Black and White conversion w/ some color

[cmulcahy]

I'm using a D300 and captureNX for my post processing. Is there a way to

convert to black and white but have one object remain in color? For example A

black and white picture with a red apple and the apple is red - everything else

is in black and white.

 

If captureNX cannot achieve this effect what would you recommend? Are there

add ons available for captureNX?

 

thanks

photoshop, do a B&W adjustment layer, then make it a layer mask, paint out the areas you wish to restore color to, adjust the pressue of your brush, or teh opacity of the layer. J

Much easier to do in NX if you have it...

 

Do a black and white conversion, then use the minus brush to brush off the apple.

 

Works great!

This is easy in Photoshop. Go Image>Adjustments>Hue/Saturation. Then simnply desaturate each colour in turn except red. Much easier than having to paint a mask. And you can always give the 'red' a tweak while you are in there. Here is an example. Not an award-winner but done in minutes just for this post.

The other way would be to 'Select' the apple by whatever tool you use for selections, then go 'select'> 'inverse' and turn the rest of the picture into monochrome

Since no one else has said it, I feel compelled to add: This effect is tacky and overused. Use sparingly.

Couldn't agree more Kevin. The effect looks very dated nowadays.

 

It was just that Chad wanted to know how to do it.......... <IMG SRC="http://mars.walagata.com/w/radiogandy/Icons/photo.gif">

I don't agree with a few things that have been said here.

 

Photoshop is the best tool for this in my opinion. Just to desaturate is not a very good way to get b&w. PSCS3 has a nice b&w tool under image>adjustments with some presets that work well under many situations. And I think you have to mask to get an accurate result.

 

Also I don't think it is tacky when used right. You can decide for yourself if my example is "used right" or not. This is my wife, and it is amazing how often I have shown someone this photo and they have said something like "I didn't know her eyes were this color", so in my opinion at least it can concentrate your viewer's attention on a specific item. I think it is a useful tool.<div></div>

It's simple to do with Photoshop, and the technique is described in details on many <a href="http://www.pdn-pix.com/pdn/cp/olympus/technology/article_display.jsp?vnu_content_id=1001700324">pages like this one</a>.<br>

It helps highlight an object or an area of the photo.<br><img src="http://img72.imageshack.us/img72/3596/daffodilspx1.jpg">
