What is the info key on the SLR for?

The info button on the SLR is an information button, and its main function is to check the detailed parameters of the photo, such as aperture, shutter speed, AF area, metering, color space and other shooting information, so as to quickly understand the current camera settings.

Skills of using SLR

1, try to use the exposure setting of M file.

By using the manual exposure mode, you can set the shooting parameters of the camera well, whether it is shutter and aperture or ISO, and directly participate in the camera parameter setting, which can better control the exposure imaging of the picture.

2. Avoid using automatic white balance settings.

Although the automatic white balance function is relatively simple when shooting photos, it is not the case when shooting videos. Because there will be many environmental changes when shooting short films, the use of automatic white balance will directly lead to different colors of several video pictures, which will make the pictures very different.

3. Use a high-speed memory card.

The shooting of high-definition short films requires high reading and writing of camera memory cards. The memory card with excellent performance can quickly record high-definition short films, prevent frame loss, avoid the failure of the camera or memory card, and avoid unnecessary troubles.
