Hi,
do you change the gamma value (2.2 standard) or not....
in TG classic I always changed the gamma to about 1,5 (good for me)
I experiment with it in some scenes. I usually set it to anything between 2.0 and 2.2, very rarely below 2.
You just have to figure out what looks best per scene.
Regards,
Frank
I find it better to render and save out to EXR and adjust gamma, exposure, etc. dynamically, or even tone map.

I second that, render to exr and you can do all kind of that color/brighntess/contrast manipulation without destroying the picture.
I think I had some problems with EXR and Photoshop, I had more banding than in the BMP saved render.
Anyway, even if I do two renders a year (::)), as in TG classic I usually set gamma to a low value.
what does render to exr mean ???
EXR is a file format.
It is used for HDR images: http://en.wikipedia.org/wiki/OpenEXR
Saving to EXR will allow you to store much more color information than in BMP, provided you have an image processing software that can open it.
how do I get such high images ???
resumme: you render and save it by default... then you change the contrast, etc in a graphics programm , correct ??
Depends on what you are planning to do.
To actually view or print your image on a standard monitor/printer you have to convert it to a format with 8 bit color depth per channel (HDR is 16 bit). To do this you use a graphics program (like Photoshop). Typically you would use tone mapping to map the 65535 color values per channel to 255 per channel.
Wonderful and very qualified answer.... top !!!! thanks !!
After you render, when you go to save the image, there is an option to choose the format. Simply change it to EXR. You will need a program that can open and adjust it properly. Photoshop works well, XNView will open and do some basic manipulations, there are many others.
