Photograms negative

In the first picture are my failed attempts/not final photograms. The test strip with the soldier, was my first attempt in making a test strip negative. The larger piece of paper that came out completely black, was a failed attempt in making a negative, too much light touched the paper. Leading to it to develop completely black. The second larger paper was my first attempt in making an abstract photogram. After developing it, I realized that not everything was showing up, so I needed to build up and add more layers to my photogram.

In the second photo, are my final negative photograms. The first picture is my landscape photogram, with the sky and the clouds as the background, the mountains as the middle ground, and the soldiers and ground as the foreground. The second photo is my symmetrical photogram. I had to add tissue paper and a couple layers of netting for it to actually show up after being developed.  My last photo is my abstract photogram, at first I didn't have enough, and there was too much negative spacing. Then I added on more and layered more objects on. I added a few pieces of tissue paper and and couple layers of netting. Without doing that, none of the netting would've shown up.
