Questions and answers plus examples to break the inherent mystery of the flash - flash tips

The younger brother is by no means a master of photography. With the qualifications and works of his younger brother, is he dare to write a so-called “tutorial” in front of you? Even if he has a swollen face and is full of fat people, he only dares to use his flashlight for months. Shallow cognition is summarized in the text. In view of my ridiculous level, the views in the text will inevitably leave the board, but also hope that you see Guan Haihan.

Special Note:

The term "flash" is used in this article to refer to both generic and collective names (including but not limited to hot-shoe overhead flashes, photo-shooting lights, studio flashes, etc.).

This article only discusses the use of flash in the use area of ​​portrait shooting. The viewpoint in this article does not fully apply to the field of studio shooting and still life photography.

This article discusses the off-camera wireless flash, the method of directly mounting the flash directly on the camera hot shoe against the subject is not within the scope of this article.

The schematic layout of the lighting is based on post-mortem recalls, so there may be slight deviations from the actual situation.

The common myths about the flash:

â—Ž Myth NO.1 - buy hot shoe top flash must buy the original factory?

Although the original factory in color temperature accuracy and quality than the auxiliary plant has an advantage, but a trip to the original machine at the top of the flash price can buy three domestic brands deputy factory machine top flash, and the outdoor lamp and the shed flash pressure is not the original Factory concept. Unless the money is burning, the deputy factory is adequately used.

â—Ž Myth NO.2 - play three lights up?

From a practical, portable and introductory point of view, one trip is enough.

However, if you have a sufficient budget, or want to be more comfortable in the future, then I suggest you buy at least two.

And the specific configuration of the two flashing lights should be:

A high-powered outdoor lamp that can be used both indoors and outdoors with modeling lights, such as Shenniu AD600 â–¼

God God (GODOX) AD600BM manual version Bao Rong mouth lamp 600W high-power lithium high-speed synchronous flash wedding photography lights 2675 yuan Jingdong direct link GODOX Shenniu AD600BM AD600 camera dome light off flash 8000 high-speed wedding photography lights outside lights AD-H600B split lamp (Paul Rongkou) 260 yuan Jingdong direct link Sacred cow AD600 AD600M Flash Special-purpose Outer bag Portable Waterproof Wearable Perspective Panel 55元天猫Select Direct link

AD600 from the version, there are differences between the Pauline bayonet and Shennui bayonet, and with the difference between TTL and manual version, subdivided down there should be four different versions, the younger brother personally recommended compatibility better, more cost-effective AD600BM, which is the manual version of the Bao Rong bayonet. In addition, split lamp holders and carrying cases are also indispensable to buy.

A fast hot shoe flashback, such as the Shenandoah V860II

Lithium battery has the advantage of fast return, do not carry a bunch of 5 batteries, of course, if you have a bunch of "love wife", then the 5th battery version of the V860II, the Shentitiu TT685 may be a more appropriate choice â–¼

A wireless flash device, such as the Shenniu X1T â–¼

Godox X1T-C Flash Trigger High Speed ​​Synchronous TTL Trigger 2.4G Wireless Flash Trigger Canon Single Transmitter 215 Yuan Jingdong Direct Link

With this little flasher, you can remotely control and flash the entire range of Shenniu products as long as they have a built-in X wireless flash system.

Why is the AD600BM I recommend to you for the outdoor exposure light, not the AD360II, which is easier to carry?

In the case of a small price difference between the two, the AD600's power is 600W, while the AD360II's power is only 360W;

AD360II is Shenniuka mount, which is far inferior to the AD600BM of Baorong mount in the compatibility of accessories;

AD360II does not have modeling lights. Although the progress of technology has enabled the current mainstream flagship cameras to reach the focus of the -3 or even -4EV, so that these models have confidently removed the auxiliary focus lights on the fuselage. But if you are a night-time enthusiast, try to focus in the extremely dim light conditions, you will know how happy the flashing lights are! Of course, you can also try flashlight-assisted focus, but "focus open the flashlight - close the flashlight before pressing the shutter (because the flashlight is a constant light source, will become ambient light below the flash synchro shutter speed, and then affect the photo Exposure and Color Temperature Accuracy) - The workflow to refocus and turn on the flashlight is bound to be tedious and annoying.

