New gradation and color formation for outstanding dimensionality

The new ETERNA-CP DI color positive film renders dimensional reproduction of images over the entire range from shadows to highlights. Also offering highly saturated colors, the film enables rich and clear expressions from both analogue and digital sources.

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.
