature called "Auto Zoom" turned on. For example, when you take a picture with a wide-angle lens, the flash will work with you to use a wider range of light, and the lens group in the flash head will change a little to cast light in all directions, so that everyone you can see at the wide angle will be illuminated by the flash.

But if you use a medium or telephoto, it will make the light more concentrated, like the beam of a flashlight, and only illuminate a person in the distance. Sounds like a great feature, but if you're using a zoom lens right now, when you quickly twist the zoom ring on the lens from a wide angle to a telephoto (or vice versa), the flash doesn't zoom so fast that it can't keep up, so it may not flash at all.
