How to adjust the Mx3 camera?

1. Exposure compensation

How to open: click six times on the three dots in the lower right corner of the camera interface.

In a well-lit shooting environment, such as outdoors, use the default mode of the mobile phone camera to take photos. The photos taken in this way will generally be overexposed or whitened. If you take pictures of petals, The petal texture is basically invisible.

Solution:

Reduce the exposure compensation to 4 stops, which can be reduced by 1-2 stops. This depends on the actual situation and the effect after reducing the exposure compensation.

2. ISO - sensitivity

ISO values ??are 50, 100, 200, 400, 800. ISO50 and ISO100 are used in sufficient light conditions, while high ISO200-800 values Use in low light situations.

Generally speaking, the lower the ISO value, the higher the quality of the photo and the more delicate the details of the photo. The higher the ISO value, the brighter the photo, and the quality of the photo will decrease as the ISO value increases, and the noise will become more and more serious, but the high ISO value can make up for the lack of light.

Under special circumstances, if the ISO value is set high, the photos taken will appear wavy. The solution is to lower the ISO.

In addition, the level of ISO also determines the exposure value. The exposure value is a numerical value that represents the amount of light passing through the photographic lens by combining the shutter speed value and the aperture value. The lower the shutter speed, the larger the aperture, the larger the light time and area, that is, the smaller the exposure value.

The lower the ISO, the longer the exposure time required, and the better the anti-shake technology is to achieve a good shot. Lower ISO is generally used for photographing static objects. For example, macro photography of flowers.

The higher the ISO, the shorter the exposure time required. This anti-shake technology is not so good. It is generally used to take pictures of moving objects. For example, if you take pictures of the window in the car at a speed of 200KM per hour, scenery.

As shown in the two pictures below:

ISO-50 exposure time: 1/7 second ISO-800 exposure time: 1/106 second

Of course this It's not absolute. There are many other factors involved. ISO-50 is not necessarily slower than ISO-800. There are also ISO-50 exposure times: 1/1000 seconds, etc. Generally speaking, if the interface is enlarged to the maximum for macro photography, the exposure time may range from hundreds to thousands. But when taking photos at night, it may be ISO-800 1/2 second, which takes half a second to image.

When the camera is set to automatic by default: ISO-100, in macro mode: ISO-50. I don't know about the others without trying them.
