Another way of getting grain is turning up the sensitivity while lowering the exposure to compensate..
Of course that results in digital noise, which is not visually equivalent but is an artifact of your actual medium.
If you don't like the digital look, you can still use this method, but develop the image twice, one timein monochrome with contrast and brightness in mind.. Then another photo with color and saturation in mind..
Then you cheat and do a Gaussian blur on the color photo that is strong enough that the digital noise diminishes to an acceptable level.. then you overlay the blurred color image on top of the sharp black/white image with saturation from the color image being used.
This is a hack, and can also be used if you shot some color picture in adverse conditions and want both colors and sharpness.
