now I want to copy the photo with Indigo.
distance of the television camera to the fund of the cube 68cm.
I don't know the lamp.

hmmm...
as the internal colour of that box is white, I guess, you used the wrong whitebalance for your cam: you used sunlight or equal energy, or such, but not "A" (lamp / indoor light / ...)

I guess, your tonemapping is way wrong...
the shadows are weaker, than the model ones...

paper has ~0.85 pure white, you know?

If you use wood, you also can use the correct colours :D
blue or green and red :D

And you may ask, which colour that would be EXACTLY, :D should be possible ;)

It looks quite nice and quite simmilar :D
just add a floor plane, to also get that light :D

ok :D
try to get the whitebalance of your cam correct, then :D
if it's still the same lightsource, you need "indoor" or "artifical light" or such a white balance...

my camera has it called "artifical light" ;)

Or simply set your WB in kelvins - looks like you're shooting ~3000 degree light (incadescent) and using a sunlight wb setting (~5600 k)

yes, auto-whitebalance would be a good idea, too.
