but I would like you to understand
Thank you
In this issue.
I will write about shutter speed.

Shutter speed is
The shutter speed is the speed between the opening and
closing of the shutter.
By changing the speed, the light entering the
film is adjusted.

Turn the shutter release dial to change the speed.
With this camera
X (orange), B , and numbers from 1 to 1000 are marked.
First, the speed of the numbers 1 to 1000,
1 is 1/1 second (1 second)
60 is 1/60 second (0.6 second)
1000 represents 1/1000 of a second (0.001 seconds)
The higher the number, the faster the speed.

This is before the shutter is released.

The shutter is so super fast that you can only see half of it.
This reduces the amount of light.

I’m talking about the non-numeric characters on the shutter dial.
“X” (orange) is the speed position when shooting with a strobe
“B” is called bulb, which means that the shutter opens while the shutter release button is pressed.
When the shutter release button is released, the shutter closes.
Therefore, the amount of light can be determined by the
shutter release button.
And shutter speed is related to aperture.
There is a separate column on aperture.
Please see there.
Adjust the amount of light from the lens.
While adjusting the aperture
Further adjust the shutter speed to send the appropriate amount
of light to the film.
These are some of the things we have written about
ISO sensitivity.
I will write about “exposure” in the next issue.
