Exposure compensation order
For the operation of white balance I think that you should use Kelvin.
Approximate television width is determined by numerical values from 10,000 to 2500, the higher the warmer the color, the cooler the color the lower the lower the color.
First, set the aperture value.
Next, adjust the ISO sensitivity.
Finally, decide the shutter speed.
To blur the background and make the subject stand out, it’s important to have a blur, so it is important to lower the aperture value.
I think that ISO sensitivity may be set to 100 if it is taken in a bright place.
When photographing stars in the night sky, the sensitivity value may be just as good as 800 to 1000.
Basically do not change the aperture value and ISO sensitivity.
