Hi there Bob
You answered my question.  We'll loose contrast and get grainy shots.  Seems 
the last time I developed old film the pictures were also rather on the red 
side too, if I remember correctly.  Anyway, like I 
said...........August....take some more pictures and get that old film out of 
the camera.  Oh, and find a way to share eh  :)
