This works, but I bet it could benefit from a handy Numeric shortcut.
Anyone know how to make this more elegant using Numeric?

        array  = pygame.surfarray.array3d(pic)
        for i in range(len(array)):
            for j in range(len(array[i])):
                for k in range(3):
                    num = array[i][j][k] + adj[k]
                    if num < 0:
                        num = 0
                    elif num > 255:
                        num = 255
                    array[i][j][k] = num
        pygame.surfarray.blit_array(pic, array)
