Characteristics
ScotchChrome™ 100 is a medium speed, color reversal film with important improvements in color reproduction, image characteristics, storage and processing properties.
This film, balanced for exposure in daylight or electronic flash, is intended for standard E-6 processing.
ScotchChrome 100 is designed to produce high quality transparencies for direct projection, for printing on reversal color paper and film, and to be used as original in graphic arts applications.
General Properties
Speed:
ISO 100/21° for exposure in the range of 1/2 to 1/10,000 of a second. This medium speed is ideal for most picture-taking situations in daylight with electronic flash or blue flashbulbs.
Image characteristics:
Very fine grain and high sharpness ensure optimal reproduction of the original scene.
Color reproduction:
Improved yellow sensitization and cyan and magenta couplers provide extremely brilliant and highly saturated colors. Colorimetric characteristics ensure compatible performance in printing and graphic arts applications.
Storage characteristics:
In developing this film, special care was taken to provide the emulsion with superior stability and protection against noxious agents caused by improper storage (high temperature, high humidity, fumes, etc.) to ensure consistent quality throughout the product life.
Dye stability:
The emulsion provides high resistance to dye fading when subjected to prolonged projection. It also demonstrates superior dark storage characteristics.
Process E-6 compatibility:
Features incorporated in the emulsion provide improved film performance, consistency and reproducibility in various E-6 processes particularly in marginal bleach conditions.
Exposure
This film is balanced for daylight or equivalent light conditions with an average color temperature of 5500K.
Light Sources and Filters
| Light source | Filter | ISO Speed Rating |
| Daylight | -- | 100/21° |
| Electronic Flash | -- | 100/21°* |
| Blue Flashbulbs | -- | 100/21° |
| Skylight, Mountain, Seashore, Aerial Scenes, Daylight Overcast | Skylight 1A | 100/21°** |
| Halogen or Photoflood Lamps 3400K | 80B | 32/16° |
| Studio or Tungsten Lamps 3200K | 80A | 25/15° |
*When the results are consistently too blue, use an 81B filter and speed rating of ISO 80/20°.
**A skylight 1A filter is useful to reduce the slight bluish cast that occurs on pictures taken in mountains, on snow, at the seashore, in overcast conditions, in shade under blue sky and in aerial scenes.
Daylight Exposure: Exposure time 1/250 sec.
| Lighting conditions | Lens aperture |
| Bright or hazy sun on sand or snow | f/16 |
| Bright or hazy sun with distinct shadows | f/11 |
| Weak hazy sun with soft shadows | f/8 |
| Cloudy bright-no shadows | f/5.6 |
| Heavy overcast | f/4 |
| Open shade | f/4 |
Note: For side or back-lighted subjects with shadow detail, open lens apertune 1/2 to 1 stop. To reduce deep shadows on open sunshine close-ups, use of a flash fill is recommended.
Exposure with Electronic Flash and Blue Flashbulbs
The exposure setting should be adjusted according to instructions with your flash unit, flashcubes or blue flashbulbs using the guide number related to a film speed of ISO 100/21°. Determine the correct f/stop by dividing the guide number by the camera-to-subject distance in feet or meters. It is often advisable, when using a new film with your electronic flash, to run a basic exposure test to ensure that the published guide numbers for the flash unit are correct. If your results are consistently too blue, use an 81B filter and a film speed of ISO 80/20°.
Exposure with Fluorescent Light
For exposure under fluorescent lights, only general guidelines for testing are possible due to the large number of lamp types and the great difference in their emission spectra. For "cool-white" fluorescent bulbs, use a 30M color correction filter with a speed of ISO 64/19° as an initial trial. With "warm-white' use 30C + 30M filter with a speed of ISO 50/18°.
Reciprocity
For exposure times longer than 1/10 second, it is necessary to compensate for reciprocity characteristics. Suggested data for trial purposes are contained in the following table:
| Exposure times | From 1/10,000 to 1/10 sec. | 1 sec. | 10 sec. | 100 sec. |
| Exposure Correction | none | +2/3 stop | +1 1/2 stops | + 2 1/2 stops |
| Color Compensating Filter (CC) Correction | none | CC05Y | CC10R | CC15R |
Storage of Films Prior to Processing
Like all color films, ScotchChrome 100 is sensitive to heat, humidity and fumes emitted from chemicals.
Always store unexposed or exposed films in a cool, dry and dark place in moisture-proof containers.
Use film before the expiration date printed on the box.
Do not open the original sealed container until just before using the film.
Avoid leaving film and loaded cameras near heat sources or in hot places such as in a car parked in the sun.
Avoid storing unpackaged film and loaded cameras in high humidity conditions or where the emission of exhaust gases and formaldehyde fumes may occur as these are very harmful to photographic films (aldehyde fumes are often emitted from new furniture, wood glues, laminate adhesive, foam insulation, perfumes, deodorants, aerosol sprays, etc.).
Avoid leaving a partially exposed roll of film in the camera for a long period of time.
Process exposed films promptly to avoid any image deterioration.
In hot, humid climates, keep unexposed and exposed films in a refrigerator in a moisture-proof container at 10°C/50°F or lower.
Storage of Processed Films
The dyes in ScotchChrome 100 are among the most stable used for sensitized material. Yet, like all organic dyes, they may change with time. Humidity, heat and light are the most critical factors in the storage of processed color slides. Always keep processed slides in a cool, dry, dark place. It is advisable to store processed film at a relative humidity not exceeding 40% and a temperature not exceeding 20°C/68°F.
Processing
This film is intended for standard E-6 processing. The features of this film make it possible to compensate for over and underexposure by changing first developer times. We suggest, as a starting point, the following modification to the processing time:
| Exposure Index ISO | | Suggested First Developer Time |
| 200 | 1 stop push | 8 minutes |
| 100 | Normal exposure | 6 minutes (normal time) |
| 50 | 1 stop pull | 4 minutes |
Printing
Excellent standard-size prints and enlargements can be obtained from ScotchChrome 100 transparencies on color reversal paper or film. This film is also suitable for photomechanical color separation.
Handling
Always handle this film in subdued light when loading or unloading the camera. Loading film in extremely low temperatures may cause the film to break.
Darkroom Handling
ScotchChrome 100 film must be handled in complete darkness.
Diffuse Granularity: 13.0 RMS
Note: The sensitometric curves and data represent product tested under the conditions of exposure and processing specified. They represent production coatings and, therefore, do not apply directly to a particular box or roll of photographic material. They do not represent standards or specifications which must be met by Imation. Imation reserves the right to change and improve product characteristics at any time.
