Opening EXR Files
Exr-IO offers a variety of options when opening OpenEXR files.
To open an OpenExr file in Photoshop using Exr-IO, you can use three methods:
Open (Ctrl+O) or Drag&Drop
The most common was is the default “Open” image or Drag&Drop in Photoshop will open the OpenExr files with Exr-IO Plugin.
Open As (Alt+Shift+Crtl+O)
In case you have installed in Photoshop other OpenEXR Plugins, it may happen that they get prioritized in the image opening process and take over the import process instead of Exr-IO plugin. It is recommended to uninstall the other plugins or force Photoshop to explicitelly open the desired file using exclusivly Exr-IO. To do this, use “File/Open As…” and pick explicitely the “Exr-IO” as extension, in order to open the file with Exr-IO.
Exr-IO Options Widget
After opening an OpenExr file, you will see prompt the Exr-IO Options Widget. This indicates that Exr-IO is both correctly installed and able to interprete the image.
