Description

This new family of commercial color negative print films offers superior image structure, bold/dynamic color, and natural skin tones. They are an excellent choice when negatives will be electronically scanned. KODAK PROFESSIONAL SUPRA Films are designed for exposure with daylight or electronic flash.

KODAK PROFESSIONAL SUPRA 100 Film features extremely fine grain and excellent sharpness, allowing for a high degree of enlargement. This film is an excellent choice for fashion, landscape, nature, product, lifestyle, and medical photography.

KODAK PROFESSIONAL SUPRA 400 Film offers the finest grain of any color negative film in its speed class, plus vibrant colors without oversaturated skin tones. In addition, a new emulsion overcoat makes the negatives more scratch resistant for improved scans and prints. Suggested applications include fashion, wildlife, sports, news, lifestyle, and product photography. This film can also be push-processed one stop with good results.

KODAK PROFESSIONAL SUPRA 800 Film is the sharpest high-speed color negative film available today. It also delivers superior color saturation, even when underexposed. SUPRA 800 Film can be push-processed up to EI3200 with minimal impact on grain, contrast, color, and shadow detail. Use this film to capture sports, action, news, and runway fashion events.

Available Sizes

Sizes and catalog (CAT) numbers may differ from country to country. See your Kodak dealer who supplies KODAK PROFESSIONAL Products.

Storage and Handling

Load and unload film in subdued light.

Store unexposed film at 70°F (21°C) or lower in the original sealed package. Process film as soon as possible after exposure. Protect negatives from strong light. For more information about storing negatives, see KODAK Publication No. E-30, Storage and Care of KODAK Photographic Materials—Before and After Processing.

Note: High speed films, such as SUPRA 800 Film, are sensitive to environmental radiation. Expose and process this film promptly. As exposure to radiation is cumulative, you may also want to request visual inspection of SUPRA 800 Film at airport and other security x-ray inspection stations.

Darkroom Recommendations

Do not use a safelight. Handle unprocessed film in total darkness.

Exposure

Exposure Compensation

For light sources other than daylight, use the filtration and exposure compensation in the table below.

Daylight

Recommended exposures in the table below are for frontlit subjects from 2 hours after sunrise to 2 hours before sunset when you expose each of these films at its nominal speed.

Fluorescent and High Intensity Discharge Lamps

Use the color-compensating filters and exposure adjustments in the tables below as starting points to expose SUPRA Films under fluorescent or high-intensity discharge lamps. For critical applications, make a series of test exposures under your actual conditions.

To avoid the brightness and color variations that occur during a single alternating-current cycle, use exposure times of 1/60 second or longer with fluorescent lamps; with high-intensity lamps, use exposure times of 1/125 second or longer.

Electronic Flash:

Use the guide numbers in the table below as starting-point recommendations for your equipment when you expose these films at its nominal speed. Select the unit output closest to the number given by your flash manufacturer. Then find the guide number for feet or metres. To determine the lens opening, divide the guide number by the flash-to-subject distance.

Adjustments for Long and Short Exposures

For SUPRA 100 and SUPRA 800 Films, no filter corrections or exposure adjustments are required for exposure times of 1/10,000 to 1 second; for SUPRA 400 Film, no adjustments are required for exposures from 1/10,000 second to 10 seconds. At longer exposure times, exposure compensation is required.

Processing

Process these films in KODAK FLEXICOLOR Chemicals for Process C-41.

Judging Negative Exposures

You can check the exposure level with a suitable electronic densitometer equipped with a filter such as a KODAK WRATTEN Gelatin No. 92 or the red filter for Status M densitometry. Depending on the subject and the light source used for exposure, a normally exposed and processed color negative measured through the red filter should have the approximate densities listed below.

Because of the extreme range in skin color, use the red density values for a normally lit forehead only as a guide. For best results, use a KODAK Gray Card (gray side), KODAK Publication No. R-27.

Retouching

Retouch only the emulsion side; apply KODAK Retouching Fluid before using KODAK Retouching Pencils.

For information on retouching equipment, supplies, and techniques, see KODAK Publication No. E-71, Retouching Color Negatives.

Scanning Negatives

You can easily scan SUPRA Film negatives with a variety of linear-array-CCD, area-array-CCD, and PMT film scanners. You can scan negatives on desk-top scanners as well as high-end drum scanners.

Because no standards exist to define the colored filter sets that film scanners use to capture the red, green, and blue information of the film image, each manufacturer's scanner has its own characteristic output. The output depends on the scanner's sensitivity to the dyes in the film. This sensitivity is determined by the spectral distribution of the colored filter sets and/or the spectral sensitivity of the charge-coupled-device (CCD). In addition to these spectral specifications, scanner output depends on the look-up tables or matrices that the scanner uses to output information for CRT monitors, transmission, etc. These tables or matrices are part of either "plug-in" programs used with specific software packages designed for image manipulation, updateable ROMs included with the equipment, or fixed algorithms for calibrating and balancing, similar to those used in photographic color printing equipment.

The generic "color negative film" channel designation available with scanner software is only a starting point. You can adjust the final color balance and the scene-dependent contrast and brightness of an image by using the scanner's controls during pre-scan, or by using an image-manipulation software program or workstation after acquisition. Some scanners allow you to use "plug-in" programs to customize scanner setups.

Printing Negatives

This film is optimized for printing on KODAK PROFESSIONAL SUPRA III and ULTRA III Papers, and on KODAK PROFESSIONAL DURAFLEX Print Material.

Make color slides and transparencies by printing the negatives on KODAK VERICOLOR Slide Film, VERICOLOR Print Film or on KODAK PROFESSIONAL DURATRANS Display Material, or KODAK PROFESSIONAL DURACLEAR Display Material.

Make black-and-white prints on KODAK PANALURE SELECT RC Paper for conventional black and white processing, or on KODAK EKTAMAX RA Professional Paper for Process RA-4.

These films are similar in aim printing density to the family of KODAK PROFESSIONAL PORTRA Films. To set up a color printer or negative analyzer, use the following control negatives.

Digital Files

You can scan your image to a file and print digitally to—

KODAK PROFESSIONAL Digital III Color Paper

KODAK PROFESSIONAL DURATRANS Digital Display Material

Image Structure

Print Grain Index

The Print Grain Index number refers to a method of defining graininess in a print made with diffuse-printing illumination. It replaces rms granularity and has a different scale which cannot be compared to rms granularity.

• The method uses a uniform perceptual scale, with a change of four units equaling a just noticeable difference in graininess to 90 percent of observers.
• A Print Grain Index rating of 25 on the scale represents the approximate visual threshold for graininess. A higher number indicates an increase in the amount of graininess observed.
• The standardized inspection (print-to-viewer) distance for all print sizes is 14 inches, the typical viewing distance for a 4 x 6-inch print.
• In practice, larger prints will likely be viewed from distances greater than 14 inches, which reduces apparent graininess.
• Print Grain Index numbers may not represent graininess observed from more specular printing illuminants, such as condenser enlargers.

For more information, see KODAK Publication No. E-58, Print Grain Index—An Assessment of Print Graininess from Color Negative Films.

These graphs are designed to be printed in landscape mode. They will print properly on most printers in their current page set-up of 100%. However, some printers may require adjustments to the browser page set-up in order to have the graph print on a single 8 1/2 x 11 inch sheet of paper.
