My negative and positive pinhole camera pictures were achieved by taking an image with the pinhole camera, then continuing to go through the steps of creating the negative and positive images.

step1: make the image visible, you do this with the help of the developer. I placed the image into the developer waiting 60 seconds until the image appeared visible.

step 2: stopping the chemicals,  this step lasts about 30 seconds, and stops the developer from continuing to make the image visible. 

step 3: Make the photo insensitive to light, after creating your positive you place the positive face up on the enlarger then place another paper, with the shiny side down, close the enlarger, and turned on the light for 6.5 seconds, then went through the same steps for the negative.
