That strip along the left edge is "edge print" which tells the type of film it is along with other identifying data. That was exposed on the film at the factory before being shipped out for sale. During exposure in the user's camera, anything spilling onto that edge from the scene being filmed becomes a double-exposure with the edge print. There's no "behind" when you double-expose film. The light falling on the film is cumulative, whether it's in the normal image area or in the edge print area. A double-exposure is the same no matter where it happens on a piece of film. The images are mixed together. Only an exposure to almost white or fully white would keep any other image from possibly appearing. In other words, if enough light from any exposure blows out all further ability to show detail, no other exposures will create an image - the film has accepted all the light it can for that spot on the film. Each exposure makes the spot on the film whiter/lighter until it can't change any more. There are some slight oddities in the way the edge print appears on that film compared to the few thousand feet of 8mm Kodachrome film I own going back in time much before 1963. Possibly the most important one is that none of my Kodachrome film (which was developed by Kodak, of course, and most if not all in Dallas) has any edge print from processing to show the plant location (such as "D" for Dallas as Zavada claims was done). I hope that helps clear some of this up for you. ----------------------------------------------------- Greg, let me know if I can add anything more. I haven't rec'd any email notices of replies here on the forum before even though I tried to set my preferences to send them.

Thanks for sending me a link to this thread, Greg. And thanks, Don, for the mention. It's good to hear from you and that you're still active in this. I'm still around and doing work little by little. Greg and I were doing a few things in November and I'm working a little with Mark Oakes now helping him with something. Scott

I have lived just outside Dallas all my life and have been researching the JFK assassination for about 35 years. My work is in electronics. I repair circuit boards which are used in machines which test electronic parts. I also do a little design work as I have time to do so. Most of my research into the assassination has been with the photographic evidence and primarily the motion picture evidence. But I have also thoroughly studied the other aspects of the case to have a broad knowledge of the case.
