Andrew thanks, my 1st images were a lot bit "softer" . I very carefully blew out dust from inside camera and the pinhole itself and the next few rolls were significantly sharper. I also noticed that If I took my camera from inside (air conditioned) to outside hot and humid the images were quite softer (now I leave the Zeros in cases in the Land Rover ). Lastly, all of the film is pretty much processed semi-stand , which I think helps . The contact prints are smoother than the scans which accentuates the granularity of the pyro negs. Of course I believe the magic is in the purity of the hole .... Anyway, I really like the pinhole image for the strong emotional impact of soft smooth tonality and dimensional depth.
