Old image problem

[wmchauncey]

Circa 2008, before I had a clue what was happening behind the camera.
I have several images of different scenes/different sunlight, with different camera settings (ISO, SS, f/stop).

Within LR...is there an easy way to balance the colors between images?
Failing that...how might in be done in PS 2015?

really just try to find something in the image that is 'neutral', use the grey dropper, adjust to taste and in LR (or ACR), and then synchronize the WB/color settings.

That said, should a nice neutral grey shot in late afternoon really 'be grey' ?  You'd end up w/ a over-compensated image that is quite cold.  There's a lot of artist's prerogative in there.
