How to Adjust the Histogram of Digital Camera

Have you ever seen wedding photos or artistic photos? Because of the hazy background, the hero and heroine are more beautiful and feel like angels. Such photos with clear theme and blurred background seem to be carved by image processing software or by famous artists with profound skills. Actually, they are not. It can also be done with a digital camera!

In the scenic spot, if you don't want to catch the garbage behind you into the picture, you can use a large aperture to remove the complex background. If you want to take special effects photos, you must learn the aperture setting!

At present, almost all digital cameras with manual adjustment mode on the market have aperture settings. Next, we will take Nikon as an example.

As a demonstration, e990 sets the so-called "aperture" and uses "aperture priority" to let the digital camera measure the light to determine the shutter speed. If the digital camera in your hand is different from the model we introduced, you can refer to the instruction manual to operate it together.

1

First, adjust the mode of the digital camera to "manual mode".

2

Then adjust to "Aperture Priority".

three

Turn the knob to adjust the aperture value.

four

Then face the subject, half press the shutter to focus and measure light.

five

On the lcd of digital camera, the shutter value after metering will be displayed.

Note: If the shutter value after metering is too slow, it is recommended to fix the digital camera with a tripod before taking pictures to avoid the phenomenon of blurred photos.

Setting the aperture of a digital camera is as simple as that. Next, use Nikon.

E990 sets various aperture values, and takes photos of beautiful women after metering with the camera shutter speed. You can also try to see how to take pictures in order to take enviable photos.

By carefully comparing the photos on the right, I believe we can clearly see the relationship between the change of aperture and the change of background. Come and try it!

Aperture 2.8 and shutter 1/400 use different apertures. Why is the shutter speed different?

This is a matter of exposure. Suppose a glass of water is full, which means the exposure of this photo is just right. If it is less than a glass of water, it means that it is underexposed and the photo will be dim. The spout represents the aperture and the pouring time represents the shutter speed. Figure 1 has a small aperture, and you can get enough exposure after two seconds of exposure. The aperture in Figure 2 is large, and you can get the same exposure in just one second. So we can know that different apertures will cause different shutter speeds.

What exactly is an aperture? What are the advantages of digital cameras in this respect?

Aperture is the movable blade in the lens. By controlling the aperture, the camera can decide how much light will enter the film room or the ccd photosensitive element of the digital camera in the same unit time, which is one of the principles of photography. As long as the size combination of "aperture" and "shutter" is controlled and adjusted, the exposure of photos can be changed. The quality of a photo is often determined by the exposure. Underexposure or overexposure will affect the imaging of photos, and then they will be too bright or too dark.

In fact, the value of aperture also directly affects the depth of field of the whole photo. If the aperture is large, the exposure time can be shorter, which can not only cause the special effect of the depth of the scene, but also take pictures without flash when the light is bad.

The advantage of a digital camera is that it can be adjusted to the appropriate aperture value immediately and take photos that are more in line with your own needs.

Take more pictures with a digital camera, and you will find that the same lens, different aperture and depth of field will change greatly.
