Hi,
In the past I just rendered an image and things looked good. When viewed on another computer or web site the results were pretty different. I then read about gamma correction and am trying to utilize that. I have set the gamma correction in max's preferences to 2.2. also the bitmap is set to in at 2.2 and output is 1.0. In the material editor I have changed any maps to use a 2.2 gamma.
Now i am rendering with vray, and under color mapping i have selected reinhard as the type, changed the gamma to 2.2, and am lost as to the multiplier and burn value numbers. I have used all kinds of combinations with all kinds of results but they all have some degree of washout for the colors. If I use the default values of 1 and 1 the image is very washed out but when saved as a jpeg and opened in photoshop the colors are deeply saturated and borders on the surreal.I just cant figure out what I'm doing wrong- any ideas or feedback would be much appreciated.
Thanks

I've never really mucked around with the gamma settings in Max or Vray so I'm not really sure what the answer might be. Perhaps this page might shed some light on the subject though:

This is a complicated problem that is to do with how different monitors and media are effected by gamma At every studio Ive worked at there have been issues with monitor calibration etc. at Animal we had a DPS reality which is a calibrated broadcast monitor that all our shots were viewed on for consistency. I'm not sure what you have tried but if you mess with gamma settings you should only do it once. doing it in max and vray will result in some weird results. My advice would be to firstly calibrate your monitor using some sort of manual calibration page. like this (I just did a quick google so don't know if its good or not) [Link to www.stanstudio.com]

then.

Adjust the gamma in the vray render dialog to 2.2 but not in the max preferences or vice versa.

compensate for the extra brightness and lack of contrast by adjusting your light intensity and making changes to your materials (make them darker to compensate)

You can also mess with gamma in photoshop using levels or render to a high dynamic range format like openexr for more control.

Thanks all for the help, I'll try again but then I may just scrap it and continue without any gamma correction.
