Black electronic (automatic exposure) 
White window blinds (automatic exposure)
The used a black electronic for the black and a white certain blinds. What made pictures similar is how gray they are compared to the objects in real life.
Black electronic (adjusted exposure) 
White window blinds (adjusted exposure)
In these I adjusted the camera meter on my camera-phone for the images can look black/white. I tried to make them as close to the tone as I can while keeping the textures.
Good work.
