MDL – NVidia Material Definition Language
www.nvidia.com/en-us/design-visualization/technologies/material-definition-language/
THE NVIDIA MATERIAL DEFINITION LANGUAGE (MDL) gives you the freedom to share physically based materials and lights between supporting applications.
For example, create an MDL material in an application like Allegorithmic Substance Designer, save it to your library, then use it in NVIDIA® Iray® or Chaos Group’s V-Ray, or any other supporting application.
Unlike a shading language that produces programs for a particular renderer, MDL materials define the behavior of light at a high level. Different renderers and tools interpret the light behavior and create the best possible image.

TERMINOLOGY USED on FILM SETS
www.ubcp.com/wp-content/uploads/Terminology-on-Film-Sets.pdf
TERMINOLOGY USED on FILM SETS
“10-4”: Short for “I understand” or “copy.”
“10-100”: Short for “Going to the honey wagon”; a trip to the bathroom.
“What’s your 20?” Short for “Where are you?”
“Action”: Director’s cue for the actors and/or action to begin.
“Back to First Marks”: Instruction for actors/extras to return to their first positions; also referred to as “Ones.”
“Background”: Cue for extras and any other background action elements to begin their action.
Call Time: The time you must be on set or location, ready to work.
Circus: Makeup, Hair and Wardrobe Trucks, Honey wagons, Mobile Dressing Rooms and Catering.
Company Move: Short for “We’re on the move’; this means that the entire unit is finished at that location and is
“Cut”: The call to stop the action. Before releasing any lock-up make sure you hear cut from the 1st AD.
Day for Night: Using special camera lenses, lighting and film stock to create a night look during the day.
Exterior: Outdoor shot
Extras: Performers hired to provide background action; also known as the “background performers”.
Genie Lift: A raising platform/crane used mainly for high angle shots and lighting for exterior night shots.
“Go Again”: Repeat the same shot. (Get used to hearing this one).
Honey-wagon: Washroom truck.
Hot Set: The set is ready for shooting and must remain exactly as is for continuity (high priority).
Interior: Indoor shot.
“Lock It Up”: Short for “Be quiet and get ready for cameras to roll
Martini Shot: Last shot before wrap; also “Window Shot”
MOS: Mute On Screen. Camera is rolling but not recording sound.
Pick-Up: Re-filming part of a scene from a specific point in the action.
“Picture’s up”: Rehearsal is complete; cameras will roll on the next action.
“Roll Camera”: Cue to the camera operator to begin rolling film.
“Roll Sound”: Cue to the sound mixer to begin recording sound.
“Rolling”: Film and sound are rolling, action is about to begin. Be quiet and still!
Room Tone: Recording dead air (no dialogue) for matching sound ambience during post-production. Be quiet!
“Speed”: Response heard from Sound Mixer after “Roll Sound”, meaning that themachine is up to speed.
“Stand By”: Hold your positions for a temporary delay, and be prepared for rolling.
Star Wagon: Mobile dressing room for actors
Tow Shot: A sequence where a picture car is towed by a camera truck for traveling car scenes.
“Turn Around”: Reversing the camera angle 180 degrees. This is not to be confused with crew turnaround, which is the
required rest period between workdays.
Wild Sound: Recording specific dialogue or sounds without the camera rolling, for editing purposes; also “wild lines.”
Wrap: The end of the shooting day (finally!). -
Photography basics: How Exposure Stops (Aperture, Shutter Speed, and ISO) Affect Your Photos – cheat sheet cards

An exposure stop is a unit measurement of Exposure as such it provides a universal linear scale to measure the increase and decrease in light, exposed to the image sensor, due to changes in shutter speed, iso and f-stop.
+-1 stop is a doubling or halving of the amount of light let in when taking a photo
1 EV (exposure value) is just another way to say one stop of exposure change.
https://www.photographymad.com/pages/view/what-is-a-stop-of-exposure-in-photography
Same applies to shutter speed, iso and aperture.
Doubling or halving your shutter speed produces an increase or decrease of 1 stop of exposure.
Doubling or halving your iso speed produces an increase or decrease of 1 stop of exposure.
Because of the way f-stop numbers are calculated (ratio of focal length/lens diameter, where focal length is the distance between the lens and the sensor), an f-stop doesn’t relate to a doubling or halving of the value, but to the doubling/halving of the area coverage of a lens in relation to its focal length. And as such, to a multiplying or dividing by 1.41 (the square root of 2). For example, going from f/2.8 to f/4 is a decrease of 1 stop because 4 = 2.8 * 1.41. Changing from f/16 to f/11 is an increase of 1 stop because 11 = 16 / 1.41.
A wider aperture means that light proceeding from the foreground, subject, and background is entering at more oblique angles than the light entering less obliquely.
Consider that absolutely everything is bathed in light, therefore light bouncing off of anything is effectively omnidirectional. Your camera happens to be picking up a tiny portion of the light that’s bouncing off into infinity.
Now consider that the wider your iris/aperture, the more of that omnidirectional light you’re picking up:
When you have a very narrow iris you are eliminating a lot of oblique light. Whatever light enters, from whatever distance, enters moderately parallel as a whole. When you have a wide aperture, much more light is entering at a multitude of angles. Your lens can only focus the light from one depth – the foreground/background appear blurred because it cannot be focused on.

The great thing about stops is that they give us a way to directly compare shutter speed, aperture diameter, and ISO speed. This means that we can easily swap these three components about while keeping the overall exposure the same.

Note. All three of these measurements (aperture, shutter, iso) have full stops, half stops and third stops, but if you look at the numbers they aren’t always consistent. For example, a one third stop between ISO100 and ISO 200 would be ISO133, yet most cameras are marked at ISO125.
Third-stops are especially important as they’re the increment that most cameras use for their settings. These are just imaginary divisions in each stop.
From a practical standpoint manufacturers only standardize the full stops, meaning that while they try and stay somewhat consistent there is some rounding up going on between the smaller numbers.
Note that ND Filters directly modify the exposure triangle.

Joe Letteri on Production, VFX and storytelling
nerdist.com/article/joe-letteri-avatar-alita-battle-angel-james-cameron-martin-scorsese/
[Any] story [has to be] complete in itself. If there are gaps that you’re hoping will be filled in with visual effects, you’re likely to be disappointed. We can add ideas, we can help in whatever way that we can, but you want to make sure that when you read it, it reads well.
[Our responsibility as VFX artist] I think first and foremost [is] to engage the audience. Everything that we do has to be part of the audience wanting to sit there and watch that movie and see what happens next. And it’s a combination of things. It’s the drama of the characters. It’s maybe what you can do to a scene to make it compelling to look at, the realism that you might need to get people drawn into that moment. It could be any number of things, but it’s really about just making sure that you’re always in mind of how the audience is experiencing what they’re seeing.
