The new generation of 35mm color film, recently launched by Kodak, Fuji and 3 m, will provide better and brighter colors, extraordinary skin tones, very fine textures, in some cases, it is 2 1/2 times faster than the fastest ISO emulsion now.
All this means to the photographer that, so far, only a larger format camera can get the quality, and it is now possible to have 35mm devices.
The new film is indeed different in individual features --
Some are warmer in tone, while others are cooler.
These changes allow photographers to use these movies as they sit under the control of complex color consoles
With a variety of different types of movies, users can master the most difficult situations by choosing the one that best suits the topic at hand.
For example, a sports and action photographer will be able to select an ISO 1000 color film to "stop" the action at the fastest speed, and at the same time, he will be able to use a smaller lens opening to increase the depth of field.
Natural photographers can use slower color films to make walls
The enlarged color print has no texture and is very faithful to the original theme.
The first company to announce the results of the new film technology is Eastman Kodak.
Use a kind called DIR (development-inhibitor-releaser)technology)
Chemistry enhances edge effects such as eyebrows and grass leaves, greatly improving the overall clarity of the image.
This is achieved during development by suppressing molecules designed to compensate for light
Scattering and internal diffusion effects that make the edges look blurry.
Advertising further advanced the process, and Kodak engineers also incorporated DIR into the film's fast magenta and green layers to increase speed and color reproduction to ensure finer particles, and provide especially insufficient exposure.
Some knowledge about advertising
A branch of how the company's remarkable development of disc films is, it has proven that it is able to produce high-quality color amplification from color negatives smaller than your nails.
All these advances are reflected in four new Kodak films: Kodak VR100, 200, 400 and 1000 (
Numbers represent ISO speed in each case).
100 and 200 films are the sharpest Kodacolor films ever put on the market.
They are able to easily render fine details and complex textures.
The particles of the two are the same size, but the slower film is slightly better in terms of image clarity.
The VR 400 film has improved a little more than the 400 on the market now, as it has a much finer texture and sharpness, and the flesh color has improved.
Kodacolor VR1000 is a blockbuster.
It will open up an unprecedented field of photography.
This film can be used in very low lighting areas.
For example, a photo can be taken with the light of a candle, or it can be blurred --
Sports venues.
An additional advantage shared by the entire team is the wide exposure range;
These films will be dealt with successfully. and over-
Exposure for up to two stops.
This, coupled with the speed of fastestfilm, makes it possible to expose it with an incredible ISO rating of 4000.
This will result in an extra sense of particles, increase contrast and reduce clarity, but speed is urgent when needed.
Fuji has also been improving the quality of the film.
The company has developed a kind of DSG (
Double structure grain)
New concept of particle crystal growth in thin films.
These particles have a double structure.
Case for DSG trap photos-
Electrons are in the process of exposure, while the kernel controls particles during development.
By separating these two functions, Fuji engineers have improved the efficiency of light utilization, while also producing very fine grains. The last DIR (Developer-Inhibitor-Releaser-Coupler)
Release an inhibitor during development to enhance color brightness and image clarity.
This new technology has been integrated into the rattan HR100 and 400 (
HR stands for high resolution).
There are two movies.
Spectral sensitivity based
Ability to handle indoor and outdoor lighting situations, even if special color correction filters are not used).
However, to get the best results, these movies perform best during the day or under an electronic flash.

3 m Company chose high speed.
Their latest film, ISO 1000, is the fastest color slide film in the world, 1/2 times faster than any other slide film.
For photographers who are interested in action, drama, and underwater photography, this is the ideal choice, and it is also a very good choice for long term shots, in the long term shots, the camera
This is a daylight balanced color slide that will also perform well under the electronic flash.
For photographers who have to take pictures indoors under tungsten lamps at night, 3 m is also the fastest indoor color slide film, ISO 640 T (
T for tungsten)
Works well with stage, stadium lighting and drama scenes.
Both films can be chemically treated with the traditional E6.
Both may be "pushed" by credible results ".
I have some results when comparing different brands of these movies: Comparing Kodak's 100 with Fuji's 100, I found Kodak's movie a little "warm ", "This makes it a great choice for rainy weather where it can provide excellent color reproduction without filtering.
Fuji's "cool" performance produced a good color in the early morning or later in the afternoon, when the sun was usually very reddish.
When comparing Kodacolor VR 1000 and 3 m 1000, it must be remembered that this is indeed an Apple --verses-
Because Kodak's film is a color negative and 3 m is a color slide film, The Orange case.
Perhaps it is because of this difference that Kodak film is a little smaller than 3 m and a little more latitude.
Polaroid's new 35mm automatic processing system is another new entry in the field.
Around a series of new color films and blackand-
White film available for any 35mm camera and special automatic processor (
Less than $100)
, The system provides immediate development and viewing in broad daylight-
No darkroom is required, and no washing, drying or precise temperature control is required.
This is how it works.
After exposing the film in the camera in the usual way, the special Polaroid film is re-wound into its cartridge and put into the automatic processor together with its matching processing package (
The quantity of chemicals containing a roll of film in the package is just right).
The cover of the automatic processor is closed, the lever is pressed, and the processing crank is turned.
A strip appears from the processing packaging and evenly coated with the processing fluid, which is then laminated to the exposed film.
Then, wrap the strip and the exposed film together on the Strip
On the reels, they stay in touch for 60 seconds, which is necessary for film development.
At the end of 60 seconds, the control lever is moved back to its original starting position, the processing crank is turned again, and the processed film is poured back to its original cartridge.
At the same time, the waste layer of the Strip and the processed film and any unused processing chemicals can be returned to the disposable processing box.
Next, open the automatic processor, discard the processing box, and transfer the film it developed to the 35mm Polaroid 35mm slide frame.
The specially designed plastic sliding bracket enters the other end of the bracket, the dry, developed frame is cut and quickly installed with minimal film handling.
Finished color or black-and-
White clear film can then be viewed or projected.
Three films will be processed automatically at the beginning; (1)
Polachrome CS 35mm color transparent film, balanced during the day, ISO is 40. (2)Polagraph HC (High Contrast)black-and-
Transparent White (slide)
Film with ISO 400. (3)
Polapan CT 35mm continuous color black-and-
Transparent White (slide)
Film with ISO 125.
Prices have not yet been published as of the time of writing, but are said to compete with existing film and development costs.

New color movie: faster, clearer and brighter.
