aiming

Many beginners think that aiming a camera is like aiming a gun, all they have to do is place the subject to be photographed in the center of the viewfinder and press the trigger.

Contrary to this logic, the expert photographer knows that aiming is the most important thing in the photographing process, because he knows that as soon as the camera trigger is pressed, the matter is finished and he has no control over the matter of the image except the least. that it

Therefore, the photographer analyzes the scene that he sees through the viewfinder, element by element, and then as a whole. For example, he examines the foreground of the image and its relationship to the subject, as well as the background of the image. It examines the lighting, the distribution of light and shadows, the perspective, the possibility of distortion of the scene, etc.. etc.. which we will discuss in the third chapter. In short, the correction process requires three things.

1- To explore the scene through the viewfinder and study it and its defects. 2- To isolate the part to be photographed. - To organize the scene to give the required artistic composition

After his heart was completely satisfied, he pulled the trigger. We will return to this in detail in Chapter Three
Something remains in the correction process, which is the relationship between what the photographer sees through a specific point

Parallax and what the film sees through the lens.

The viewfinder of a single-lens reflex camera (AWD) sees about 90 to 98% of what the film will capture. Therefore, make all the components of the image within the frame of the viewfinder, because during the automatic enlargement, only about 85% is printed. The image recorded on the film. If there is an important part of the image, do not let it come too close to the edges of the viewfinder frame

The difference between what the eye sees and what the film sees in a single-lens reflex camera
As for the viewfinder in cameras with a viewfinder independent of the lens (mm) range-finder, you will find that there is a bright frame and this frame contains about 85% of the image that will be recorded by the negative. Shooting at a close distance of less than one and a half meters, as there is a difference between what the lens of this type of camera sees and what the viewfinder sees. and becomes. This difference is very noticeable at close distances.

Viewfinder for cameras with viewfinders

With regard to dual-lens reflex cameras, the same thing happens due to the difference in view between the vision lens and the image capture lens. But in this case, the image is shortened from above when photographed from close up. . It is noted that the viewfinder in different cameras contains various information such as shutter speed, pupil aperture, red and green lights, or + signs, - to know the exact exposure, so use the camera manual for your camera.
