results from my pressure plate experiments

     Hi everyone,
     
     I have been fighting with this pressure plate issue on my Pentax 
     K-1000. The shadows from the dimples make my models look like they 
     have chicken pox.
     
     I came up with an idea and gave it a whirl. I have been shooting in 
     the dark using a couple of sheets of e-6 material in my flash filter 
     slot and that works pretty well ( thanks Mr. Davidhazy ). So I thought 
     up putting a piece of it between the film and the pressure plate. I 
     taped it to the camera just out side the film rails on one side so 
     that it is a flap setup and then load my film and shoot away. 
     
     That seems to have reduced the dimpling by about 95-99 per cent. I 
     seem to get more dimpling from shiny backgrounds than duller ones, but 
     even still I only have a hand full of dark spots instead of chicken 
     pox. 
     
     I suspect that if I move the flash off the camera, I can reduce or 
     eliminate the remainder.
     
     Tony
