Photoshop Expert Required

These are publicity pictures for he most recent king lear production, the project aim is to change the colouring of each photo and balance the colour so the photographs are then more neutral. some are far too warm (orange) they need to match the colour and atmosphere of the film, with some being made a little more 'moodier', by touching up the contrast on some of the bluer ones.

I think all of this can be changed by using photoshop
