# TDM projection workshop - JS notes ## Introduction Why use projection in performance? (ask them) - simulate a particular location or time period - create a partciular atmosphere - special effects - layering visuals - simply converying information Lets take a look at some examples of projection in performance from recent professional productions and see what kind of moves they are making here - the orchard (anyone want to take a stab at how this is being constructed?) - einsteins dreams - dear evan hansen - west side story ## Input * pre-recorded media (how do we get it on the projector?) * live-feed (how do we get this on the projectors and how is it different than pre-recorded media?) ## Projector capacities * ports - VGA, HDMI, USB, mini displayport, maybe even mirrordisplay? * throw distance is the distance between the projector and the image on the screen * Long Throw: Providing very large images, this type of throw is usually from projectors that are installed in the center of the ceiling in a large room. * Short Throw: Providing large images while reducing shadows and eye glare, this type of throw is usually seen from projectors either installed on the wall or the ceiling closer to the wall — anywhere that is close to where the image will be projected. Short-throw projection generally refers to a distance between 3 to 8 feet away from projector to screen. * Ultra-Short Throw: Virtually eliminates shadows and eye glare, this type of throw is seen from projectors installed on the wall, the ceiling nearer to a wall, or a table projecting downwards. Ultra-short throw projection refers to a distance between 0 to 4 feet away from projector to screen. * contrast ratio is the difference between light and dark on a screen expressed by a number. If you take the brightest white on a screen and the darkest black and compare the luminosity, you will get the contrast ratio. High contrast is great for projections to get a clear picture. * most improtant thing is BRIGHTNESS (measured in 'lumens') - the brighter the better ## Surfaces * Imagine farkas - can it be a screen? * walls to cielings to curtains to bedsheets to professional-grade material from Rosebrand * light-colored and reflective surfaces work best ## Recreating the moves
