KODAK PROFESSIONAL EKTAR 100 Film February 2010 • E-4046 TECHNICAL DATA / COLOR NEGATIVE FILM KODAK PROFESSIONAL EKTAR 100 Film is the world's finest grain color negative film. With ISO 100 speed, high saturation and ultra-vivid color, this film offers the finest, smoothest grain of any color negative film available today. An ideal choice for commercial photographers and advanced amateurs, KODAK PROFESSIONAL EKTAR 100 Film is recommended for applications such as nature, travel and outdoor photography, as well as for fashion and product photography. TECHNOLOGY 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.

Daylight Fluorescent and High-Intensity Discharge Lamps Use the exposures in the table below for average frontlit subjects from 2 hours after sunrise to 2 hours before sunset. Use the color-compensating filters and exposure adjustments in the tables below as starting points to expose KODAK PROFESSIONAL EKTAR 100 Film 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.

Adjustments for Long and Short Exposures No filter correction or exposure compensation is required for exposures from 1⁄10,000 second to 1 second. For critical applications with longer exposure times, make tests under your conditions. 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. * Unit Output (BCPS)* Guide Number Distances in Feet/Metres 350 40/12 500 50/15 700 60/18 1000 70/21 1400 85/26 2000 100/30 2800 120/36 4000 140/42 5600 170/50 8000 200/60 KODAK Color Compensating Filter(s) Exposure Adjustment Warm White 40B + 40C +2 stops Warm White Deluxe 40B + 50C +2 stops Cool White 30B +1 stop 40C + 10M +1 stop KODAK Color Compensating Filter(s) Exposure Adjustment High-Pressure Sodium Vapor 50B + 70C +2 2/3 stops Metal Halide 5C + 10M +2/3 stop Mercury Vapor with Phosphor 30B + 5C +1 stop 80R +1 2/3 stop Cool White Deluxe High-Intensity Discharge Lamp (CCT) Mercury Vapor without Phosphor BCPS = beam candlepower seconds 2 KODAK PROFESSIONAL EKTAR 100 Film • E-4046 PROCESSING RETOUCHING Process EKTAR 100 Film in KODAK FLEXICOLOR Chemicals for Process C-41 using the replenishment and wash rates in the tables below. Note that the developer replenishment rates are starting-point recommendations only and may vary due to the amount of exposure to the film, scene content, and the presence/absence of sprocket holes. You can retouch the 120 and sheet sizes on both the base side and the emulsion side. Retouch only the emulsion side of 135 size film. For information on retouching equipment, supplies, and techniques, see KODAK Publication No. E-71, Retouching Color Negatives.

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 KODAK Gray Card (gray side) receiving same illumination as subject 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 Density Reading 0.77 to 0.87 This film is optimized for printing on KODAK PROFESSIONAL SUPRA ENDURA, SUPRA ENDURA VC Digital, ULTRA ENDURA, ULTRA ENDURA High Definition, and PRO IMAGE II Papers, and on KODAK PROFESSIONAL ENDURA Metallic VC Digital 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.

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 Film Terms for KODAK PHOTO CD Imaging Workstations Drivers for KODAK Film Scanners 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.
