Importing OpenEXR Files

OpenEXR files have the ability to store high dynamic range images in 16-bit or 32-bit floating-point formats. Because of this high dynamic range, these images need to be handled in a specific way. You can import an OpenEXR image file and view it in Smoke the same as any other type of image file. But, in order to perform any image processing or compositing on the OpenEXR image file, you must apply a conversion to store it in a 12-bit, 10-bit, or 8-bit linear format on Autodesk storage.

You can convert OpenEXR image files using the LUT Editor to process which areas of the image that you want to highlight or preserve. See Colour Management with LUTs.

Alternatively, you can select the Resize option and set the Bit Depth to 8-, 10-, or 12-bit to affect a linear resizing on the OpenEXR image file. Note that with this method you have no control over which areas get highlighted or preserved.

To import an OpenEXR image file:

1. From the clip library, click Import Image.
2. From the Format box, select the OpenEXR image type.

   
   

3. Browse to the directory containing the media that you want to import.

   You can set a number of display and search options to help you find what you need. See Browsing the File System.

   NoteBy default, the file browser points to the images directory for the project.
4. Optional: Enable the Scan Subdirectories button to display all the subdirectories and their contents.
5. Select the image that you want to import.
6. In the File attributes area, ensure that the Bit Depth used in the OpenEXR image file is displayed.

   
   

7. Optional: Specify a previously-created LUT.

   
   

8. Optional: Perform any resizing operations.

   Adjusting the Bit Depth to anything other than 16-bit fp will cause a linear resizing to occur on the OpenEXR file, negating any of its dynamic qualities.

9. Enable Soft-Import if you want to import a reference to the media, but you do not want to store the media on the local storage.
10. Optional: Select a queueing option from the Add To Queue box.

    
    

    If you soft-import clips you can generate proxies in the background. This gives you the ability to assemble the timeline while proxy generation is taking place. See Importing and Soft-Importing in the Background.

11. Click Load.

    After you have imported the OpenEXR image, you can view it in its native resolution and bit depth.

12. To perform any image processing or compositing, you will need to convert it using the Lut Editor. See Colour Management with LUTs.