Why do I recommend to you a combination of an external light + a twisting machine, not two or two?

The power of the external light is powerful. As long as it avoids the most intense afternoon light, the external light can be used for light compensation and outdoor calendering. This is not possible with the low-power overhead flash. If you want to achieve the full power output of the AD600, you'll most likely need about 8 feet of hot shoe flash with full power output. In view of this, plus the problem of the modeling light in the previous question, you should have an external light.

The reason why I don't buy two lights is just two reasons: it's too expensive to be worthwhile; it's too heavy to take any action.


If I bought at least two flashes as you said, wouldn't I need them every time I go out?

Most people do not have photography assistants, and even if occasional family or friends can act, it is also very abnormal. So if you think about using flashing lights when you are shooting, then the thing you must carry besides the flashing light is the light fixture with the flashing light â–¼

In principle, there is no one to help you. In the case of you and Madou, you have to carry several shelves with a few lights. This is not the worst case. Considering that the outdoor wind is easy to be blown off, the sandbags that hold down the lighthouse â–¼ are usually necessities.

The good news is that the sun will always serve as another light source (main light source, hairline, or edging light) for a sunny day, so if you are in good faith and you are determined to be lazy, take a trip. Lamps and an out-of-shelf shot are also available. Or there are some tricky ways. You can purchase a strong clip with a ball head to fix the top flash â–¼, but suitable and securely fixed places can often be encountered.

Another solution to reduce weight is to buy and carry a more compact, lighter folding flash bracket â–¼

The younger brother, every time I shoot outside, I take a shot of an external light plus a machine's top flash. I usually only carry a strong clip with a hot shoe light, which is similar to the program recommended for you. Unless there is a night view, the chance of using two flashes at the same time during the day is very low!

Shooting example a:

Lighting schematic â–¼:

Flash used:

The main light: Shenniu AD360II (At that time I have not purchased AD600BM) +80×80 portable softbox with S bracket ▼

Sacred cow Flash soft box 80*80cm With S Bracket lamp seat top outside lamp portable folding soft mask 160 yuan Lynx featured direct link

Shooting scene restoration: As shown in the lighting diagram, the sun forms a hairline at the position behind the two models, and the flashing lights are output at full power at the forty-five degrees to the left of the model. Due to some delays, I had to shoot near noon, plus the shooting location was at the top of the building. Therefore, the light is very strong, the shutter speed far exceeds the flash synchronization time, and only high-speed synchronization can be turned on. After the high-speed synchronization is turned on, the flashing power will be greatly depleted. Even if the full-power output is still underexposed by more than one gear, the problem of underexposure is solved by pulling the light up later.

â—Ž Myth No. 3 - The flash is used to shoot the night scene, no need to use during the day?

The flash is indeed a night vision artifact, but using the flash during the day can often turn into a magical. For example, you can shoot large backlit scenes, darken ambient light, add dramatic effects to people, add details to scenes, add color to scenes, change scene color temperature, create light and contrast, reduce contrast, and resolve underexposure. So, the real masters use flash lights during the day.

Shooting example two â–¼:

Lighting schematic â–¼:

Flash used:

The main light: Shenniu AD600BM + Shenniu 80CM portable octagonal soft box â–¼

Shenniu umbrella type octagonal soft box 80cm diameter portable soft cover dome light studio lights universal section 88 yuan Lynx featured direct link

Shooting scene restoration: The sun is close to the setting sun, and the grove is darker. I raised the sensitivity to ISO400 and deliberately extended the exposure time to increase ambient light. The sun is behind the beans and the back of the sun marks the hair of the beans, but if the light is not used, the beans will become a silhouette. The AD600BM is mounted in a portable club diffuser and placed on the left side of the beans. Because the ISO has increased to 400, the fill light has been made with extremely low flash power.

â—Ž Myth No. 4 - The effect of the flash is always unnatural and can be seen at a glance?

If the above two photos do not appear in this article, as long as the younger brother I do not say, basically no one will find two photos are used flash. Even if the younger brother has now turned the cards, there is still a glimpse of the younger brother's flash in the end where it is used (after the analysis of my shooting example will explain). It can be seen that if the method of using the flash light is sufficiently clever, it is not difficult for people to perceive the use of flash.

