Main points of SLR shooting

The bigger the aperture, the brighter it is.

The slower the shutter is, the brighter it is.

The higher the sensitivity, the brighter.

Ambient light, aperture, shutter, sensitivity

The stronger the ambient light, the brighter it is.

Other same as above.

Power, distance, aperture, sensitivity, focal length

The greater the flash power, the brighter it will be.

The closer the flash is, the brighter it will be.

The bigger the aperture, the brighter it is.

The higher the sensitivity, the brighter.

The longer the focal length, the brighter.

Aperture, focal length and focusing distance

The larger the aperture, the shallower the depth of field.

The longer the focal length, the shallower the depth of field.

The closer the focal length, the shallower the depth of field.

Far background, close lens, large aperture, long focal length.

Intensity, direction, color temperature

Intensity is whether it is bright or not.

Where does the direction come from?

What is the color temperature?

Natural light, scene light, artificial light

Natural light is generally the light source of the sun.

Jingguang is often the other indoor light source.

Artificial light is the ever-burning lamp or flash in the studio.

Tone, purity and brightness

What color is hue?

Purity is saturation.

Brightness is the brightness of light.

Reduced clarity, loss of details, increased noise, and color shift.

The loss of sharpness and detail makes the photo unclear-it appears first.

The increase of noise makes the picture dirty-but this is the least important.

Color cast means that there are a lot of dirty color blocks, and the hue of the color changes-it is very bad.

Inaccurate focusing

Relative displacement between camera and main body

The mechanical or electronic problem itself.

GN index, maximum flash synchronization speed and synchronization mode

The GN index represents the power of the flash, which is equal to the aperture multiplied by the distance.

The highest flash synchronization speed indicates the fastest shutter speed at full power output.

Synchronization mode includes high-speed synchronous flash and slow flash, and slow flash includes front curtain synchronization and Hou Lian synchronization.

Focal length, maximum aperture, nearest focal length, magnification

The focal length indicates the framing size and variable range.

The maximum aperture indicates the light transmission ability of different focal lengths.

The nearest focal length means, er, the nearest focal length.

The magnification indicates how large an object can be placed on the sensor.
