Part 1: Why Is It That Old Films Always Appear Blurry?

There are numerous reasons for the unclear quality of old films, including technical constraints, preservation conditions, and human factors:

Technical Limitations

Shot Technique: Early photography techniques were relatively primitive, employing films with lower sensitivity, resulting in a greater amount of noise and insufficient clarity in the images. Furthermore, the 16mm or smaller film gauge used in early cinema production, with its inherently lower resolution compared to modern 35mm film, contributed to a less visually appealing image quality.

Post-processing Techniques: Older photographs and film negatives may suffer from reduced image quality due to incomplete processes during the developing process. For instance, the magnifier's precision was inadequate, preventing precise alignment of the film and paper, leading to blurred edges on the photographs.

Storage

Physical Wear and Tear: As time goes by, the film will gradually age, and scratches, mildew and other problems will appear, which will lead to a decline in image quality.

Storage Conditions: Improper storage conditions, such as high humidity and large temperature changes, will also accelerate the degradation of the film and affect the image quality.

Human Factor

Shooting Level: The shooting level and experience of the early film production team were limited, which may lead to problems in picture composition, focus, etc., thus affecting the picture quality.

Personal Preference: In the post-processing process, early film production teams may deliberately increase noise and blur edges for artistic effects or personal preferences, which reduces the quality of the film.
