Irfanview display of exr differs from photoshop, mplay

[Deborah]

I have an exr digitally rendered image that displays in photoshop with bright highlights, however it displays in irfanview very dull. I can understand loss of data due to conversion but this is exactly the same file being displayed by photoshop and irfanview. Attached is a screen shot of what I am seeing. Any ideas why this is happening?

This sample file looks OK.

I recommend using a proper photo-editor to open High Dynamic Range images. the plugin only has one setting as far as I know, which may not work for all images.
