how to use a binary mask as a "stencil" for a grayscale image?

Hey everyone,
I have a binary mask (first attached image) that I want to use to trace-out the image of a gray-scale picture (second attacked image) and create another image in that manner.
I tried the simple AND operation, but the newly created image is a binary, not grayscale. I want to use the mask to crop out the image, without changing anything else.
Thanks in advance for any tips!

Simply use the inverse of the mask to set those pixels to zero.
imageCopy = grayImage; % Make a copy so you don't destroy the original.
imageCopy(~mask) = 0; % Set black areas to black, leaving gray areas intact.
