Zone System equates to Stops ?
Ram Nanda posted a topic in General DiscussionAnsel Adams devised a 11 Zone system. Can this be equated to 11 exposure zones ? Current film or Digital sensors are rated as 15 stops of dynamic range. Does that mean 15 Zones or 15 Stops fit into 11 Zone system (like 1.36 stop per zone) ? HDR output is like 20 stops of dynamic range. Does it mean 20 stops fit into 11 zones ? And what is exposure latitude in relation to these ? Can some one please explain this ?! some times it is confusing.
Using a light meter for digital video
Matt Iacono posted a topic in General DiscussionHello, When you are metering a scene, do you meter for the camera's dynamic range, or for the 6 stops in SDR or the 13+ stops in HDR? For instance, if your camera has 6 stops of highlight dynamic range, and 8 stops of shadow dynamic range, do you keep everything in your scene between those 14 stops or do you keep everything in between the lets say 6 stops of standard dynamic range? I hope this question makes sense! Thanks in advanced to anyone who can help! - Matt
Benjamin Leggett posted a topic in AC's & DIT'sHi, I'm Ben, a learning camera assistant who chose not to study film and is now catching up on production etiquette and techniques! I recently pulled focus on a short film for a great DoP (Tansy Simpson) here in London and at one point she asked me to push the iris to a 'two plus' Now i assumed this meant something like a t2.1, or did it mean 2.5? I'd love to get clarification on this as I was too worried she might think I was an amateur if i asked! Thanks in advance for any help offered, Benjamin
