Steps to obtain the underlying image:

In order to obtain the latent image, we need steps that we briefly describe as follows:

a) Adjust the distance between the lens and the sensitive layer to suit the distance between the object
and the lens.

b) Determining the amount of light that is allowed to pass through the lens to form the latent image. This last step is called the exposure process. The exposure process can be defined as allowing the amount of light required to form the latent image on a unit area in the sensitive layer in a unit of time. The exposure factors, then, are the intensity of the light, and the time the light passes, and the relationship between them is determined as follows:

Exposure = light intensity x time

v = k x g

The optical camera is the means by which it can control the intensity of light and the time of passage of light. Through the aperture of the Dia Fragm, we control the intensity of the light, and through the Creator, we control the time of the passage of the light, and since the time of the passage of the light is directly related to an important factor in photography, the speed of movement of the object that will be photographed, we can summarize the steps that must be prepared to obtain the latent image in:

A) adjusting the distance between the lens and the sensitive layer to suit the distance between the body and the lens.

b) Estimating the appropriate shutter speed for the body's movement speed and its distance from the lens.
