Hi there,

I don’t know what it is called, but I’ll try my best to describe it.
How is it done where, say a young lady, holds some flowers in her hands where the flowers are in full colour and the rest of the picture in B&W?
I will really appreciate your help.

Well, quickest way: Take a full colour image. Duplicate the image into a new layer. Make this new layer invisible. Desaturate the first layer (makes it black and white). Make the second layer visible again. Hit Q to go into quickmask. Paint over the area you want to remain in full colour. Come out of quickmask (press Q again) and you should now have the area you want to be selected. You need to inverse this selection so that we can delete everything in the current layer APART from the selection. Hit command+shift+i to inverse your selection. Press delete. You should now have a desturated base layer, with a full colour cut out of just the selected area visible…

Say, keep the original in RGB and select everything
but the flowers then select image>adjustments>channel mixer thick monochrome (or whatever: got the french version),
mix the channel to set the BW contrast and brightness,
click OK and the new channel mixer layer comes automatically with the mask made with the selection.
The bigger work is to select properly.
Once you have the mask you can apply filters to it as blur or noise. But as usual there is many other ways to do it….

An even easier way would be to drop the stage where you duplicate the image onto a new layer.
Just go into quick mask, paint in the area you want to remain colour. Then come back out of quick mask again. The area you painted should be deselected, and the area you didn’t paint should be selected. Now go to Image > Adjust > Desaturate, and the selected area will change to Black and white, leaving the unselected area colour.

Of course, if you want a bit more control over the conversion to black and white, you’d be better to use Channel Mixer instead of Desaturate.

If done right, you are looking at this sort of effect.

That would work great too, but if then you decided you’ve screwed up the effect you’ve lost the ability to fix it as you’ve edited the original (at least, until you reload). My technique, you could then go clean up the edges of your cut out or separately apply colouring & filters without having to remask etc all over again.

Excatly, thank you very much! I will start right away!

Or you could step back using the history pallette.

True, and if I’m really honest, your technique is the one I tend to use.

You can just call Colour & B&W and it just work wonder.

How is it done? not much difference than any basic technique to replace any part of the image. IOW, you just need to learn ONE technique then using the exact same technique on 1001 other creatives. And same thing

– Using multiple layers

– Using just the basic commands like Lasso, Eraser, Mask etc.. to mark and remove some part of the top layer to show part of the lower layer.

Here is an example that you may be able to have the picture.

1. Put a paper-bag over your head

2. Cut out the HOLES for eyes, nose, mouth then you will see your eyes, nose, and mouth. That’s what MASKing is about (a MASK).

History is a neat feature *but* just like the real history it only work with the original (non-modified) image.

I do Color & B&W quite often and I usually use Quick Mask.

That will work, but it’s far from the quickest way. You can do it in a third of the time.

Select the area that you want to be color. invert the selection. Choose Image->Adjust->Hue and Saturation. Move the Saturation slider to 0.

To modify SpaceGirl’s method, just make the the Selection a Layer Mask on the Dupe Layer. Save_As PSD (or choice with Layers), and you can always go back to adjust.

For the Desaturate/Channel Mixer, do it with an Adjustment Layer, so the original is always there.

…and you may either have so many ugly edge or spending more time to clean up the ugle edge. Or some quickie may be ok for displaying, but it may show all the bad technique on the print (or zoom in large enough).

Anyway, I have been replacing (pretty often) the background with digital background for many years, and I do for large print too so I am pretty good with this. Yes, I use Lasso too, but must be combination with layer and quick mask (and many diff. techniques).
