Negative and Positive

Differencess:
-The negative is opposite colors than the positive.
-The negative has objects on the opposite side than the postive.
-You can clearly see what exactly is there in the positive.

Because the negative paper is sensitive to light, if you put it close to another light sensitive paper, it will reverse the tones and makes a positive.
