There is only one principle we should follow for the range of framing: we can make your theme clear, highlight your theme and simplify your picture. If it helps to express the theme, stay; If it does not help to express the theme, remove it; Adopt a framing method that helps to express the theme; A way of framing that doesn't help express the theme, no.

Cutting is the best simplification method. Remember, photography is subtraction

Whether the second picture is a good way to highlight the key points, but it is not that the smaller the framing range, the better. It depends on the actual situation. If the close-up has a lot of sundries or affects the main body, it will be reduced.

How to shoot a melon face when taking a selfie? The biggest theme of a good selfie is to make yourself beautiful. If the shooting angle is reversed, the girl's chin will be closer to the camera, and it will become a melon face. If the camera is shot from above, the girl's chin will be far away from the camera and turn into a melon face.

Second, the tone

00 1. Definition: Tone refers to the brightness of photos. Bright photos are high-key, dark photos are low-key, and those that are not bright or dark are medium-key.

002. 18% ash is also called 18 degree ash, which is neutral ash. Extremely white and extremely black are located at the two ends of the spectrum, and the gray between them actually reflects 18% of the incident light. Therefore, we simply call 18% grey neutral grey, which means intermediate tone.

003. Most photos are in the middle tone, and a few scenes need to be high-key or low-key. Then I remembered the neutral gray of ps, hahahaha!

Third, tone quantization.

00 1. The orange box in the above picture is the exposure compensation scale, indicating that the exposure given by the camera is in the middle tone. If what you shoot is bright, you will be compensated. Your film is darker, make it up. The middle key is not compensated.

002. Intermediate tone = 18% gray = =0EV. +1ev when the brightness of the photo is increased to twice the gray level of 18%; If the brightness of 18% gray is dimmed to 1/2, it is-1EV. The brightness difference of each EV is twice.

003. The most intelligent cameras often adopt segmented area metering mode. Generally, the picture is divided into many areas, and then the exposure of each area and its importance in the picture are judged. Finally, the normal exposure is obtained by weighting.

004. Center key average photometry

It is to focus on the exposure of the central subject, and then weight the exposure of other backgrounds.

005. Spot metering is to measure a point in the picture.

This point is generally very small, and the area in the figure is 1% ~ 3%. The more advanced the camera, the smaller the metering area.

Because the skin color of the yellow race is close to 18% gray, it will be normal to measure the face. When the exposure compensation shows 0, it is normal exposure of 18% gray scale. Black people are not like this.
