I am having a frustratingly difficult time finding resources about classic lighting techniques involving large tungsten units. One would think in the last 100 years of cinema that someone would have written something down.
Every search about 10k fresnels brings up an article about the new Mole-Richardson LED, which is lovely, but not what I am after.
Does anyone have any recommended reading about lighting techniques before the HMI was invented? I've got plenty of resources from the 1920's forward, which are very interesting, but nothing about techniques in the 50's - 80's. I'm more interested in the techniques of making hard light look soft, from those masters of lighting we have lost in the past several years. These resources seem the most difficult to find.
Any suggestions are appreciated.
