Note: You might get a false positive report for the installer from McAfee.  McAfee has some known issues with their heuristics when using an NSIS Installer. You can safely use the installer. Hopefully this confusion will be cleared soon.  It seems that the portable version is unaffected by this issue.

Plug-ins for RIOT

Even if RIOT is available as plug-in for other programs like IrfanView or GIMP,  RIOT itself can be extended with plug-ins to enhance it’s functionality.

Currently only input plug-ins are supported. In the future I hope more plug-in types will be added.

Download the RAW + HDR plugin package – allows you to open HDR, OpenEXR and RAW camera images

Special notice to IrfanView users
IrfanView has bundled into the plugin collection the Lite version of the RIOT plugin.

Here you can find the extended version (also FREE)  that goes beyond Lite version offering extended functionality.

I always recommend the extended version over the Lite one.