Shooting example three â–¼:

Lighting schematic â–¼:

Flash used:

Auxiliary light (hairline): Sacred cow V860II naked light

Shooting scene restoration: In fact, the above three photos originate from the same shot and the same shooting scene, just changing the angle of viewfinder. Due to the darkness of the entire staircase scene, Matou could not stand out from the scene, and the dark hair of the two Matou beans almost integrated into the stairs and the background wall. As usual, the younger brother is still fighting alone and without any assistants. The younger brother allowed two Matous to act as assistants temporarily in their own shooting interval. When the white T beans are shot, the black T beanballs directly hit the top of the stairs with the V860II naked light at the top of the white T beans, and vice versa. As a result, not only the hair of Madou had a hairline, but also the edge of the stairs at each level was illuminated. The texture of the wood wall on the right side of Madou was also clear. It was a stone with three birds. In short, under the premise of people not being aware of the use of flashing lights, the whole scene was completely vivid.

â—Ž Myth No. 5 - Reflector is enough during the day, but also what flash?

Reflectors do have the advantages of being portable, inexpensive, and easy to use. However, reflectors have many disadvantages compared to flash, such as:

It is difficult to use light reflectors to fill the characters without assistants, and the flash only needs one lighthouse.

The reflectors need to reflect the visible light source to make up for the characters. They can't be used in places where the light is dim;

It is difficult for the reflector to accurately control the intensity and brightness of the fill light;

Reflectors are dazzling, a torment for the subject and the model, but also make it easier to close your eyes and look unnatural


Under normal circumstances, the younger brother, I always carry reflective plates and flash at the same time, depending on the actual situation, or use them together, will get good results. Therefore, reflectors and flashlights are not a mutual replacement but a complementary relationship.

â—Ž Myth No. 6 - reflectors fill light better and more natural?

Today's reflectors are basically five-in-one or seven-in-one. If you fill the light with a white object, you can actually get more natural results. However, compared with gold and silver, white is very weak. And because there is usually a high probability that the reflector will reflect sunlight from the bottom upwards, it is very easy to make Matou from the fresh and beautiful girl into a ghost.

The younger brother does not exclude the use of reflectors. Instead, he is the lover of reflectors. But the younger brothers usually use reflectors to create a kind of drama tension and more exaggerated effects by using "devil light" from the bottom up â–¼

Shooting example four â–¼:

Lighting schematic â–¼:

Flash used:

Auxiliary light (fill light): Shenniu AD600BM+60×90 portable soft box ▼

Sacred cow 60*90cm Umbrella Portable Softbox Flash Universal Portable Dual-use Photography Soft mask Reflective umbrella 80 yuan Lynx Select Direct link

Shooting scene restoration: The sun outlines the silhouette of the figure and hair highlights on the front of the model. The flash fills the light behind the model, reducing the strong contrast due to direct sunlight and filling in the shadows. If you do not explicitly point out that it is actually not easy to find, the effect is much more natural than the photo using the reflector.

â—Ž Myth NO.7 - Soft light is very important! Don't use bare lights directly at any time?

It's more important to shoot than to shoot! When you have bare lights at hand and no soft light fittings, use naked lights boldly.

Soft light brings natural light effects, and bare lights can bring dramatic light effects, which are not good or bad;

Naked light can also get natural soft light by way of the ceiling or wall to make a flash.


The hard light effect brought by naked lights is actually very popular. You can see that Terry Richardson and Mihara Yone are very popular.


Shooting example five â–¼:

Flash used:

The main light: God cattle V860II bare lights

Restore the shooting scene: Directly align the lamp head of Shenniu V860II to the tin ceiling, use 1/2 of the power to make a jump, and solve the problem of insufficient light in the front of Madou. At the same time, because the naked light flash is a large area of ​​diffuse reflection, there is no hard light effect.

Shooting example six â–¼:

Lighting schematic â–¼:

Flash used:

The main light: God cattle V860II bare lights

Shooting scene restoration: Shen cattle Cattle V860II naked light from the right side of Ma bean direct flash, creating a dramatic effect of light and shadow contrast.

Shooting example seven â–¼:

Shooting scene restoration: The red cow's V860II naked lamp with red color piece is directed at Matou from the cupboard, and the other naked lamp with a blue color piece is aimed at the ceiling. A mysterious and strange atmosphere.

