Corona EXR wont open in photoshop?

Hi, I want to save out my lightmixer passes in 32bit so i can do some linear comp in photoshop but i cant open the file. Has anyone got any ideas how i can do this? Do i still need to mess around in after effects to be able to do this?

Thanks
Jack

Nevermind, saving it as exr rather than dumping an exr worked.
