How to set parameters

How to set parameters, the idea of parameter setting-

First of all, define the shooting theme:

In short, what do you want to shoot? What do you want to shoot, people or scenery? Darker or brighter? Before setting the parameters, you should be clear so that you can adjust the direction of the parameters.

Second, ask yourself to determine the parameters:

According to the shooting theme, ask yourself to determine the metering mode, shutter speed, light garden, ISO and other parameters.

I want to take a portrait at night.

Question 1: What about the ambient light? Is it backlight? (Determine the metering mode).

Question 2: Is the background of the characters messy and does it need to be blurred? What is the depth of field? (determine the aperture).

Question 3: Is the character in a static posture? Still a dynamic snapshot? What is your own safety shutter? (Determine the shutter speed).

Question 4: light pattern and shutter determination. Check the exposure meter to see if the exposure is correct. Dark or light? (Determine IS0).

The idea of parameter setting is just an example, not fixed.

Example 1-

① Portraits at night.

② Judging whether the light direction is smooth from the shadow can be used to evaluate photometry.

(3) There is traffic in the background environment, which affects the line of sight of photos. It is necessary to blur the background to highlight people and use a large light map.

(4) Static swing uses its own safe shutter speed at the current focal length.

⑤ Set ISO according to the exposure meter to ensure accurate exposure.

Example 1 parameter setting order:

① theme ② metering mode ③ light garden ④ shutter speed ⑤ISO

Example 2-

① Backlit portrait.

(2) judging the light direction from the shadow as the backlight, partial metering can be used.

(3) The background environment is clean, the sun's light intensity is covered by clouds, and it can be made into light with a small aperture.

(4) Use small aperture static swing and use your own safe shutter speed at the current focal length.

⑤ Set ISO according to the exposure meter to ensure accurate exposure.

Example 2 Parameter Setting Order:

ISO can be lowered to obtain high quality, such as S0- 100.

① theme ② metering mode ③ light garden ④ shutter speed ⑤ISO

Example 3-

① Children's photography.

② The light is soft on cloudy days, so the central composition can be measured by the central key average.

(3) In order to highlight people and avoid the messy green plants behind them, a large aperture is needed.

(4) Children are hyperactive and need a relatively high shutter speed to capture pictures.

When testing the shutter speed, remember to look at the focal length of the lens and consider the safe shutter reference value of the focal length.

⑤ Set ISO according to the exposure meter to ensure accurate exposure.

Example 3 Parameter Setting Order:

① theme ② metering mode ③ light garden ④ shutter speed ⑤ISO

Example 4-

① scenery photography.

(2) partial metering can be used in strong sunlight and backlight.

(3) The scene uses a small light map as usual to obtain a large depth of field, and the background is clean and there are no sundries that affect the aesthetic feeling.

④ Horses are out of control and need high-speed shutter capture.

⑤ Set IS0 according to the exposure meter to ensure accurate exposure.

Example 4 Parameter Setting Order:

① Theme ② Photometric Mode ③ Lighting Garden ④ Shutter speed ⑤ is 0.

Summary-

I personally recommend the sequence of parameter setting:

① Theme (what to shoot) ② Photometric mode (reference photometric mode) ③ Photogram (reference aperture) ④ Shutter speed (reference shutter speed) ⑤ Finally, set IS0 (reference sensitivity IS0 and exposure meter) against the exposure meter.

Parameters are dead, people are alive, and the theme changes with personal thoughts. There is no shortcut. Try every parameter, shoot more and practice more, and you will learn faster.
