178 PICTURING MIRACLES 



on two or three buds that have been carefully placed; 

 these buds are then matched up in the laboratory 

 with the lapse-time camera and open as though it 

 were one continuous picture. There is a motor that 

 drives the carriage at any speed and another that 

 runs the camera at standard speed. It means bat- 

 teries are required to run the motors, and it takes 

 about an hour to set up the outfit, take the picture 

 and pack up again. The picture is stereoscopic and 

 in natural color on the screen as it shows three sides 

 of the same object as it passes it and the subject is at 

 a shorter distance from the camera than the back- 

 ground, which is changing all the time so it stands 

 out in relief, and has the advantage of showing sub- 

 jects in their natural habitat and in the same picture 

 a few seconds later a close up of them without any 

 sudden change of location. The entire outfit, made 

 in my shop, fastens on the side of the car and every- 

 thing about it was designed to set up and knock 

 down as easily and quickly as possible. The hour's 

 extra work is well worth the effort.
