meaning in the back of the photo Hi Someone tell me before, the number in the back of the photo you get back from the lab indicate the color and exposure correction they have made to fix your photo. Any one know what is the order mean e.g. +1 N -1 -20 Thanks.

They have to do with the different colors that are added or subtracted from the developing process. Any good developing station like Eckerds, or Wal-mart should be able to tell you...I will try to call my person and ask them... Try calling the local developers in the area, like Eckerds, Walgreens,etc... Good Luck, N

These numbers refer to machine prints. Normally that's how they're done. If you decide to make enlargements yourself on a hand enlarger, it won't look the same- there's no correlation. You just have to test out the print yourself- typically you'd want to figure out the settings on your enlarger yourself to figure out your starting point for printing. This is generally done shooting a grey card and bracketing, and then taking a densitometry reading off the neg of the grey card- then you print the shot with the right densitometry reading (set by the film manufacturer) and correct that print against the grey card. That will help you know when you're shooting in the wrong kind of light with the wrong type of film, and what kind of compensation you may have to make everytime you print a certain type of picture. But the numbers from machine prints are completely different. Sreedevi

Due to the impending weather problems down south here I have not called my local developer. However, if you call someone at your local developing "shop" then they might be able to explain them... I will work on this next week after hurricane lili...

Right- you want to know what they mean. In your example in the question you have +1 N -1 -20 they stand for four values: The N just means neutral- no change. Hope this helps.

Thank you for all your help, Naomi and SreedeviS. I really appreciate it. So in the example, that mean they increase 1 unit of magenta, decrease 1 unit of cyan, decrease 20 unit from the density (make it brighter) right?

Right. And yellow stays normal. If you found out on a hand enlarger what the normal settings were for that enlarger, theoretically you could do the math with these machine values and see if that works. But like my lab said, it doesn't work out. I try to compare with the negs now before doing a test print of something the lab did before me.
