Hi, The only explanation for this "strange" behavior is (in my opinion) that the paper was at different distance from the pinhole. The first one was so close that the whole image was captured. The second one, was perhaps, well behind and only a portion of the image got the paper (and surely, the image is bigger than the first one). I hope this helps. Regards, Marcelo
