What is a reversal film camera? What are the characteristics of reversal film?

Reversal film is the photosensitive material used in traditional photosensitive cameras. Simply put, it is what we usually call film.

SLR - is a type of photographic equipment, the full name is single-lens reflex camera. It can use lenses with different focal lengths and purposes. The eyepiece and objective lens are used to capture and image the image through the same lens.

Reversal films are also called slides. Generally speaking, reversal films have better color saturation, high contrast, and most importantly, good detail levels. For example, the response to dark parts is very good. Negative films generally don't respond as well to dark areas as reversal films. Generally speaking, reversal films cannot be processed in ordinary processing shops and must be processed in professional shops. The general processing process is E-6. Therefore, there is not much difference in flushing effect. Another way to use reversal film is to negative process reversal film. And the reversal film is developed using the negative film processing process (usually C-41), which can achieve a tone separation, high saturation, and high contrast effect. The effects of various reversal films after negative processing are different.

The photos obtained by negative processing of reversal films have bright colors and high contrast, and the red, blue, and yellow colors of the scenery are particularly exaggerated; objectively speaking, negative processing of reversal films has better color than negative films. It is more expressive in terms of expression, and the exaggerated expression of its tones is inferior to that of color negative film. However, in terms of gradation expression, reverse negative processing is inferior to negative negative processing, so it is very important to first establish the subject and then choose the film type. Inverse negative processing is mainly suitable for portrait photography and some landscape photos. Under the negative processing of reversal film, these two shooting subjects have strong contrast, prominent subjects and bright colors, giving the photos a unique charm.
