Question

How to match a color between two photos

Hi All

First I apologize if this has been asked already, but i've exhausted all my thoughts on how to search for the question to find said answer.  If it has, I would welcome the direction to the answer.

I have two photographs that were taken underwater on two different cameras.  Both are in JPEG format, so I know that I cannot pull any data that would have been held in the RAW format.  They were both taken under the same conditions barring about 10 foot change in depth.

One photograph has already been color corrected.  The other photo has not.  Both photographs contain several colors that should be the same.  For example in the corrected photo a yellow shows up as R120 G142 B139 but in the uncorrected as R55 G150 B118.  An orange on the corrected is R200 G102 B73 and the uncorrected as R44 G111 B119

What I am looking to do is correct the uncorrected photograph so that the colors are more or less the same, using the histogram function or similar, so that I can then use that information to color correct a number of other photographs.

How would one go about this?

many thanks in advance

    I missed what Dave mentioned a out the 10 foot change in depth. That will make a lot of difference.

    I would agree with Chuck that curves may work however that extra 10 metres may make the red hard to correct - the blue and green values are close in both images, but there is much less red in the uncorrected image which I suspect is due to the red light falling off with depth. Using a curve to bring up the red from 44 to 200 is likely to lift up noise and artifacts with it. So your correction may be limited.

    I would suggest curves and place some eyedropper markers to show the corrections, as you're making them. Can you post the two photos?
