In the upper right, was the magazine photogram, it was F11 for 10 secs.  I got the white and grey because the magize was too transparent and there was not enough light which crated the white, and the grey was just enough to make a shadow but there was no balnce between. The second All black one was F11 for 10 seconds but there was too much light exposed to the photo paper, before and as doing the pictogram. The next one PUP  got the grey because there was the right amount of light and layering of the light, and the black was to much negative space but made the picture as a whole balanced. The last one with the trees, was all around perfect, it was F11 for 4seconds, there was the right amount of light, right amount of negative space, and layers between black white and grey.
