How to use manual mode for Canon SLR camera?

The use of full manual mode of SLR camera;

The full manual mode is called M for short, and the full automatic mode is just an extreme. In automatic mode, all parameters are set by the camera, and the photographer can't even change them. Manual mode means that the photographer has full authority to set the aperture value and shutter speed of the camera. In this mode, the photographer can set the aperture value and shutter speed completely according to his own shooting intention, so that the shot image is consistent with the image he wants, which is suitable for friends with special creativity and ideas.

Many such combinations are stored in the camera's automatic exposure program. When shooting, the camera will automatically select the exposure combination to get the correct exposure. However, in an environment with complicated lighting, such as a hotel on the street; There is also a very dark environment, such as the alley at night. The light metering system of the camera can't identify the light intensity at all, and can't choose the correct exposure combination. At this time, it is very useful to set the exposure parameters manually. You can get the correct exposure by constantly changing the exposure combination.

The actual situation is very complicated. Because the aperture and shutter are combined, for example, the aperture is F 1 1, the shutter is125 seconds, the aperture is F8, and the shutter is 1/250 seconds. The photographer will get some special effects by changing the aperture size and shutter speed, such as increasing. Even deliberately overexposed to increase the whiteness of the face and underexposed to highlight the three-dimensional sense of dark objects. These are all things that camera automatic exposure can't accomplish.

There are more complicated things, such as shooting fireworks, opening the shutter and waiting for the fireworks to appear, shooting portraits at night, and keeping the shutter open after the flash lighting to get the correct exposure of the background. These are also jobs that automatic exposure can't complete or can't complete correctly. Therefore, for people who study photography, it is necessary to fully expose manually. Automatic exposure is only suitable for recording life with a camera, and knowing how to use and skillfully use the full manual mode is the beginning of real photography.

How to use full manual mode:

1. Using aperture priority mode, the shutter speed parameters are obtained by spot metering and provided to M mode for reference in parameter setting.

2. Adjust the camera mode to M mode, set the aperture value and shutter value, and check whether the cursor position of the camera's built-in exposure meter is near 0. ?

Third, when shooting, it can be corrected by the cursor display on the built-in light meter in the camera viewfinder. The built-in exposure meter is the horizontal axis, which goes from negative value to positive value after 0. A negative value of "-"indicates underexposure; "0" means normal exposure; A positive value of "+"indicates overexposure.

Fourth, the cursor that does not need exposure compensation can be reset to 0. For a large area of white or black subjects, compensation should be made for white plus black minus. Canon camera's M file can't compensate for exposure like AV file. You can be flexible. When "white plus" is needed, the cursor is biased to "+"; When "black subtraction" is needed, the cursor is biased to "-"to achieve the purpose and effect of exposure compensation. Go shoot it.

5. After the shooting is completed, combine the histogram and playback effect, and then modify the determined parameters to start the formal shooting. M mode can be used for direct composition and focus shooting without metering. Because the light and shooting angle will always change under complex lighting conditions, you can always pay attention to the position change of the cursor of the exposure meter and make corrections as needed.

In addition, there are three ways to view the built-in exposure meter:

In the optical viewfinder.

2. On the shoulder screen (advanced and intermediate machines).

3. On the LCD that shows the shooting in real time.

1 and 2 models are suitable for viewing and correcting parameters during optical framing shooting. The third type is suitable for real-time display, viewing and modifying parameters during shooting.

The advantage of manual mode is that photographers can control their exposure conditions to express their photographic works, thus producing visual effects of overexposure or underexposure. In the case of complex light, large light ratio and strong backlight, it can also shoot beautiful blockbusters like professional photographers and give full play to the performance of SLR cameras. Let more photographers enter the ranks of SLR. Let more photographers with SLR cameras easily master full manual shooting and enjoy the happiness of photography calmly and confidently.
