Use a luminosity mask, or use the threshold adjustment to make a mask of just the blacks in your image. Or you could just use a Hue/Sat layer and use the "Blend If" sliders under blending options to restrict the adjustment to the blacks.

Re: is there a way to "desaturate" the black ?

I'd use the blend if sliders (luminance blending), as they're quicker and allow more flexibility imho.

Another simple idea would be to add a Selective Color adj. layer, set it to "Color" mode, go to the Blacks and add Black to them (that way the black will be 100% and therefore have no color. Applied in "Color" mode it'll desaturate the blacks).
But I suppose MacBurg's idea is better for this kind of tweak :-)!

Re: is there a way to "desaturate" the black ?

What is the issue? selecting the Blacks only or what to do with BLACKS?

You need to put the blacks, only the blacks, on a sprate layer, on the very top. Find a way to do so, if you need help on how to select just the blacks, let us know.

Once the blacks on a separate layer, on the very top, create a selective color adjustment layer, just click that half black half white circle on the bottom of the layer palate, this will create new layer on top of the blacks, this layer will have selective color adjustment in it.

Now, before you do any thing, look at the selective color window (it is realy tap), anyway, on the bottom of this selective window, there are few icons, click the 3ed one from left, it is the "clipping" icon, basically, it limits whatever you do there to just the lyer under it, which in your case, the blacks layer

you see where it say "colors", click the down arrow and select "neutrals", on the blacks slider, move the triangle to the left, this will lower the intensity of blacks, play around with the other colors, this will change black to something else.

If you have a problem or do not understand any step, just let us know.

(this is not blend if or luminocity mask)

It's not clear what result you are after. Are you trying to increase detail in the blacks, fog them to gray or make them neutral in color? What color/density are they now?

whatever way you select them, there is no right or wrong way as long as they are selected and paced on a separate layer. The blacks might be contaminated, just erase other colors off that layer this way you are left only with blacks (a better way will be to mask off other colors, but for now, just erase any thing you don't like and leave only blacks)

Re: is there a way to "desaturate" the black ?

Use the magic wand, set tolerance to low so that you can select only blacks, once you do your first selection, press and hold the shift key while selecting other black areas, this will add them all up into one big black selection, keep clicking till you have one solid black area selected. Once satisfied with your selection, hit Ctrl+J to duplicate layer. or just go to edit\copy , then, edit paste, this will place the selection on new layer
