ETERNA 250

Overview

Expanded exposure range for enhanced shadow quality

Warm colors and smooth, consistent gradation enable extremely natural facial tones. Highly suitable for telecine transfer, ETERNA 250 can be used seamlessly with high-speed ETERNA 500.

In order to simulate conditions closest to practical use, exposure was made under a 3200K light source, through a Fuji SC-41 ultraviolet absorbing filter. Processing was carried out under standard conditions and the three color densities were measured, producing the results indicated in the graph above.
