Slide 2 Vacation at the Lake
When studying the color images of the '30's and '40's, two things were most apparent; the clarity of the photograph and the color.
The level of detail, even when enlarged, was jaw dropping.
As for the color, after much experimentation, it appears that the saturation has been reduced, the mid tones have more blue and the shadows contain a lot of green.
When it all comes together, you have the look of a faux vintage transparency.
