skimage.io.imsave "destroys" grayscale image?

I have an array of graysale image read in from a color one. If I use matplotlib to imshow the grayscale image, it looks just fine. But when I io.imsave it, it's ruined (by an outrageous amount of noise). However, if I numpy.around it first before io.imsave-ing, then it's significantly better, but black and white are still all swapped (dark regions appear white, and bright regions appear dark)

scipy.misc.imsave, on the other hand, works perfectly.

Thank you.

I think I've figured out why. By convention, floats in skimage are supposed to be in the range [0, 1].
