Photography Question 

Maria Khatri
 

Black and White with Splash of Color


I have CS4 and I cannot figure out how to convert a color image into B&W and then add color into selected areas of the image .. Can someone please help!!!?

I have found many articles that give tips but I still cannot achieve what I am trying to do. What is the best way to achieve this? I have tried the Desaturate and then go over with History brush but it does not look as clean. Thank You !

"but it does not look as clean."

As clean as what, Maria? Can you post the offending pic? That might tell u more.

  Maria, you are asking about selective coloring. One way to do that would be by layering 2 images. Make a duplicate of the original color image and then take the same image and convert it to b&w. Layer the photos, depending on how much color or b&w areas, layer one image on top of the other. You can use the history brush to bring back color to the areas you want. Another way is to use the eraser tool to erase those areas you want to be in color or b&w. Of course it would be easier to explain of we could see the photo you mention.

  Maria,
This comes up periodically and you may find more information by searching the forum. Here's part of a reply I made on another thread in October...These are steps to make parts of your image colorized. The same thread has two other versions.

---
1. Open the image and save by another name (effectively makes sure you are working on a duplicate of the original).
2. Set the foreground color to 50% gray. Just click the foreground color swatch in the toolbar, and set HSB values to H:0, S:0, B:50.
3. Create a new layer (Layer>New>Layer), and fill with the foreground color (created in the previous step) Edit>Fill, and choose Foreground as the Source. The image will turn gray.
4. Set the layer mode for the gray layer to Color. To do this open the Layers palette (Window>Layers), click Normal and choose Color from the list that pops up. The image will turn grayscale because you are applying gray as a color to the whole image. Now you are all set to make the effect happen by letting the color come through the gray.
5. Remove gray over the area where you want the color to come through. To do this, choose the Eraser tool (press E) and erase the areas of gray in your layer where you want color to come through. If you make a mistake, switch to the Brush tool (press B) and paint the gray back in.

The advantage here: no masking. This can work on multiple layers, requires very simple concepts, simple shortcuts, and simple tools. Menus may be somewhat different in different versions of Photoshop and Elements.

This is not going to make a conversion exactly like desaturating, which is the most rudimentary B&W conversion. There is potentially quite a lot to converting to B&W and getting the most out of any image. My favorite conversion is done using Calculations in a layer setup, that starts with the response I made here in yet another thread...

You can channel mix in Elements just as well as Photoshop -- you just need to know how. For example...Find your Green channel without using a channels palette (green is often a good black-and-white representation):

1. Create a Levels adjustment at the top of your layer stack.

2. Choose the RED channel from the drop list and move the white OUTPUT slider all the way left. (This will suck out the red.)

3. Choose the BLUE channel from the channels drop list and move the white OUTPUT slider all the way left. (This will suck out the blue -- and you are left with green.)

4.Open a Hue/Saturation layer, choose Green from the Channels drop list and move the Lightness slider all the way right.

This kind of separation can be done in any version of Elements. If you make the separations for each channel, you can mix them in even more exciting ways than channel mixer allows as it is a solid but limited tool.

I make add-ons that simplify the process of making separations to a click -- you can find them on my website (Elements Website)...there are free sets for each version up to Elements 7.

The conversion to black-and-white is going to make all the difference, and you can see how even that can become pretty complicated. Better results often are ;-)

  Thank You everyone for your advise! I will try them.

I am new to this and I am so glad I asked .. I have spent hours googling and a few suggestions but nothing worked-

What I mean by the image "is not as clean" is after I have completed the areas I want in color .. there are areas I went over that should remain b&w - when I try to clean it up eraser it stills looks messy - Is there a better way to do this?

Thank YOU All!

Here an image we can use as an example. If you look closely at the Santa Hat you will see some areas (small) that look orange - How can I clean it up ? or Am I just beeing too picky or perfectionist?

Thank You

"some areas (small) that look orange - How can I clean it up ?"

Those orange areas is where you were not precise enough in applying the history brush. Either you used a feathered brush, or you simply touched areas with the history brush that you shouldn't have.

Clean it up by
1) zooming in, selecting the orange areas, and desaturating them (see attachment), or by
2) doing the whole thing again from scratch. But obviously zoomed in more, and applying the history brush – sans feathering! – PRECISELY.

BTW: that part of the image is woefully underexposed... As is the whole cat, actually!
