My quest continues to understand and make it stand the technology of 30s to 70s European and American best lenses.
In time , I thought high low aberration per lens element in an objective plays as an unsharp masking filter.
Second idea came later ,
- I have an Kodak Ektar 111mm f:1.5 Fluroride lens and when I look to my mother , it looks as someone claimed as kodachrome or leica look. All the skin looks like shiny polyurethane lacquer coated plastic , everything is round , flawless and relief like , all skin wrinkles are deeper and shadows are deeper.
It makes a dry skin looks like oil coated. That strong effect.
- I watched a bolex movie and swiss made yvar lens was UNBELIEVABLE. All the colors were so strong and elegant and skin looks like a inflated baloon , not less. The face corners , cheeks , nose end was 3 tone brighter and it looks like it was glowing.
I learned that dichroic glasses and coatings cut some wavelenghts and saturates the image
I thought that dichroic technology would be the responsiple of all above experiments.
I want to learn what is the way of detection of dichroic glasses and coatings at a objective ? How they would relieve themselves ? What is the technology to detect and analysis them ?
