Grey scaling/Colored parts.

Open the image in Photoshop.

Duplicate it.

Now Take the top layer and set it to "Luminosity"

Now (still on the top layer) just erase where you want color the color to be.

And everything else will remain grey.

You cannot have part of a photograph "grayscale" without all of it grayscale. Maybe just a term, but important because if you change an RGB photograph to Grayscale you loose all color and many of the features of Photoshop do not work on grayscale images. Okay, that said, what you want to do is change parts to black and white and retain color in some location. How to do this follows:

Duplicate the photo and close the original. Create another layer by Layer %26gt; New Adjustment Layer and select Saturation/Hue. In the window or dialog box that opens, slide the Saturation slider all the way to the left. Your photo will be b/w in this layer. Click OK. You now have two layers, the background which is color and the adjustment layer. The adjustment layer has two icons, one for Sat/Hue and the other to the right. It is solid white. Click once in this white box. Change your colors to the default black and white. With black as the foreground color. Select the Brush tool. Paint the area of the photo you want to be in color. Set the Brush tool to size and softness that works best for the photo you have.

This is a mask. In a mask, black reveals the layer below it. White covers it. If you mess up a little with the black, switch to white and paint over your mess up. This is by far the easiest and best way to do what you wish.

If you wish to make the black and white layer a sepia tone, double click on the Saturation/Hue icon in the layer to reopen those adjustments. Click the box Colorize and move the Hue slider to the color you like best. Click OK when finished
