Cropping Images into Photoshop

[icu222much]

I'm cropping a bunch of photos into Photoshop from various sources. The light source and intensity are obviously different for each photo cropped into my collage, and as a result it looks really copied and pasted. I was thinking of manually dodging and burning the various images to make them look better but I am wondering if there is an easier way of doing this. I was reading to use the 'Match Colour' function, but that did not achieve the look I was looking for (or I was using it wrong).

Any suggestions will be appriciated.

You can adjust the brightness and contrast, or the Match Color function is great IF the two selected colors are to be exactly the same, and have a similar light balance. A dark image and a light image won't do well with color matching. Dodging and burning is not a good idea in this case, mess with the brightness, contrast, gamma, of the imges.
