In photoshop, how do you make a photo greyscale, but allow one color to stay the same?

i want to do this with one of my photos and i'm not sure what its called. maybe filtered greyscale? but i know some feature on photoshop allows you to make a picture black and white, but still allow one color. for example, making everything in a picture black and white except a blue shirt and blue eyes. how do i do this?

Hey Hannah,

You could also make the entire image greyscale and re-color the image wherever you would like color by following these steps.... http://www.helium.com/tm/417887/change-c...

Or you could select whatever you wanted to make greyscale using the selection tools and go to Image %26gt;%26gt; Adjustments %26gt;%26gt; Desaturate

you have to duplicate the image. change on of them to grayscale, then combine them by placing the grayscale image on top, and erase the gray object you want to be color.
I don't know
