Characteristics
Scotch HP400 is a high speed, advanced technology, daylight balanced color print film with a nominal speed rating of ISO 400. HP400 film will provide excellent results in both compact and SLR cameras. The film may be used in a wide variety of shooting conditions and situations. This film incorporates new technologies which have vastly reduced the impact on the environment during manufacturing.
General Properties
Speed:
ISO 400/27° - Scotch HP400 has been designed to provide good picture-taking opportunities in normal to low "available light" levels and will extend effective flash distance ranges. The film also provides good picture-taking opportunities with subjects requiring high shutter speeds for action photography and hand held telephotography, and allows for smaller aperture openings for greater depth of field.
Exposure Characteristics:
New emulsion technologies have been developed and incorporated in the film resulting in a new high speed film that provides excellent results in under-exposures meeting the high quality demands of general photography. The advanced multi-layered structure ensures an excellent latitude of exposure, good results in the range of -2 to +4 stops, and high image quality for all imaging situations.
Although the film is balanced for daylight illumination, new advanced spectral sensitization assures good results when exposed under various light sources including electronic flash, tungsten and fluorescent lighting. The film also performs well outdoors during diverse color temperature conditions such as late evenings, early mornings, sky light vs. sun light and snow scenes.
Image Characteristics:
The advanced class of EXTRA-DIR couplers and color formers provide enhanced color saturation while maintaining natural skin tones and neutral gray scale reproductions in various lighting conditions. Advanced tonal linearity provides improved highlight and shadow detail.
New emulsion stabilizers yield improved processed film keeping properties and provides, during periods of handling and storage, additional protection for the film from heat, humidity, light and damaging chemical fumes.
New printing characteristics match the most common color negative profiles used by processing labs for color and density correction.
Exposure
Scotch HP400 is balanced for daylight or equivalent light conditions (5500K). When exposed under tungsten or fluorescent lighting, the use of an appropriate filter is recommended:
| Light Source | Exposure Source | Filter Requirments |
| Daylight or Electronic Flash | 400/27° | none |
| Tungsten (3200 K) | 100/21° | 80 A |
| Photoflood (3400 K) | 125/22° | 80 B |
Daylight Exposure
(Exposure time 1/500 sec.)
Use the following exposures from two hours after sunrise to two hours before sunset for average front-lit subjects:
| Lighting Conditions | Lens Aperture |
| Bright sunlight (sand or snow) | f/16 |
| Bright sunlight (distinct shadows) | f/11 |
| Weak hazy sun (soft shadows) | f/8 |
| Cloudy bright (no shadows) | f/5.6 |
| Heavy overcast | f/4 |
| Open shade | f/4 |
Note: For side- or back-lit subjects with shadow detail, increase lens aperture by 1/2 or 1 f/stop.
Existing Light Exposure
| Indoor | Shutter Speed | Lens Aperture |
| Available light from window on bright day | 1/60 | f/2.8 |
| With bright tungsten light | 1/30 | f/2.8 |
| With average tungsten light | 1/30 | f/2 |
| With bright fluorescent light | 1/60 | f/4 |
| Circus, sport events in white lights* | 1/125 | f/2.8 |
| Museum, auditorium with diffuse low light | 1/30 | f/2 |
| Outdoor | Shutter Speed | Lens Aperture |
| Twilight, scenes with no artificial light | 1/60 | f/2.8 |
| Streets at night with bright light | 1/60 | f/2.8 |
| Bright store windows, neon signs at night | 1/60 | f/4 |
| Floodlit sport events* | 1/125 | f/2.8 |
| Amusement parks, fairs at night | 1/30 | f/2.8 |
| Monuments at night with white floodlights | 1/30 | f/2 |
* Use 1/250 of a second for ice sports.
Electronic Flash Exposure
Adjust the exposure setting according to the instructions provided with the flash unit. Determine the correct lens aperture (f/stop) by dividing the guide number by the flash - subject distance in feet or meters.
Fluorescent Light Exposure
The light emitted by fluorescent tubes is generally deficient in some wavelengths resulting in prints exhibiting a green balance with standard printing procedures. Consequently, exposures made with fluorescent illumination require color corrections at time of printing. Due to the variety of fluorescent lighting color temperatures, it is not possible to recommend a particular compensation filter or set of filters.
Reciprocity
This film can be used in the range of 1/10,000 to 10 seconds without changes in speed and color balance. For exposures longer than 10 seconds, use a 20CC Y color compensating filter and increase exposure by +1 stops.
Processing
Scotch™ HP400 is intended for various process C-41 cycles and chemicals. To ensure optimum color negative quality, the process should be monitored carefully using C-41 process control strips.
Printing
Excellent standard size prints and enlargements on color paper can be obtained from Scotch HP400 using conventional enlargers or automated printing equipment. For optimal printing results with automatic printers, a dedicated channel set up with a printer control tool manufactured with this film is recommended. The extended DX barcode enables the printer to identify the film and print it on the dedicated channel.
The DX code is 85-4 (Product Code = 85, Generation Specifier = 4).
Processed film may be visually identified by orange dots between perforations and a human readable DX Code on the top edge of the film (85-4).
Storage
Before processing
Always store unexposed or exposed films in a cool, dry place in moisture-proof containers, as all color films are sensitive to heat, humidity and fumes emitted from chemicals. In hot humid climates or for long term storage, keep the films in a moisture-proof container at 10°C/50°F or lower.
- Do not open the original sealed container until just before using the film.
- Use film before the expiration date printed on the box.
- Avoid leaving a partially exposed film in the camera for a long period of time.
- Process the film promptly after exposure to avoid any image deterioration.
- Avoid storing unpacked film or 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, sprays etc.).
After processing
The dyes in Scotch HP400 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 negatives. Always keep processed negatives in a cool, dry and 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 to avoid film deterioration.
Handling
Always load and unload your camera in subdued light. Loading film in extremely low temperatures may cause the film to break.
