LWF, Gamma, Exposure?

[deneb26]

hi there

i have a problem in saving out frames for an animation.
We are on Vray 1.47.03 and using the Vray VFB.
When i adjust the Exposure or Curve and want to save the Pic manually,
the resulting Picture is washed out if viewed with ACDSEE or Photoshop.
But when saving the Frames through the Max Common Dialog, the saved Pics
are very Dark and the Exposure-Correction is not applied.
What am I doing wrong here?
The Gamma in Max is set to 2.2 , the Input Gamma for textures, too.

as long as the mfb goes, even if you have gamma correction enabled, max won't save your images with it applied. it will display them corrected, but you'll have to manually override the system default gamma when saving them.

on the other hand, the vfb should work just fine. if you gamma correct an image, it should save it corrected.

You just need to save as .EXR. It will save them with sRGB profile and when opening in PS CS2, they appear just as they do in the MFB.

thanks guys

i thought it was a simple thing, that just wouldn't come to my mind.
okey i'll try it with the exr-export.
thanks so far.

Clifton,
Is there a way to save as exr without sRGB profile?
Thanks

You mean save as .EXR without having Gamma correction applied? Yes, save it as a jpeg

In a way its not really "applied" at least as I understand it, i.e. not "burned" in. Because .EXR is a 32-bit full-float image format, you should be able to remove the sRGB with the Gamma slider in photoshop CS2, or likewise in some other app.

I'm no expert on the technical aspects of the .EXR format, I just know that when saved as such, the gamma correction is there when I open it in photoshop, and as long as I haven't clamped the image, I can tweak the exposure in a realistic fashion.
