Code Review

This pull request correctly fixes a typo in random_contrast.py. The variable constrast_factor is now contrast_factor, and the method _adjust_constrast is now _adjust_contrast. These changes improve code readability and correctness. The fix is well-contained and I have no further suggestions.
