KODAK PROFESSIONAL PORTRA 400 Film September 2010 • E-4050 TECHNICAL DATA / COLOR NEGATIVE FILM KODAK PROFESSIONAL PORTRA 400 is the world's finest grain high-speed color negative film. At true ISO 400 speed, this film delivers spectacular skin tones plus exceptional color saturation over a wide range of lighting conditions. PORTRA 400 Film is the ideal choice for portrait and fashion photography, as well as for nature, travel and outdoor photography, where the action is fast or the lighting can't be controlled. TECHNOLOGY 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.

Total darkness is required when you load and unload sheet film holders. 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.

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. 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.

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. Adjustments for Long and Short Exposures No filter correction or exposure compensation is required for PORTRA 400 Film for exposures from 1⁄10,000 second to 1 second. For critical applications with longer exposure times, make tests under your conditions.

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). Area Measured Density Reading KODAK Gray Card (gray side) receiving same illumination as subject 0.77 to 0.87 Lightest step (darkest in the negative) of a KODAK Paper Gray Scale receiving same illumination as subject Highest diffuse density on normally lighted forehead —light complexion —dark complexion 1.13 to 1.23 1.08 to 1.18 0.93 to 1.03 KODAK PROFESSIONAL PORTRA 400 Film • E-4050 3 SCANNING NEGATIVES IMAGE STRUCTURE You can easily scan PROFESSIONAL PORTRA 400 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. For more information, visit the following Web sites. Print Grain Index To access Go to Film Terms for KODAK PHOTO CD Imaging Workstations www.kodak.com/go/pcdFilmTerms Drivers for KODAK Film Scanners www.kodak.com/go/scannerDrivers 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.
