How can I get white ceiling after a photo mode (.png format)?

Hi there,
When I put my drawing into a photo mode-after that a ceiling is getting a grey or dark.
Is it possible to set up a white ceiling and get it white in .png format?
Cheers

If you set the ceiling color to white, you'll get some white close to light sources and probably some light grey elsewhere. Try to increase the power or the number of light sources.

Hi,

if i do not want any color after a photo mode. Can we do this ?
or at last...a plain white or black color.

By "white or black", you mean only these two colors with no gray?
