OK I have been photographing stuff for about 5 years now but I have ran in to a problem recentley. My negatives have gone from perfect in the last three months to the last batch I developed being very grey. The problem is I dont know why. Since this problem started occuring I have started bracketing again. I have noticed that when my meter says it should be dead on its not. At +.5 it gets better and at +1 its still better but still on the gray side. Is thier something I am diong wrong?
