Is there a way to change the white ballance after a photo is shot? I accidently shot all my pictures in the wrong white ballance so now everything is blue. Thanks

Sounds like you did not shoot on RAW :-( bummer. If not no you can't but you still may be able to save them with adjustments in PS.

Sometimes wrong white balance doesn't hurt, on contrary, makes it cooler. I sometimes intentionally set it wrong, like here:


Although for normal shots of course it's not cool.

And clean up works most of the time by tweaking levels in PS, mainly concentrating on decreasing amounts of blue, depending on how exactly you had it set wrong, as Thousands Fall said.

You could also try the Photo Filter adjustment in PS. QUick and dirty.
The Match Color under Adjustments and then hit the Neutralize button and adjust it...Maybe.
Best bet is probably using the Color Sampler tool and marking three areas...One that is suppose to be white, black and a neutral gray. Go to Levels and move the R,G,B sliders on the white and and black ends until they equal out (ie: whites are 250, 250, 250 and blacks 8, ,8 ,8) in the Info pallete. Save it (if it looks right) so you can load it later for the other pics in a Batch session.
Then go to curves and set a point on the first intersection line of the bottom left box and top right box in each of the R, G, B areas. Look a the info box, get out the calculator and add the 3 gray pooint numbers and divide by 3 to get the average. Go to each of the 3 colors. Click a point in the middle somewhere. In the input box place the original number showing in the info palette. In the output box put your averaged (and adjust up or down until the number is your average in the Info palette). Do this on the three colors until they are all the same at output as averaged. Save it also for the rest.
can make an action for it after and do all of them if shot in the same light.

Quick and dirty redo (2 minutes) of Yura's as an example. Touched it with a little hue adjustment also.
