LUCKY COLOR FILM SUPER GBR 400

LUCKY COLOR FILM SUPER GBR400

Lucky Super GBR 400 high-speed color film is the latest product developed by China Lucky Film Corporation, which is of the same series of Lucky Super GBR100 color film.
It has some good characteristics on granularity, definition, color reproduction, exposure latitude ,latent image stability and physics.
It is designed for photography with poor natural light indoors and outdoors and for photography on moving objects.

SENSITIVE PROPERTIES

--Sensitivity

The speed marked on film is ISO400/27°.It has good straight line, therefore, the image tone reproduction of dark part is improved and the image tone of hightlight part has good reproduction as well. When the temperature of shooting light source is 5,500K, cruve of sensitive properties is as Diagram1.

--Contrast

Lucky Super GBR400 color film has a suitable contrast so as keep a suitable contrast of distant scenery and avoid making too hard contrast of convenient scenery and keep the general moderate contrast of image.

--Exposure Latitude

Adopting the multi-layer in both red, green and blue sensitive layers in Super GBR400, the three sensitive curves have good straight line, which makes the exposure latitude wider from -1.0EV to +3EV.

--Interlayer Effect

Due to the adoption of new DIR coupler, DIR compounds and DIAR coupler, Super GBR400 obtains strong interlayer effect. The single color contrast is improved and the color saturation is strengthened, therefore, the image of Supe GBR400 becomes sharp, bright and saturated.

--Spectrum Characteristics

The Spectrum sensitivity curve of Super GBR400 shown in Diagram 2 has cut off in the UV part which makes the image not cyan when the illumination exists lot of UV rays or the objects have strong reflection in UV part.
Meanwhile, the blue-sensitive layer is sensitized spectrally and the blue sensitive and blue sensitive peak becomes obvious. The red sensitive and green sensitive layers have a sensitized peak respectively and the film records the color of objects realistically because of the saturation of peak.

--Reciprocity failure

Owing to the application of multi-layer flat-grain silver halide microcrystal with adulteration of heavy metal ion, the effect of reciprocity failure is eased.

DETAIL PROPERTIES

--Granularity

With the adoption of modern balanced multi-jet synthetic technology in the emulsion making, the emulsion crystal of multi-layer flat grain becomes uniform, regular and small-sized.
The adoption of fuzzy coupler in some sensitive layers is helpful to make image particle petty and reduce particle size visually.
The third generation DIR compounds adopted in the sensitive layer brings good interlayer effect.
The adoption of new technologies gives Super GBR400 petty particle and good texture sensation.

--Resolving power

With the application of new flat-grain silver halide microcrystal, the thickness of the coating is greatly reduced and its resolving power is increased to 100c/mm(1000:1). With the combined application of new DIR, DIAR compounds, the edge of the image becomes sharper and the pictures becomes more beautiful. Diagram 3 is to show the MTF of Super GBR400.

PROCESSING PROPERTIES

--Fast silver bleaching speed

Due to the adoption of the penetration and bleach technology and compounds concerned, the silver bleaching speed of the film processing is increased. Therefore, Super GBR400 can completely adapt C-41RA and Lucky G-70RA rapid access.
--The application of new mask technology improves the color reality and Super GBR400 is compatible with Kodak channel. Diagram 4 is the spectrum dye density cruve.

COATING STRUCTURE

Lucky Super GBR400 color film has 16 coating layers, such as, protective layer, UV filtering layer, blue sensitive layer (low and high sensitive layer), yellow filtering layer, red sensitive layer(low, midium and high sensitive layer), interlayer ,anti-halation layer, film base and anti-curl layer.

SAFE ILLUMINATION

The film handing requires total darkness.
PROCESSING
The film is intended for processing with Lucky process G-70,G-70RA or Kodak process C-41 or other equivalents.

MARK
On 135 size film edges, there are latent image printed words "LUCY SUPER GBR400" and consecutive frame numbers S, SA, 1, 1A, 2, 2A, up to 12 and 12A or 24A or 36 and 36A as well as 31digits latent image doubleway bar code which can freely select the frame number, etc. They appear clearly after processing.
On 120 size film interleaf and the packaged boxes of both 135 and 120 size film, the following content are printed: LUCKY trade mark, film name, ISO speed, emulsion number, expiry date, process and manufacturer, etc.. On 135 film cartridge, DX code is printed. Both the DX code and latent image bar code are shown in the following Form 1.

SPECIFICATIONS AND PACKAGING

STORAGE

All of high temperature, high humidity, radiation and chemical gas do harm to the photographic and physical properties of the film, therefore, the film should be kept in the original package in dry , cool, radiation free and chemical gas free places.
The general recommendatory storage temperature and relative humidity are respectively below 13 ℃and 65%.

REMARK

The film stored at low temperature should be conditioned at room temperature for 1 for 2 hours before opening the package for shooting in order to prevent condensation on film surface and degradation of the film.
The photographic properties of film may change during aging, therefore, the film should be used with the expiry date. The film loaded in camera as soon as possible.
The data and curves in this data sheet are the results under the conditions of standard exposure, process and sensing instrument. They are only an average evalutation of products and not equal to that of any certain box or roll of film.
