@ Agent 0013, We only allow .jpg uploads anywhere in Renderosity...some folks save as .bmp for post working as it's a lossless format and the after post work save as .jpg for uploading here.

re: the saturation thing , yes, and PhotoShop and many of the 2D apps allow for adjustment of this if you don't wish to rerender the pic...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
