Printing after making corrections with...

Hello,



I need some direction .. and hope that someone will help :) ..



Am making my corrections on my photos with Lightroom and anything I can't do in Lightroom .. I do in Photoshop .. however, when I print (please note .. I OUTLAB my prints) .. when I get my photos back .. they look nothing like the ones I have corrected in Lightroom i.e. too dark, etc. .. I do export them and am choosing the correct photo .. but they are not matching up with what I am sending out for printing.



Any suggestions? .. do I convert to home printing .. if so, any suggestions on printers? .. I'm new to digital .. I shoot with a Nikon D80 and a SB800 ..



Would appreciate any %26amp; all suggestions %26amp; help that you can give me.



Also, for those of you who outlab your photos .. any recommendations for good labs?



Many thanks in advance,



Brenda
