urgent:make a black and white image for folio

hey everyone,

i've been so stressed on the last days doing my portfolio!!! so, everytime i come across a new difficulty i feel likely having a breakdown

so i really hope you can help me, my question is: can i render an image in black and white using AutoCAD 2008? or the black and white is from photoshop? it may sound silly, but i found that black and white rendered images have a stronger appeal in a portfolio. i posted some images below but they're not mine, i randomly selected them in google images, so you could see which type of images i am talking about.

eagerly waiting for a answer...

I don't see why it couldn't be done.
