ColorShare – Usage

ColorShare for Android

 

USAGE

With the onset on Digital Acquisition systems not everyone can afford an onset colourist or Post facility Colorist to process and grade each take for editorial dailies. More often than not your dailies will be processed as a “1 lite” using typically 2 – 3 different Luts.  If you have the luxury of having graded dailies Color Share can still work for you in communicating the color intent of a scene to the colourist or Director.

Outlined below are some of the ways you can introduce Color Share into your color and rushes pipeline. Click on an option below to learn more.

 

1 Lite Dailies

Acquisition – Raw / LogC Prores / LogC DNXHD

Camera Dept Monitoring with production Rec709 monitoring LUT.

In this “Indie” scenario where graded Rushes don’t fit within the budget and you’re not shooting on a sound stage you’re also going to end up with a number of sequences in the edit that are a little bumpy. Time and natural light constraints can also factor when day light is quickly disappearing and all you want to do is have peace of mind that a shot is easily salvageable, knowing that on the rushes its going to look a little under or over cooked.

In this scenario save stills to your camera (Alexa allows you to save LogC Jpeg stills while you’re shooting) and have them transferred to your android when the Mags are turned over to your DIT .

COLOR SHARE

    • Import the relevant stills into Color Share and Select and Activate the same production 3DLUT as used onset.
    • When Assessing exposure use the “printerLight / RGB exposure ” tools first.

If in doubt you can send the Stills and the CDL’s to your colourist. They can assess for you and possibly suggest some alternate color timings.

NOTE : Make sure ASC CDL mode is activated in the Preferences. This will ensure all the other functions such as Texture overlay and Vignettes are de-activated.

 

Graded Dailies

In this scenario Color Share can be used to create CDL’s or BLG’s to send to the rushes colourist as a true color representation guide of the preferred color intent of a scene or setup.  The colourist can then use this reference to balance the surrounding shots. Loading a CDL into Color Grading Applications is pretty trivial these days. Unlike sending a LUT a CDL is loaded as an adjustable Color Grade meaning it can be tweaked depending on the surrounding shots.

Alternately the colourist can receive stills remotely and grade and pass on CDL’s or BLG’s to the DIT to use for the processing of editorial rushes .

Color Share

    • Import the captured LogC stills into color share
    • Apply the production LogC2Rec709 Lookup Table.
    • Send Cdl’s and reference baked color Image to Colorist or DIT.

Email Colorist the ShootDay Folder Container containing the days reference grades. As the cdl’s have the same name as the reference camera clip most systems can automate a cdl / clip name match.

Alternately you could upload the files to Google Drive or any other cloud based storage for shared access.

NOTE : Make sure ASC CDL mode is activated in the Preferences. This will ensure all the other functions such as Texture overlay and Vignettes are de-activated.

 

 

Zipping Files and Sending

Sending Folders of Still and CDL’s is easy.

Download a program off google play such as “ASTRO File Manager”. Its Free.  Other options below.

Navigate to the ‘ShootDay’ Folder that you have created your Stills in. They will reside in

/SDCard/colorShare/save/yourProjectName/

Within the application find the “zip” option. With the folder highlighted select ‘zip’. Its now ready to email from your preferred email host.

Alternate File Manager options with the ability to Zip Files and or Folders include:

AndroZip Free File Manager

ES File Explorer
