Always a decision maker. What needs to be photoshoped and what can be left the way it is. I have attached an image that shows what can be done. Compare the two (before and after)

I have used a variety of different filters for this one, most importantly I have used a white neutralizer to give the wall and ceiling colors a more natural looks. I have enhanced the pattern of the floor with a tonal contrast filter and have opend up the room by using brilliance and warmth adjustments. You will also have noticed that wall switches and other things have been digitally removed.
