Hopefully they will be able to shoot them on the camera test day. If not, you will have to schedule time to shoot them with the 1<sup>st<\/sup> AD on the shoot days. This will probably end up being a lunch time or at the end of an already busy day. It\u2019s not trivial though and they are necessary.<\/p>\n<p>&nbsp;<\/p>\n<h1>Shoot<\/h1>\n<p>I have a VFX doc that should be filled in for every shot. It contains standard info like lens data, set measurements for tracking, camera move notes, colour space, camera position, lighting diagrams, etc.<\/p>\n<p>I use Shotgun to hold all the data, a pre defined folder structure for the shoot data and a doc for the DIT to fill in.<\/p>\n<p>&nbsp;<\/p>\n<h2>Data to grab in VFX doc:<\/h2>\n<p>Shot Name \/ Slate name \/ Roll and Take number<\/p>\n<p>Camera data \u2013 camera type, lens, lens type, colour space recorded and presented to the monitor, filters etc<\/p>\n<p>Camera move \/ position info \u2013 measurements plus a drawing if necc<\/p>\n<p>Rough lighting diagram \u2013 These are quite useful as just a quick visual guide for lighters to have as ref. The don\u2019t have to be super detailed but I tend to do a side on and a top down one that just gives the basics \u2013 light position, type, gels, diffusers, distances and a rough idea of angle.<\/p>\n<p>White balance of the camera<\/p>\n<p>Any additional passes or notes<\/p>\n<p>&nbsp;<\/p>\n<h3>Data to grab in camera:<\/h3>\n<p>Macbeth chart &#8211;\u00a0 we use this to balance\/normalise the colours in the plate<\/p>\n<p>Grey ball<\/p>\n<p>Chrome Ball<\/p>\n<p>Black point measure<\/p>\n<p>Clean plate<\/p>\n<p>A shadow plate (if there is a contact point \u2013 hold up a flag across the shadowed area creating a shadow on the floor)<\/p>\n<p>Lens grids<\/p>\n<p>Additional passes<\/p>\n<p>&nbsp;<\/p>\n<h3>Data to grab on a stills camera:<\/h3>\n<p>HDR<\/p>\n<p>Put a Macbeth chart in it somewhere. It helps with the plate neutral workflow.<\/p>\n<p>Set the White balance of the camera to the white balance of the shooting camera.<\/p>\n<p>I normally do 9 exposures and 6 directions\u2026<\/p>\n<p>&nbsp;<\/p>\n<p>Photogrammetry<\/p>\n<p>Camera position and any other relevant objects<\/p>\n<p>Lidar scans\/Photogrammetry of set \u2013 Take lots of stills of what the camera is seeing from all sorts of different angles. We don\u2019t tend to need the camera or the tripod in them but a few wider ones are fine. If there is an object in the frame that is useful for tracking make sure to photograph it from multiple angles.<\/p>\n<p>Reference photos of everything<\/p>\n<p>There might be some puppeteering, tracking markers, etc. \u2013 This is where you have to evaluate each shot as it comes along.<\/p>\n<p>&nbsp;<\/p>\n<p>Try thinking from back to front how a shot might be constructed in Nuke or what info you would need if you were constructing it in 3D.<\/p>\n<p>It sometimes becomes a bit of a balance between how much time you have and what you need. It&#8217;s important to get all the info you need but without delaying the shoot. Get in there and get stuck in, take whatever time you need and whatever time you can but sometimes they will just have to shoot!<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><b>\u00a0<\/b><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is some general info on what to collect from the set.
