How to use M file of Canon camera?

1 and m files are both manual files, with the advantage of accurate exposure and the disadvantage of slow parameter adjustment;

2. According to the different shooting subjects, there are generally three elements that must be mastered. One is the control of depth of field, such as taking portraits and still life; The second is speed control, such as shooting fast-moving scenes; The third is to control the sensitivity (ISO), and low sensitivity can be used instead of high sensitivity;

3. When using M file, pay attention to the exposure scale below the viewfinder. The cursor of the exposure scale is usually exposed in the middle (scale is 0). The exposure ruler cursor is dark when exposed to the left (left exposure), usually used for landscape shooting, and bright when exposed to the right (right exposure), usually used for portraits, which will produce different imaging styles;

4. When using M file, you can first determine the sensitivity and aperture or speed according to the subject. For example, taking a portrait as an example, you can choose to determine the sensitivity and aperture, fix these two parameters first, then visually observe the exposure ruler in the viewfinder, and continuously adjust the shutter speed with the pulsator until the cursor of the exposure ruler stays in the center (0 scale), and then press the shutter. If shooting extreme scenes, you should adjust the shutter speed first, and then adjust the aperture or sensitivity. When the cursor of the exposure scale stays at the center (0 scale), the exposure is accurate.

5. The basis of using M file is to adjust the shutter or aperture, so that the cursor of the exposure ruler is centered, and you can take a film with accurate exposure. As for the imaging style, it can be changed on the basis of accurate exposure;

6. For beginners of M grade, you can practice at home first. After determining the subject, first determine the aperture, such as F5.6, and then determine the sensitivity. For example, the maximum ISO of automatic sensitivity cannot exceed 1600. After these two items are confirmed, turn the shutter dial toward the viewfinder until the cursor of the exposure scale is centered. Practice makes perfect. Use M file in the future.

7. The method of fast learning is to focus with P file first, then remember the aperture, shutter and sensitivity values automatically generated by the camera in P file, and then use M file. According to the above method, you can find the closing shutter value, which is faster.
