Overview
From deepest shadows to brightest highlights, well-balanced image reproduction
The newly released ETERNA-CP Type 3512 is highly evolved in terms of contrast and color balance, providing natural, well-balanced image reproductions for a variety of scenes.

In order to simulate conditions closest to practical use, exposure was made under a 2854K Tungsten light source, through CC-90Y and CC-60M print color correction filters and a Fuji SC-41 ultraviolet absorbing filter in combination. Processing was carried out under standard conditions and the three color densities (status A) were measured. The results of measurements are plotted as characteristic curves. Curves G and B are shifted 1.0 Log H to avoid overlapping.
