where D] 2.0: density of original film
corresponded to the density
D-2.0 of duplicated image.
Di 0.3: density of the original film
corresponded to density
D=0.3 of duplicated image.
The image contrasts of all duplicated images are shown in
Table 3,
The image contrast of all duplications which were directly
printed from the original negative film #2445 were about 1:6.0.
This means that only the targets which have the image contrast
of 1:6 on the orininal image can be reproduced by the duplication,
The duplicated images produced through the duplication
processes as (2445-4109-CCP) and (2445-4109-6110) were found |
to have a high image contrast of more than 1:10. (€
The image contrast of the duplicated image from the original
color positive #2248 was relatively high as 1:10 when Chiba-
chrome CCP paper was used, The lower image contrast of
1;6-7 was attained when Kodak 14RC or 37RC paper were used,
whether the inter-negative film was utilized or not,
4-2 COLOR REPRODUCTION
Reproduction of color patchs, consists of 8 saturated and
8 pale colors, were measured by the microspectro radiometer and
their CIE u-v chromatiaties and the color difference from that
of the original film, were calculated,
The color differences were plotted in Fig, 18.
The color negative $2445 was printed on the color positive film
#4109 and compared with the film #2448. Both film had not
reproduced the well saturated blue and magenta colors, qe
In respect of 8 pale colors, the reversal color film #2448
had a better reproduction than #2445,
Fig. 19 indicates that the color reproduction of the
duplicated positive film reprinted from the film #2448,
In this figure, R3, Gq, Bi, ..... indicate the chromaticity
coordinates of the pale color and R5, G5, ...».. Of the saturated
color.
The film #2447 had same reproducibility as #2448 from a
stand point of the mean color difference, but their hue shifts
