A DSLR flash, does a DSLR need a flash?

A DSLR camera with a flash is necessary. Flash is a kind of supplementary light device, which can ensure the clarity and brightness of the picture in dim conditions, and when shooting outdoors, the flash can also be used as an auxiliary light source to emphasize the tone of the first day. Special effects can also be arranged according to the photographer's requirements.

The key to buying a flash is to determine what type of flash you need and how many functions it has. Generally, the small size, light weight, and low power consumption of the flash are loved by everyone, and the right is cheap and has a wide variety, which is very suitable for professional and amateur photographers. Depending on the situation used, the photographer will choose a lamp with a high index.

The functions and advantages of the external flash of the SLR are as follows:

1. The built-in on-camera flash of the SLR camera is folded and placed on the protrusion of the pentaprism on the top, and the height of the lamp head is limited. When a DSLR camera uses a telephoto lens, the larger lens and its hood block the light emitted by the on-camera lights, causing a dark arc in the lower part of the frame.

But with an external flash, due to its sufficient height, the long lens and its hood will not block the light.

2. The built-in flash of the SLR camera is powered by the body battery, and considering the power consumption, the general flash index is only about 8-12. In the export talks, the flash is loaded with 2-4 AA batteries, and the flash index is as high as about 24-60, which has a large lighting distance.

3. The lamp head of the SLR camera with its own flash cannot be rotated freely, and the lighting direction is always facing straight ahead. The single-light frontal lighting of portrait photography tends to lose the three-dimensional effect of the face, and pesky shadows appear in the background. The head of the external flash can be rotated up and down more than 90° to create a lighting atmosphere similar to natural light, adding dimension to the face of portrait photography, and effectively preventing background shadows.

It is possible with a PC terminal. However, advanced features such as e-TTL or i-TTL are not supported, except for Sony, Canon, and Nikon, which can use the information point shield to reserve the center trigger point interchangeably.

The flash of a DSLR camera cannot be used universally.

Every brand of hot shoe design is different, so it's impossible to use a universal flash. Even different models of DSLR cameras of the same brand are not universal.

Here are the different brands of hot boots: 1, Canon, 2, Nikon Leica, 3, Fuji Panasonic Olympus, 4, Sony, 5, Sony.

Many brands are not compatible with other brands.

Not universal. Different voltages should not be used indiscriminately.

The flash operation of different cameras is slightly different, see the instruction manual of your own camera for details, the following is a camera flash instructions: If you don't know how to use it, you can choose "automatic transmission", or use "point-and-shoot camera" or operate according to the manual, the general flash is suitable for use when the light is too dark, and it is effective for people at close range (3 5 meters), and it is generally ineffective at long distances. FYI.

Flash: For DSLRs, flashes are like"The second sun", which matches the characteristics of DSLR cameras very well. While the flash illuminates the subject, it also has many other functions.

Flash is also effective in bright scenes.

If you want to shoot your subjects brightly in a dim environment, you can increase the ISO sensitivity, but a flash is preferred. The light hue of the flash is close to that of daylight, illuminating the subject while also rendering the subject exactly with its pure light quality. Since the flash flash time is very short, it can also freeze the subject's motion.

When shooting indoors, even if it looks bright enough, the actual shooting will often be dim, and sometimes it is difficult to adjust the right tone with indoor lighting. The flash makes it easy to illuminate the subject while eliminating the need for complicated tonal adjustments. If you master the features and functions of the flash, indoor photography will become more enjoyable.

How to operate flash photography.

Illuminates people without changing the brightness of the background.

The flash can be used not only as a primary light source for indoor photography, but also as an auxiliary light source in scenes such as backlit or window edges. In backlit conditions, the subject is often darkened due to background brightness. Of course, we can brighten the subject with ** compensation, but this may result in a noticeable reduction in shutter speed.

In such a scene, it is more appropriate to use an auxiliary light (flash) of the same intensity as the background light to brighten the dark parts than to use ** compensation to barely achieve brightness. This method also works well in backlit outdoor scenes. One of the techniques that is perfect for taking commemorative photos in scenic spots and other places is to keep the background bright, while keeping the background bright, but also to shoot the subject in front of you.

Adjusting the amount of flash light will bring a noticeable difference in the brightness of the picture.

When shooting with the flash as the main light source, the brightness of the subject depends on the amount of flash fire. If it is found to be too dim or bright during playback after the test shot, the brightness should not be adjusted by using the camera's ** compensation, but by increasing or decreasing the amount of flash, that is, adjusting the flash ** compensation, the amount of light received by the subject. Although the compensation also has a certain adjustment effect, the effect is not very ideal due to the problem of the algorithm.

Adjusting the amount of flash is more straightforward, and the brightness changes are more noticeable.

How to set the flash compensation.

The effect of flash ** compensation.

Brightness adjustment during flash photography should be done by flash** compensation. Select the appropriate value based on the reflection of the background and the brightness of the subject.

1. The built-in power of the SLR is small, the external power is large, and the functions are multi-point, such as softening, etc., which is easy to adjust.

2. The external lens is far away from the lens, and it is not easy to get out of the eye and the large lens to block the flash area.

Flash;

1. Use a flash to fill in the light when the light is low.

2. When the color is cast, you can use the flash to correct the color.

3. When the contrast is large, you can use the flash to reduce the contrast.

You don't need a flash to shoot night scenes, but be sure to use a tripod. In addition, this is true for night scenes, but if you want to take pictures of people in night scenes, you will definitely need flashing lights. (In order to ensure the night scene effect, slow shutter speed + flash should be used).

Ring flash: The full name is ring flash. As the name suggests, a ring flash is a highly professional flash that is mounted in front of the lens and is shaped in a ring or in a ring arrangement.

It is generally used when shooting macros. Generally, DSLR cameras can be configured with ring flash. The macro effect has nothing to do with the model of the camera.

There are also photographers who use high-power ring flash for portrait shooting, the purpose is also to eliminate the ordinary single-point flash direct light to leave a clear outline shadow on the back of the portrait, and the ring flash can also leave a circular eye light.

Ring flash is mainly used for macro shooting, because most macro lenses need to be very close to the object to have a macro effect, and if you use a normal overhead flash, the lens itself will be occluded, so the object will not be illuminated or illuminated unevenly. In this case, you can use ring flash to get even lighting.

A camera flash is an electronic flash, which is called flashlight in English. Flash is also one of the ways to enhance the volume, especially in dim places, playing flash can help make the scene brighter. The full name in Chinese is "electronic flash", 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. The color temperature of a typical electronic flash is about 5500K, which is close to the color temperature in the daytime sunlight, and the luminous nature is a cold light type, which is suitable for shooting objects that are sensitive to heat. Flash;

It is a photographic accessory that emits strong light in a short period of time and is photosensitive for photography. It is mostly used for instantaneous illumination in low-light occasions, and is also used to fill in the light of the subject in brighter occasions. Small size, safe to use, easy to carry, stable performance.
