Adjusting HDRI exposure level in Maya?

[sawasawa]

Hello. I have a scene where I take a simple plane and assign it a lambert material with an HDRI image(.HDR format) loaded in its color slot.

My problem is that although the image shows up when I render it with mental ray, the exposure is way overblown and I am not sure how adjust it.
Is there an "exposure" slider anywhere in Maya?

thanks

hey,
I haven't done it for a while, but I think you can just adjust the color gain in the color correction part of the image load node. theres also a way to control the photon energy when using global illumination, but I can't remember that one off hand. Oh by the way, you might have better luck creating a "surface shader" instead of a "lambert" that way the HDR image won't be affected by any lighting or shading in the shader in any way.
