Smile gnomon workshop interior scene lesson3

hi , i was studying the gnomon workshop video tutorials using v-ray (interiro illumination) video tutorials..

sorry i am little new in v-ray but i just have a question if anyone can help ,

i noticed that we have to use gamma correction before rendering if we want to save the rendered image as tiff 8bit ...

but what about if i want to save the image as jpeg? do i have to use gamma correction in this case, or i can leave it at linear (default)

thanks ...

Hi

The gamma correction needs to be applied regardless of the format you wish to save the image in.

yes through color mapping I typically use exponential under the color mapping

if you are new to vray http://www.vray-materials.de/forum/index.php has some good information and can ask vray specific questions. It helped me when I started out in vray a least seeing how other people did their materials.

oh - yes - before rendering

use the preview option under the Exposure control tab to render a small preview - the great thing is that it is interactive - once rendered you can adjust the settings and immediatly see the effect
