The application of flash is varied. It can not only illuminate the image, but also match different light effects. However, it is not easy for the initially photographic users to master the skills of using many flash simultaneously, and it also takes a certain amount of money to buy multiple flash. So this time, Xiaobian will introduce you the skills of using a single light to shoot, from shallow to deep, and teach you the basic skills of controlling flash skills.
To understand the application of flash, we may start from different angles of lighting. Generally speaking, we can directly insert the flash on the top of the machine to illuminate the main body. Although this has been able to take accurate exposure of the main body, but generally such light angle light is easy to be too hard, and may even make the main body become a dead white, look very stiff. In order to make the light effect more flexible, this test is to let the user know how different angles will work, so this time we also use flash initiator to off-line control the flash.
In the test, we used a flexible umbrella to irradiate the model at about 0 45 and 90 respectively.
Case 1:0 Degree Direct Irradiation
The effect is that the light on the face is flat and the outline of the face is not prominent.
Case 2:45 Degree Side Shot
Models will have slight shadows near their cheeks, adding contours.
Case 3:90 Degree Side Shot
The model's face will be strongly shadowed, highlighting the line of the nose.
It can be seen that light from different angles will have different effects on the feeling of the picture. When shooting frontally at 0 degree, the line of the model's face is not prominent, and a strong contour line can be created on the 90 degree side. When the oblique light is 45 degrees, the effect is in the middle of the two. In this test, we only used a flashlight, and felt that the light on the model's face was more natural when the angle of 45 degrees was oblique. However, according to their own creative style, photographers can use the angle of flash flexibly to take pictures in their mind.
Light quality affects strength and hardness
Light quality means light of different properties. We can also understand the different "texture" of light. After choosing the appropriate illumination angle, the next step is to choose which form of illumination to use. In the above test, in order to be fair, we used a flexible umbrella to test the camera at different angles. In fact, in addition to the flexible umbrella, there are other light control devices on the market that can be used to regulate the nature of light. In this test, we used a flexible umbrella, a reflecting umbrella, a reflecting plate and nothing to test different effects by directly illuminating the model with a flash.
We placed the flash from the model's position of about 45 degrees to see what the different light quality would be. In the first test, we directly illuminated the subject with a flash. From the test photos, it can be seen that the effect of light is very strong, even a bit rigid, if not intentionally pursuing strong light, the effect may not be too ideal. Then, we added a soft umbrella to the front of the flash at the same angle. This time, the light came out very gently. The shadow of the model's face was not so strong. The light distribution was relatively average, and the effect seemed to be more natural than shooting directly with the flash.
Case 1: Flash direct
The light effect is so strong that it makes the picture look unnatural.
Case 2: Flexible Umbrella Effect
The light will be softer.
We shoot the model in the same position with a reflective umbrella. From the photos, we can see that the intensity of light on the model's face has increased, and the shadows on the nose bridge have become more obvious, but it is not as hard as shooting directly with a flash. Finally, in the same position, in front of the flash, we hold up the reflex board which is usually used to supplement the light, and let the light source reflect the main body to take pictures. The results show that the method of shooting with reflective plate and flexible umbrella have almost the same effect. They are as soft as each other, but the light of reflective plate is weak, but the distribution of light is more average than that of direct reflection and reflective umbrella.
Case 3: Effect of Reflector Umbrella Irradiation
The effect is similar to direct radiation, but not too strong.
Case 4: Reflector effect
The effect is as soft as using a soft umbrella, but the light is weak.
According to the test of light quality, if you want to have a stronger light contrast, you can directly use the flash to illuminate the main body, you can also use the reflective umbrella for shooting. However, direct irradiation, sometimes the effect of light will be too strong, so if you want to create an atmosphere like this, it is recommended to use a reflective umbrella more reliable. If you want to photograph a softer light effect, you can use a reflective plate and a soft umbrella to produce the same effect. However, generally speaking, if a soft umbrella is placed on the front of the flash stand, the shooting can be carried out, and the shooting process is relatively stable. The use of reflective panels may require one more person to cooperate with the shooting work, but the effect may be relatively flexible.
Single lamp calender
Many photographers know that flash photography can achieve a unique "calendering" effect. "Calendering" is the use of flash light to dim the scene while keeping the subject exposed correctly. We often see photographers taking portraits in the sunset in this way. But specifically speaking, the implementation method needs to have an understanding of the principle of "calendering".
When shooting with flash, we should pay special attention to the setting of the camera, the aperture controls the exposure of the main body, and the shutter is used to adjust the brightness of the background. First, we use shutter priority or aperture priority mode to set different aperture shutter values to target the sky for photometry, until we get the appropriate brightness of the background in mind. We then use the aperture and shutter values of the photos just taken as a reference, then adjust the camera to manual mode to input the values, and then start flash shooting.
In this photo, we put the flash on the top left of the model about 45 degrees. After the photo is taken, we adjust it according to the effect. Finally, we find that the effect of f/4 aperture shutter for 1/250 seconds is the most satisfactory, and different environments may require different shutter and aperture values to match. When shooting, we should cooperate with the position of the background light, which can be seen. This method can make the background of the picture darker, while the main body keeps the correct exposure. As long as you follow this method when you see the sunset, you will be able to take beautiful pictures.
Low Angle Shooting with Wide Angle Mirror
Understanding the basic use of flash method, then it is time to create real combat! In fact, in addition to different angles on the left and right, we can arrange the flash from different angles up and down. This time we connected the flash to a soft umbrella and placed it at about 45 degrees of the model. The difference this time is that we illuminate the subject from a low angle with a flash and shoot it with a wide-angle lens.
Using wide-angle lens and low-angle flash to shoot a model can highlight the foot lines of the model and reduce the direct shadow of the flash on the ground.
Using this method, we can see that the light below the model's body shines up. The light not only highlights the foot lines of the model, but also reduces the shadow of the flash directly on the ground. The effect is different from that of the normal flash from a high angle. Of course, if we want to highlight the model's facial contour, we can also set the flash to a higher angle, but this time it is purely creative, hoping to let you know the different methods and effects.
