not sure if this is what it is called, i am quite versed with photoshop, i have been trying to match an image, one side is much brighter than the other, faded images i just lowered the ammount of blue in the image but when the image is half faded and half perfect, i have tried curves and levels etc but there may be a better way if anyone can help thanx.
place each image in a layer. select the layer of the one you want to change. Go to menu Image->Adjustments->Match color. Play with the settings. Make sure you have the other layer as source reference. It's magical!
