Making Partial Dispersion Response Filter, Look for Dyes, Powders for Use in Acrylic
My 110mm f:1.5 Ektar , Summitar , Elmar and Sonnar is strongly shows monochromatic reddish orange partial dispersion glass response to dim light When it happens , may be because of easy to correct a lens to monochromatic light , all the qualities increases folded. All spatial detail response and quantity increases , skin details , relief effect , shadows , shadows on face lines increases and it turns to a image like an image painted with Rembrandt when he is older under mum light. If you look in to rembrandt portrait in the dim light , he uses thousands of thick brush strokes and reddish orange colors.
An similar thing occurs on Da Vinci Paintings and the thick lacquer medium after oxidised and aged , his paintings have a dark deep coating with making person very excited to find this amount of load of spatial information.
Now , I defend these qualities since I entered the forum but my lack of knowledge was short to describe the effect.
And Now I want to coat a uv filter with spinning a partial dispersion dye, nano powder, semiconductor powder added acrylic to sell to the photographers who uses lenses without expensive nonlinear glass. I am thinking to cast a big 3 element anamorphic cylinder lens used objective but this is still to be researched.
There are scientists at the group who can shed more light to sourcing , mixing , final effect or anything I could not visioned.
If I find dyes , rare earth nano powders or semiconductor powders affordable or any nano gold, silver, copper powder could be manufactured with Turkovich method, I would be glad.
This idea is new to me , I will post my findings here also.
