1920s Kodak to Dichroic Filter Design
I am interested in scientific especially laser optics , electronics , mechanism catalogs and I found that it is possible to order your special sensiometry filters from military , remote sensing filter makers.
I watched a excellent movie someone posted from kodak , it was 1920s kodachrome movie film.
It is said it was two color film and it makes two color special order dichroic filters.
Can anyone post these each of sensiometric curves of this two color film ?
I think this is the biggest step to get these excellent colors back to photography.
Thank you ,