â—Ž Myth NO.8 - I am in a place where there is neither a river view nor an ocean view, no colorful skyscrapers, no fountains and light shows, doomed to take a good night view?

The basic principle of flash night scene is that the foreground dark background is bright, which means that the background is best colored with variegated light and shadow. It's true that it's better to take a picture of the night in a big city, but the same can be done in a small city of 18 lines. The younger brother's own skill is to march toward the downtown area or the bustling commercial district at night. It is easy to find good looking backgrounds in these places. Of course, the disadvantage is to eat melons and have a little crowd.

Shooting example eight â–¼:

Lighting schematic â–¼:

Flash used:

The main light: Shenniu AD600BM + Shenniu 80CM portable octagonal soft box auxiliary light: Shenniu V860II naked light + light blue flash color film

Shooting scene restoration: Matou COS is the Christmas love song of the king's glory and the shooting location is the rotating glass door of the Apple Store entrance in Shuncheng, Kunming. The main light uses Shenniu AD600BM+Sheniu 80CM portable octagonal softboxes to light Matou, and the other uses a Shenniu V860II naked light+light blue flash chip to create a bright and transparent effect on the glass door.

Shooting example nine â–¼:

Lighting schematic â–¼:

Flash used:

The main light: Shenniu AD600BM + Shenniu 80CM portable octagonal soft box auxiliary light: Shenniu V860II naked light + light blue flash color film

Shooting scene restoration: Similar to the above example, the difference is that the auxiliary light is replaced by a position.

Shooting example ten â–¼:

Flash used:

The main light: Shenniu AD600BM + Shenniu 80CM portable octagonal soft box

Shooting scene restoration: This example is more simple than the previous two examples, because the background is bright enough, so simply remove the auxiliary light, directly use Shenniu AD600BM + Shenniu 80CM portable octagonal soft box as the main light model light .

â—Ž Myth NO.9 - Flash can not enter the mirror, otherwise it will wear the help or the screen will produce glare and flare becomes difficult to see?

The rules are used to break it. This sentence is suitable for any work related to creativity. The younger brother often makes the lighthouse deliberately appear in the picture, so sometimes the opposite will add an extra interesting point to the photo. In addition, lens glare and flares are not necessarily all bad, and sometimes the opposite will add an extra atmosphere to the photo.

Shooting Example 11 â–¼:

Lighting schematic â–¼:

Flash used:

The main light: Shenniu AD600BM + Shenniu 80CM portable octagonal softbox auxiliary light (contour light): Shenniu V860II bare light

Shooting scene restoration: When this group of photos was taken, the time was close to midnight. As all the shops had already closed, there were only a few lights left in the entire street, which seemed dark. In order to allow Madou wearing a black T-shirt to jump out of the background, I purposely added a flash of light to highlight the silhouette of one side of the model and highlights at forty-five degrees behind him. Comparing the two photographs, it is not difficult for the officers to see that the second photo of the flashing light entry is more interesting, even if there is a lens flare.

â—Ž Myth NO.10 - Flash photography is difficult?

As long as you understand the relationship between aperture, shutter speed, and sensitivity and use full manual photography, congratulations, you have learned half of the flash photography! All you need to know is the flash sync time, flash power, and inverse square law.

The younger brother came up with a few simple flash photography introductory rules:

Turn both the camera and the flash to "M", which is a full manual file. The camera should not use the aperture priority. Do not use the TTL (except for news reporters who use the flash for snapshots).

Do not let the camera's shutter speed exceed the flash sync speed (Canon camera is 1/200 second, Nikon Sony should be 1/250 second, the camera with mirror shutter, for example: Fuji X100 and Hasselblad medium format is not subject to this limit). Of course, you can turn on high-speed sync, but the flash's power will decay very much;

With ISO, flash power and flash distance unchanged, you only need to remember the phrase “the aperture size controls the brightness of the flash, and the shutter speed controls the brightness of the ambient light”.

Adding any soft light device in front of the flash lamp head will at least cause the flash to lose one or more levels of power;

Try not to use full-power flash, as the flashback speed will be very slow and the battery life will be greatly reduced.

Finally, I wish you a pleasant use of the official lights. Use a lot of flashes to shoot your own works!
