Description

This family of color negative films delivers an extra punch of color. KODAK PROFESSIONAL ULTRA COLOR Films / 100UC and 400UC feature deep, saturated color to bring subjects to life, without sacrificing skin tones. Both film offer extremely fine grain for smooth enlargements through both optical prints and digital film scans, as well as outstanding sharpness for capturing fine detail.

Use KODAK PROFESSIONAL ULTRA COLOR Films / 100UC and 400UC for fashion, landscape, nature, wildlife, and lifestyle photography. KODAK PROFESSIONAL ULTRA COLOR Film / 400UC provides extra speed for low light and action situations.

Storage and Handling

Store unexposed film at 21°C (70°F) or lower in the original sealed package. For extended periods, store film at 13°C (55°F) to preserve consistency.

To avoid moisture condensation on film that has been refrigerated, allow the film to warm up to room temperature before opening the package. Typical warm-up times are given in the table below.

Load and unload roll-film cameras in subdued light.

Process film as soon as possible after exposure. Protect negatives from strong light, and store them in a cool, dry place. For long-term storage, keep negatives at a temperature between 2°C (35°F) and 13°C (55°F) and at a relative humidity between 30 and 35 percent.

Darkroom Recommendations

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

Exposure

Film Speed

Use the speed numbers in the tables below with cameras or meters marked for ISO, ASA, or DIN speeds or exposure indexes (EIs). Do not change the film-speed setting when metering through a filter. Metering through filters may affect light meter accuracy; see your meter or camera manual for specific information. For critical work, make a series of test exposures.

Adjustments for Long and Short Exposures

No filter correction or exposure compensation is required using 100UC and 400UC Film for exposures from 1/10,000 second to 10 seconds. For critical applications with longer exposure times, make tests under your conditions.

Daylight

Use the exposures in the table below for average frontlit subjects from 2 hours after sunrise to 2 hours before sunset.

Electronic Flash

Use the appropriate guide number in the table below as starting-point recommendations for your equipment. 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. If negatives are consistently too dense (overexposed), use a higher guide number; if they are too thin (underexposed), use a lower number.

Fluorescent and High-Intensity Discharge Lamps

Use the color-compensating filters and exposure adjustments in the tables below as starting points to expose these 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 discharge lamps, use exposure times of 1/125 second or longer.

Processing

Process these films in KODAK FLEXICOLOR Chemicals for Process C-41 with the following replenishment and wash rates.

Judging Negative Exposures

You can check the exposure level with a suitable electronic densitometer equipped with a filter such as a KODAK WRATTEN Gelatin Filter 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 these red density values for a normally lit forehead only as a guide. For best results, use a KODAK Gray Card (gray side).

Retouching

You can retouch the sheet and 120 / 220 sizes on both the base side and the emulsion side. Retouch only the emulsion side on the 135 size.

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

Printing Negatives

This film is optimized for printing on KODAK PROFESSIONAL SUPRA ENDURA and ULTRA ENDURA Papers, and KODAK PROFESSIONAL ENDURA Metallic Paper.

Make color slides and transparencies by printing the negatives on KODAK PROFESSIONAL ENDURA Transparency Display Material or KODAK PROFESSIONAL ENDURA Clear Display Material.

Make black-and-white prints on any of the materials mentioned above using the recommendations in KODAK Publication CIS-274, Printing Black-and-White Images Without KODAK Black-and-White Papers.

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 —

Scanning Negatives

You can easily scan KODAK PROFESSIONAL Film negatives with a variety of linear-array-CCD, area-array-CCD, and PMT film scanners. You can scan negatives on desktop 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.

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.
