How to adjust the exposure of SLR camera?

SLR players enter. How to set exposure?

The instructions are very clear. Then I'll briefly talk about it here. Generally, playing SLR is M-file, that is, full manual. Including self-adjusting aperture, shutter, sensitivity, white balance and so on. File A is an aperture priority file, also called aperture priority file, which means to manually adjust the aperture, and other items are automatically processed with the value of your exposure meter. If you open the aperture to the maximum, that is, the maximum amount of light, the corresponding shutter speed will also increase accordingly. I suggest you use M files more, read the instruction manual and some photography books.

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.

Exposure compensation of SLR camera

Is exposure compensation only useful in A /S /P files?

Answer: Yes.

That is to say, in the M file. . . Is it chicken ribs?

Answer: This is a mistake. Exposure compensation is only designed for automatic (P mode) and semi-automatic (A mode, some cameras are in S mode /T mode), not for M file.

When it comes to exposure compensation, we have to mention the metering mode of the camera. At present, the commonly used electronic metering mode is based on 18% gray scale. Whether it is P, M or A/S files, the camera will regard the subject as gray, and then give a reference standard. So under the automatic function, the white object is dark and the black object is white.

In order to reflect the real color more accurately, or express some special feelings of photographers, it is necessary to adjust the exposure to increase or decrease. In manual mode, you can increase or decrease the light according to your own wishes, and "exposure compensation" is realized through the human brain; In automatic or semi-automatic mode, it can only be realized by the "exposure compensation" function of the camera.

Film age, and exposure compensation. How to increase or decrease is experience.

Just increase the aperture or shutter by one step, and the amount of light will double. For example, F/8,1125 has a fixed light quantity twice that of F/8, 1/250. If you reduce one gear, you will reduce it by half.

At the same time, increase one gear and get 4 times exposure.

Canon EOS SLR camera, manual mode, in the sun, how to adjust the exposure so that the photos are not all white?

You're overexposed.

I'll teach you a simple method. First, you can switch to the automatic position and shoot in the same position. You can look at the parameters at this time when focusing, and then you can shoot with the same parameters in manual mode.

Of course, in this case, if there is a big difference between light and dark in the framing range, the bright place is estimated to be overexposed.

Actually, it's enough to shoot with AV files. In too bright environment, adjust the aperture to about 8 and the camera program will automatically set other parameters. Set the metering mode to spot metering, and then shoot after metering the parts with moderate brightness in the whole range.

How to set the "exposure time and aperture" of SLR camera to achieve the best effect?

There are no absolute settings for exposure time and aperture. According to the scene and requirements, the compensation function can also be used in subtle places. Beginners should not be too complicated and should not use manual gear. This is not asking for trouble. You have to compose a composition, set the aperture, shutter and exposure compensation, and think about what effect this setting should have. It is best to set an aperture priority (large aperture, small depth of field, small aperture and large depth of field) or shutter priority or P file (program offset is also acceptable).

How to set the second exposure of SLR camera

For automatic film SLR and digital SLR, this requires the camera to have the function of repeated exposure, otherwise only PS synthesis can be used. For manual film SLR, you can press and hold the rewind key and move the film wrench again.

How to adjust the exposure coordinates displayed in the SLR viewfinder?

Looking at the exposure ratio alone, the offset from left to right is much more compensated. Only by reducing compensation can the normal exposure level be restored. The coordinates displayed by half pressing the shutter to the right and left remind us that we should adjust the exposure compensation to get the correct exposure. The indication of exposure scale is the appropriate combination of aperture, shutter and sensitivity. For example, the normal exposure value required for a certain scene is F4, 1/80S and ISO 100. Suppose you set the full manual shift, the camera aperture is set to F2, and the sensitivity is set to ISO 100. At this time, the shutter speed is not enough, and the exposure scale will show higher than the actual exposure value. At this time, it is necessary to manually increase the shutter speed to ensure the correct exposure. The camera can judge the situation by itself and change the exposure combination to achieve the correct exposure when shooting in other semi-automatic/full-automatic gears such as S, A and P.. To give another typical example, suppose that the exposure value required in the scene is ISO 800, 1/30S and F2.8, and this exposure value can be roughly equivalent to F2, 1/40S and ISO 800, or equivalent to F2.8 and 65438. Now you can understand.

How to control the exposure of SLR camera

If you are used to taking pictures manually, you must be familiar with the exposure parameters. It is determined by three factors: aperture, shutter and sensitivity. Generally, cameras will give instructions on safe exposure.

How to adjust the underexposure when taking pictures with SLR camera?

First, add exposure compensation (for AUTO, P, A and S files).

Second, reduce the shutter speed (applicable to M and S files)

Third, increase the aperture value (applicable to M and A files)

Fourth, improve ISO (applicable to M-file) on the premise of keeping the aperture shutter unchanged.

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 is always an important parameter in the camera to remind us, that 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 advanced 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 sad scenes, the brightness of many photos can reflect the photographer's shooting intention, so it can be said that exposure compensation is an important parameter 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. General exposure compensation can only be adjusted in P (program exposure), A (aperture priority) and S (shutter priority). 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. Absence ... >>
