Orpho Chrome Reversal color film, intended for daytime photography

Orwo chrome daylight film UT 21.

Size: Miniature 30ml films

36 photos.

Roll film, roll size 120

General characteristics: 1, great saturation LED film. After displaying, the transmission will be converted into positive transparent images that are suitable for projection directly, and are characterized by an infinite Sharpness (since no intermediate printing operations are required), and the power of determination (or the power of resolution (large resolution) in colors, even if the brightness of the different subjects included in the image differs. (This is in contrast to images printed on colored paper, which are not characterized by these characteristics), and the size of the graininess decreases to a large extent, and the tolerance of this film increases Latitude when compared to colored films, and this feature does not result in an increase in exposure slightly from the blame limit. Only slightly increase the intensity of the image without damaging the similar degree of color saturation

Arrangement of film layers:

(1) An upper layer that is sensitive to blue rays and bears yellow color problems.

(2) A layer of yellow filter

(3) A middle layer that is sensitive to green rays and bears scarlet color problems. (4) A bottom layer that is sensitive to infrared rays, and bears cyan color problems.

(e) A blue insensitive anti-halo layer. .

(6) Film support

(7) A colorless gelatin layer to resist curvature of the film after extrusion. (She is located in

Roll films).

The color temperature for which the film was prepared:

This film was prepared for filming during the day in rays with a color temperature of 5500 Kelvin, which is the usual color temperature in daylight in the summer, starting from two hours after sunrise until two hours before sunset. This campaign calls for the use of any optical filters even if a remote electronic flash is used, and the matter does not require an electronic flash either.
Sensitivity speed: DIN

Therefore, this film is considered one of the fast-sensitive reversal color films, which can record images of fast-moving objects with the possibility of narrowing the diaphragm apertures (to 8 f, for example). allow - as we know

. Previously, it was usual for colored reversal films to be known as Orwocolor reversal, then this name was changed to this film and became Orwo Chrom) to distinguish it from the previous name Orwo Color, because this new film (21 UT) requires a different display than what we knew about films or Refu Kauer, showing the new film requires only 87 minutes (without drying) if the temperature of the washing water is 514 C, while the old Orfo Chlor film required 160 minutes to finish showing it. Rather, the duration of showing the new Orwochrom film can be reduced by an amount (i.e. it becomes 44 minutes only) if we work to increase the temperature of the washing water to 524 C. Therefore, the hardness of the gelatinous layers of this new film has been increased to withstand the high temperature to this degree.

One of the advantages resulting from the possibility of reducing the exposure time is that the ability of the exposure solution to survive increases, and that it is capable of regeneration.

The first display solution is nothing more than a “black and white” display solution bearing the

As for the rest of the solutions for showing the film 21 Orwo Chrom UT, it also differs from what we are used to with regard to the old Orwo Chrom reversal films, and it is being shown in the factory laboratories (1) at the present time, and it is very likely that the factory will publish more information about it in the future.
