Final test and finishing touches

Now that we had a system that produced an image bright enough to be filmed, it was time to do just that. I took the box round to Dan Duran's house as he owns the Sony EX1 Camera we would be using for the actual shoot on the weekend. We set up the filmable pinhole camera in the front room at night and soon realised creating enough light to replicate the daylight situation we would be filming in would be hard. So instead I borrowed Dan's light box and placed an X using black gaffa tape on the middle of it so as to be able to clearly see a focus mark. I then set about moving the light box with the X on backwards and forwards to get a better understanding of the depth of field and focal length of the lens. Form this test it became very clear the distance between the EX1 and the image plane would need to be around about four feet. This I believe was due to the low light situation and the need to zoom the image slightly for framing. Whilst the box was at Dan's he kindly sprayed the inside black so as to reduce the amount of light bouncing around inside. We also found time somehow to smarten it up for the imminent shoot date on Sunday at Chinnor Steam Railway. To do this we coated the now tatty outside of the box with white card and decorated the hole around the lens with a flaming trim.
