CRI of Lights on B&W Projects
Jonathan Jones posted a topic in LightingHello, I'm in the early stages of a project and we're heavily leaning towards black and white. My question relates to the CRI of our lighting fixtures. Considering CRI is specifically the Color Rendering Index, can we just ignore it on B&W projects? My first thought is yes, but I want to cover my bases in case I'm forgetting any beneficial qualities high-CRI lights provide beyond accurate color. Furthermore, does the answer change depending on shooting format? (B&W Film vs. Epic/Alexa Monochrome vs. shooting color and grading in post) Thanks for contributing and I appreciate your advice!
The role of L.E.D lighting in filmmaking
Aaron Takhar posted a topic in General DiscussionHi all, I am currently in the process of writing my University dissertation which is a comparative study between L.E.D lighting against traditional lighting fixtures in Hollywood film-making (such as Tungsten Halogen lighting fixtures) and was wondering if anyone could help me answer some questions on the subject. How far a role does colour rendering index play in D.O.P’s choosing Tungsten Halogen lights over L.E.D? With improved sensors able to operate in less light will this be advantageous for less powerful LED lights. Is there still a need in film-making (especially Hollywood film-making) for the bigger lighting fixtures? (e.g lighting fixtures such as the Sunray 24K Fresnel light) Thank you very much for your time.
Ektachrome/ECO to CRI green fade
Joe Rubin posted a topic in Film Stocks & ProcessingHi everyone. I'm new here so I apologize if this topic has already been sufficiently covered. I couldn't find an appropriate thread. Anyway, I'm a film archivist and I've been dealing quite a bit lately with 35mm blow-up CRIs made from 16mm Ektachrome and ECO original which have started to (or completely) gone green in the blacks. I'm assuming that this is simply the result of the weakest dyes fading but it seems as though only my CRIs that include 35mm opticals such as fades or titles have started going green and the ones that were printed directly from the Ekta or ECO and had their effects (dissolves, etc) present in the AB original edits are perfectly fine, color wise. Does anyone have any info on this? And, more importantly, is there any hope for timing it out as I begin making new protection IPs?
