Base

Acetate safety base with rem-jet backing.

Darkroom, Recommendations

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

Processing

ECN-2

Storage

Store unexposed film at 13°C (55°F) or lower. For storage of unexposed film longer than 6 months, store at -18°C (0°F). Process film promptly.

Exposure Index

Tungsten (3200 K)--200; Daylight (5500 K)--125 (with Kodak Wratten Gelatin Filter No. 85)

Laboritory Aim Density

Time negative originals relative to Laboratory Aim Density (LAD) Control Film supplied by EASTMAN Kodak Company.

Color Balance

This film is balanced for exposure with tungsten illumination (3200 K). You can also expose it with tungsten lamps that have slightly higher or lower color temperatures (±150 K) without correction filters, since final color balancing can be done in printing. For other light sources, use the correction filters in the table below:

Light Source	Kodak Filters on Camera*	Exposure Index
Tungsten (3000 K)	Wratten Gelatin No. 82B	125
Tungsten (3200 K)	None	200
Tungsten Photoflood (3400 K)	None	200
Daylight (5500 K)	Wratten Gelatin No. 85	125
White-Flame Arcs	Wratten Gelatin No. 85B	125
Optima 32	None	200
Vitalite	Wratten Gelatin No. 85	125
Fluorescent, Cool White	Wratten Gelatin No. 85 + 10M	80
Fluorescent, Deluxe Cool White	Wratten Gelatin No. 85C + 10R	125
Metal Halide H.M.I.	Wratten Gelatin No. 85	125
* These are approximate corrections only. Make final corrections during printing.

Post-Production Information

When you transfer this film directly to video, set up the telecine using negative Telecine Analysis Film (TAF).

Reciprocity

No filter corrections or exposure adjustments for exposure times from 1/1000 of a second to 1 second. If your exposure is in the 10-second range, increase exposure 2/3 stop, and use a Kodak Color Compensating Filter CC10Y.

Identification

After processing, the Kodak internal product code symbol (Z), product code numbers 5274 (35 mm and 65 mm) or 7274 (16 mm), emulsion and roll number identification, and EASTMAN Keykode Numbers are visible along the length of the film.

Grain

The "perception" of graininess of any film depends on scene content, complexity, color, and density. Other factors, such as film age, processing, exposure conditions, and telecine transfer may also have significant effects. In Vision 200T Film, the measured granularity is very low.

Diffuse RMS Granularity Curves

To find the rms granularity value for a given density, find the density on the left vertical scale and follow horizontally to the sensitometric curve and then go vertically (up or down) to the granularity curve. At that point, follow horizontally to the Granularity Sigma D scale on the right. Read the number and multiply by 1000 for the rms value. Note: This curve represents granularity based on modified measuring techniques.

Sharpness

The "perceived" sharpness of any film depends on various components of the motion picture production system. The camera and projector lenses and film printers, and other factors, play a role. But the specific sharpness of a film can be measured and charted in the Modulation-Transfer Curve.

Modulation-Transfer Curves

This graph shows a measure of the visual sharpness of this film. The x-axis, "Spatial Frequency," refers to the number of sine waves per millimetre that can be resolved. The y-axis, "Response," corresponds to film sharpness. The longer and flatter the line, the more sine waves per millimetre that can be resolved with a high degree of sharpness--and, the sharper the film.

Sensitometric Curves

The center point ("N") on the x-axis corresponds to a normal exposure of an 18-percent gray card in the red, green, and blue layers of this film. A white card is 2 1/3 stops higher than normal exposure. Anything more is overexposure latitude. A 3-percent black card is 2 2/3 stops below normal exposure. Anything less is underexposure latitude.

Spectral-Senitivity Curves

These curves depict the sensitivity of this film to the spectrum of light. They are useful for adjusting optical printers and film recorders and for determining, modifying, and optimizing exposure for blue- and green-screen special-effects work.
