How to adjust the exposure of digital camera?

1, take a close-up of something that is still very small, such as flowers, birds and insects;

When using Av files, the aperture should be below f5.6 and the focal length should be above 50. Try to shoot the blurred background within 1m!

Iso100 if the light is good; If the light is not good, iso is better within 400.

2, shoot people:

Basically, we use a larger aperture (within f5.6) and a focal length of more than 50 mm The shooting distance depends on the whole body, chest circumference and large photos, so the background is blurred and Av files are used!

Good light, iso 100, poor light, within iso400.

People in motion use chasing to express their sense of motion (see the shooting of moving objects below for details)!

Step 3 shoot:

For Av files, use an appropriate aperture, above f8, and the focal length is arbitrary, but generally the wide-angle end is distorted, so use it as appropriate.

4. Look at the night scene:

Install tripod, Av gear, custom white balance or incandescent lamp. Aperture above f8 and small aperture can make the light show starlight effect. Use the pre-lifting function of reflector to reduce the machine vibration caused by the lifting of reflector after pressing the shutter. Cover the viewfinder with a square cover on the strap to prevent stray light from entering from behind and affecting the drawing; Within iso200, let the exposure time be as long as possible, let some people who have no intention of walking disappear from the picture, leave no trace, and purify the scene!

For example, if you take a photo of a square, you can use a very small aperture of about f20, iso 100, so the exposure time will be very long, so the walking figure will not stay in the photo! The square will be clean!

5. Set off fireworks:

Using the cable release and B shutter, you can shoot the effect of multiple fireworks overlapping!

6. Shooting execution:

Good lighting: Av files, aperture size should be handled properly; A large depth of field effect can be obtained with an aperture above f8, and a shallow depth of field effect can be obtained with a small aperture.

If you want to shoot a very dynamic effect, you can use a TV file. The shutter is about 1/30. When you press the shutter, the lens moves behind the object at a suitable speed, which will produce a very dynamic effect!

Poor lighting: only handle it as appropriate, plus the use of chasing!

7, shooting running water or fountain:

Using TV files, the shutter speed is about 1/50, and the satin effect can be taken. If you use the shutter too fast, the fountain will shoot discontinuous water droplets!

8. Portrait at night:

On the tripod, adjust the white balance, automatic or custom white balance; iso 100-400； Av file, aperture f8 or so, adopting slow synchronous flash and Hou Lian flash mode; At this time, the flash will flash twice, press the shutter to flash once, and it will flash again before the exposure is over, so people should not leave before flashing twice.

This can make the characters clear and the background neon beautiful, so that the background will not be underexposed or too dark.

Av aperture priority skills:

I wish you happiness!

Brief introduction of SLR how to adjust exposure compensation

When we are shooting, we always hear people say that our photos are underexposed or overexposed. For photographers who are new to the camera, they often just know how to extend and shorten the exposure time, or open and narrow the aperture to correct this "overexposure and underexposure". However, the result of this is often more and more confused in the face of exposure. In fact, for exposure, there has always been an important saying in the camera, which is exposure compensation. Exposure compensation is not a verb or an action, but a name. Exposure compensation is a parameter used to quantify the brightness of photos. The reason why we can see everything in the world is that light shines on objects and then reflects into our eyes to become an image. If extreme white reflects 100% of the light, then extreme black completely absorbs the light and reflects 0%. Gray between extreme white and extreme black does not reflect 50% of the light as we thought. After precise measurement by scientists, the gray in the middle actually reflects 18% of the light. So the brightness in the middle is also called 18 degree gray. ▲ Different brightness and 18 gray. If we use the camera AUTO to take photos at different times and in different scenes, we will find that although the light intensity is very different, the brightness of the photos taken is not very different. This is because the camera will set the corresponding aperture, shutter and sensitivity according to the metering system when it is in automatic mode, thus taking a photo of 18 gray-not too bright, not too dark, just right. If we quantify this just-right brightness, the exposure compensation for such a photo with medium brightness is 0. ▲ For a photo with exposure compensation of 0, the exposure compensation of general cameras ranges from -2 to +2, and that of some high-end cameras ranges from -3 to +3. If shooting the same scene, the brightness of the photo with exposure compensation of-1 is half that of the photo with exposure compensation of 0, and the brightness of the photo with exposure compensation of -2 is 1/4 of the photo with exposure compensation of 0. On the other hand, the brightness of photos with exposure compensation of+1 is twice as high as that of photos with exposure compensation of 0. For many scenes, 18 gray is not a good brightness. For example, if we shoot a snow scene, the camera's metering system will not know whether it is snow or white, and will foolishly think that it is too bright here, so if the exposure compensation is 0, then the shot snow scene is a scene covered with "gray" snow. If we shoot a coal yard, the camera will foolishly think that it is too dark here. If the exposure compensation is 0, the photos taken are all "gray" coal. None of this is what we want. Therefore, when shooting the snow scene, it is necessary to appropriately increase the exposure compensation, so as to make the snow white; When shooting coal piles, we should reduce the exposure compensation and make the coal black. ▲ Appropriately increase exposure compensation. Snow is white. For beginners, it must be remembered that exposure compensation can't go wrong: exposure compensation has nothing to do with the brightness of the environment when shooting, but only with the brightness of the finished photo. Even if it is dark around, if exposure compensation is added, the final photo will be very bright; Even if the surrounding lights are bright, if the exposure is reduced, the final photo will be dim. From the above description, we know that exposure compensation is actually adjusted in some special scenes or special circumstances. For example, the object you shoot is bright and occupies a large area in the picture. In order to reflect the original brightness of the object, you should make the photo brighter and increase the exposure compensation. Similarly, if the object itself is dark and occupies a large area in the picture, in order to reflect the original color of the object, the photo will be darkened to reduce the exposure compensation. In addition, sometimes we want to explain that cheerful scenes will also improve the brightness of photos and increase exposure compensation. For some depressed and gloomy subjects, it is necessary to appropriately reduce the brightness of photos and reduce exposure compensation. ▲ In a sad scene, the brightness of many photos can reflect the photographer's shooting intention, so it can be said that exposure compensation is an important argument to reflect the photographer's shooting intention in photos. On our camera, as long as it is not a pure automatic camera, we can adjust the exposure compensation. If your camera only has automatic function, forget it. Generally, exposure compensation can only be adjusted in P (program exposure), A (aperture priority) and S (shutter priority) files. Although exposure compensation cannot be directly adjusted in M (manual shift), it can be controlled by adjusting aperture, shutter and sensitivity. ▲ Exposure compensation scale in camera shoulder screen. Exposure compensation usually appears in the form of scale or numerical value in cameras. Under the preset conditions, ......

How to adjust the exposure of SLR camera

Exposure is related to three values, aperture size, shutter speed and ISO. . You can change the exposure by adjusting any of these three. . . If you don't understand these three data, then you belong to SLR Xiaobai. Read the instructions first. . This is the most basic knowledge of trying SLR.

What is exposure? ! How to adjust? !

Exposure refers to the intensity of light and the length of time you feel. The brighter the object you want to shoot, the faster the shutter speed of the camera and the smaller the aperture. Aperture and speed should cooperate with each other. One adjustment may not take accurate photos. On the contrary, if the object you want to shoot is very dark, you must slow down and enlarge the aperture. Please contact me QQ752840536 for specific operation.
