Excuse me, Nikon photographer. . What are the functions of ADL, BKT and HDR in Nikon SLR? What do you mean?

1, ADL: active d-lighting, generally used in high contrast environment, only needs to shoot once, which can make some originally dull and bright details more obvious and basically restore the visual intuition of human eyes, but the photos taken are generally gloomy and noisy.

2.BKT: brackets, meaning "surrounding". Now many SLR cameras are generally equipped with surround function. Simply put, bracketing exposure is to form three photos with different exposures after one shot.

When we are not sure whether the current exposure is accurate or not, we use the enclosed exposure function (press the shutter three times or use the continuous shooting function) to take photos with three different exposure results: increased exposure, normal exposure and reduced exposure, and then choose the more satisfactory photos.

3.HDR: High dynamic range, generally by taking multiple photos (under-exposure, over-exposure and normal exposure) in succession. The human eye is not intuitive, the overall imaging is bright and the visual impact is strong, so jpg is the only imaging method.

Extended data:

First, the scene suitable for using HDR:

1. In landscape photos, there is usually a huge contrast between the sky and the land. If your camera takes pictures, it is difficult to deal with this contrast. With HDR, you can capture the details of the sky without making the ground or horizon look dark.

2. People in the sun. As we all know, light is very important for a good photo. Too strong light will cause disharmonious effects such as shadows and glare on people's faces. HDR can eliminate all discordant factors and make your shooting theme look better.

3. Low light and backlight scenes. If your photo looks a little dark, this often happens. If there is too much backlight in the foreground of your photo, HDR can brighten the foreground without diluting the right part of the photo.

Second, scenes that are not suitable for HDR:

1, shooting moving objects. If your subject is moving and HDR effect is turned on, the photo is likely to become blurred.

2. High contrast scenes. A photo will look better because the bright and dark parts are in sharp contrast. Turning on HDR will reduce this contrast and make the photo unattractive.

3. Colorful scenes. If you want to shoot the color of the scene, it is very vivid. It is not recommended to turn on HDR at this time, which will make the color much lighter.
