Three elements of exposure

hole

An aperture device that controls light to enter the camera. The aperture size is expressed by f value.

The smaller the f value, the larger the aperture, the more light entering, the brighter the picture and the deeper the depth of field (blur).

The larger the value of f, the smaller the aperture and the less light entering. The darker the picture, the shallower the depth of field.

shutter

A device that controls the time when light enters the camera. Shutter speed is expressed as1/x.

The smaller the shutter value, the faster the speed and the darker the picture, which is suitable for capturing wonderful moments.

The larger the shutter value, the slower the speed and the brighter the picture, which is suitable for shooting motion trajectories.

International Organization for Standardization (ISO)

Sensitivity refers to the sensitivity of camera photosensitive elements to light.

The larger the ISO value, the higher the sensitivity to light, the brighter the picture and the more noise.

The smaller the ISO value, the lower the sensitivity to light, the darker the picture and the less noise.

Camera shooting mode

B B door

Press and hold the shutter button/Bluetooth remote control, etc. The camera is kept on, which can achieve long exposure and is suitable for shooting star tracks and fireworks.

Manual exposure

Manually set the aperture, shutter speed and ISO, which is suitable for photographers who know the parameter settings very well.

automatic programming

The camera automatically adjusts the shutter speed and aperture, which is suitable for beginners.

AV aperture priority

Manually control the aperture and automatically adjust the shutter, suitable for shooting portraits, still life and other scenes.

A+ intelligent automatic

The camera automatically adjusts the shutter speed, aperture and ISO, and intelligently recognizes the scene, which is suitable for beginners.

Television shutter priority

Manually control the camera shutter speed and automatically adjust the aperture.

Shoot fast moving objects or want to shoot with slow doors.

measure

Evaluation photometry

After dividing the whole area into multiple areas, measure the light in each area to determine the exposure of the whole picture.

Suitable for scenes with little contrast between light and shade.

Partial measurement

The camera will automatically adjust the shutter speed and aperture. Suitable for beginners.

Spot photometry

Canon's unique metering method is often considered as a branch of spot metering, and its metering range is slightly larger than spot metering. Suitable for stage/portrait, etc

Central photometry

When measuring light, it will be biased towards the center of the picture, taking into account the edge of the picture.

Suitable for shooting scenes with the subject in the center of the picture, such as portraits/buildings/still life/macro, etc.

Focus mode

AF-S single autofocus

Single autofocus is often used to shoot still people or scenes.

Not suitable for shooting dynamic subjects.

AF-C continuous autofocus

The focusing system can constantly adjust the focal length of the lens according to the movement of the focal point, so that the shot picture is clear and bright.

If the camera performance is poor, it is easy to lose focus.

Auto-focus-Intelligent Auto-focus

The camera can identify whether the picture is still or moving, thus automatically selecting the mode of single focus or continuous focus.

In the process of shooting, the focus is often not ideal, so it is necessary to manually switch the focus mode.

intermediate frequency

Manual focus

Manually change the zoom ring to focus. Suitable for macro shooting, or scenes with dense obstacles between the camera and the subject.

MDF full-time manual focusing

After focusing with autofocus, you can manually fine-tune the focus.

Suitable for macro shooting.

Light classification

natural light

It's the light of the sun. The color temperature of the light at sunrise and sunset is very low, and the light is warm and soft. Because the light intensity is low, it is the best time to shoot the sun.

Scene lamp

Indoor light basically belongs to scene light. Including sunlight in the window, indoor lights, and light from some luminous objects. Characteristics of scene light: complex light source and weak intensity.

artificial light

Artificial light An artificial light source set by a photographer to achieve his creative intention. There are mainly two kinds of artificial light sources, one is that the continuous light source is always visible, and the other is that the flash is short and needs to be foreseen.

Mixed light

Mixed light refers to the combination of two or three light types mentioned above, so as to better illuminate the subject or depict the artistic conception of the picture.
