Color Share – Overview


ColorShare for Android



Color Share is a powerful Non-Destructive Image and Photo editing and color enhancement tool.
Easy to use, start with the numerous presets or craft and save your own color adjustments from scratch. All color adjustment and image manipulation functions are constantly live.

Use Color Share’s unique meta share to share creative color intent between creatives such as cinematographers, colourists, and your DIT. Share Color Grading looks to Digital Grading Systems such as Baselight, Resolve and Mistika.

iRiS Stereoscopic Base and Disparity Calculator – 1.1.0 Update – Introducing the Roundness Factor

The Stereoscopic Base and Disparity Calculator 1.1.0 for the Android OS has just been updated and introduces a new base calculation measured around the perceived on-screen Roundness or depth of an image.

The new option allows the user to either :

  • Calculate the camera base separation using a predetermined target parallax amount
  • Calculate the camera base separation to a “Roundness Factor” of 1.0.

The Roundness Factor represents the factorial difference in depth between the photographed scene and the resultant projected 3D scene.

It is generally referred as a factor because ideally one would want to capture and project the same depth representation of photographed object, thus having a factor of 1.0.    IE: Physical scene depth/perceived 3D on-screen depth.

If the Roundness Factor is less than 1.0 then for example a round sphere will appear flat and compressed. It will have lost is dimensionality.

If the Roundness Factor is greater than 1.0 then the same sphere will appear stretched or extruded on the Z depth plane.

Consider dimensionality in filming the close-up of someones strong angular face. Captured with perfect roundness the 3D on-screen projected face will feel volumetric and proportionately correct. If the “Roundness Factor” starts getting too high the persons head and nose will begin to feel stretched toward the viewer, which is not such a flattering look.  In this sense it is better to err on the side of a factor less than 1.0.

The effect of Roundness is related very closely to Lens selection. A longer focal length lens will have a much greater impact on roundness and Parallax as the base separation in altered. On a 75mm Lens it takes only small changes in Base distance to make quite large differences in background parallax and therefor depth.   Additionally sensor size is quite an important factor to consider as the resulting 35mm Lens equivalents could be a lot higher than you think.

As always it is recommended to test Lens/Sensor configs as much as possible before entering any project.

    DLux software update

    Update and Progress – Dlux Onset monitoring software.

    Recently I’ve been quitely buying and studying books on Cocoa programming and OpenGL programming to give the Dlux application more functionality.

    Recently added:

    - added ASC Color Correction and ASC saturation parameters

    - Improved Output of XML and Imaging data to include ASC color SOP data together with 3DLut information.

    - Improving handling of Raw Cannon and Nikon DSLR images (intended for film jobs where DOP can send stills of graded DSLR with grading info to rushes facility. 

    - Improved handling of Live HDSDI video streams and Live Firewire HD Streams. 

    - New release date scheduled for before IBC.

    - Improved UI updating when recalling saved presets.

    - integrating Full Screen Mode for single or double screen use with external monitor.

    iRiS-LiveLut – Mac OSX – application update

    An update on my OSX software ‘LiveLut’ which had some major coding breakthroughs over the last week.

    Over the last few days I have successfully implemented the following features:

    3DLut and color correction 25 fps ‘realtime’ previews to :


    - Stills


    - Quicktime Movies


    -and Live incoming Video. (excuse the dodgy iSight camera)

    All on a Mac Book Pro.

    It still needs a bit of love on the UI side of things although that should not take too long.

    I also added a live data view showing the associations between Density, Code Values and Printer Lights from the ‘exposure’ based color changes.

    And the ability to save reference stills. (some time in the future i’ll incorporate the ASC color data translation ;)

    The initial release of the software will be a simple pared back version available for film-makers to reference when making Photochemical timing adjustments to Answer Prints. The second version will incorporate the Slope Offset and Power Color tools for reviewing Quicktimes with a 3Dlut applied. The third release of the software will enable on set previews of live images direct from the source. The out put can be tapped to an external DVI or HDMI enabled monitor. 

    User 3DLuts can be made and loaded into the program.
