hi,
i have recently started to get into infrared film.  i have been using the 
kodak b/w.  it seems that on every frame i get plus density at the top 
and bottom.  the data sheet warns against using plastic reels and tanks, 
so i use metal.  i can't think of another cause.  i also have been 
getting numerous pinholes throughout the roll of film. they are tiny 
spots where the film is clear.  however they are not like normal 
pinholes.  these seem to have a more diffuse edge.  
i love the effect of the ir film but these technical problems are getting 
me down.  can anyone help me solve them?
thanks
