What's the difference between color film positive and negative? What kind is common in the market?

Generally, negatives are sold in the outside market.

1, different definitions

Color negative, after being developed, the color on the negative (negative) is the complementary color negative of the original color. Color reverse film, that is, positive film, can obtain the same color positive image as the subject through the reverse development process.

Step 2: Different colors

Color negative film is affected by color temperature and surrounding environment when shooting, which will cause color deviation of negative film, but different filters can be used to correct it in photo production. Color reversal film, its color is true, bright and full.

3. Different sensitivities

The sensitivity of color negative film is much smaller than that of black and white film. Color reversal film requires strict shooting, low sensitivity and accurate exposure. If the exposure difference is 1/2 times, various colors, densities and layers will be obviously affected.

Advantages of reversal film

1, for beginners, because the reverse film is a positive effect picture, it is more suitable. In other words, the effect of your shooting is the same as what you see. The negative needs the photographer to consider the printing effect of the picture. The reverse film truly reflects the image effect on the negative film.

2. Reversing the film is beneficial to scanning. Looking back on a particular scene two or three years later, I may not remember it, at least I can't remember it. If the accuracy of color is very high, it's best to scan with reverse film, because reverse film has more advantages than negative film in color accuracy.

3. The color saturation and contrast of the reversal film are relatively high, which makes the picture more realistic and is especially useful for low contrast scenes.

4. For most people, the reverse film is easier to save and takes up less space.

Most publications use reverse films, and rarely consider publishing with negative films. Although sometimes digital or scanning can be used, it is actually the conversion from negative film to reverse film.
