I recently have looked at quite a few B/W images in the forum and on the Internet. I have notice some have some color highlighted in them. My question is how is this done. Can someone explain. In as simple terms as possible please. Would Like to have a go at this as it looks interesting technique.

In simple terms, you use 2 copies of the same image on different layers. You make the top copy B&W, then you use whatever the tool is called in your favourite editing software to gradually make more parts of the top image transparent, revealing the coloured part from the image below.

another way to skin that cat is to convert your image to b&w in PS and then use the history brush to bring back the color to specific areas
Fired many shots. Didn't kill anything.

Hi,

I've only really had one serious attempt at this...




I used GIMP, and desaturated all colours except red. (GIMP's satuation tool gives you red, magenta, blue, cyan, green and yellow, of which you can change all hues accordingly.. I don't know how PS does this) I then checked for any stray red that I didn't want.. there were a few leaves on the ground for instance.. then selected the areas seperately and desaturated where needed.

Once I'd figured out what I wanted from the image it took only a few minutes.

Cheers

Liam what a fantastic image very sharp and clear

Dare I ask what camera/lens was used and if any post editing re: sharpness was applied

I tried this some time ago, I used the method suggested by Mannesty, I created a second layer, desaturated the first layer then erased all but the poppy on the second layer.

And before you all applaud the image....the composition was a fluke, we were visiting the allied war cemetary on Crete, and I noticed the cross on a memorial, I was about to press the shutter when my wife intervened, she had found another cross and was about to suggest I take them together, she was in the process of placing it as I was composing the first shot, introducing the shadow just as I pressed the shutter.

Hi Pete,

ist DL, with 18-55 kit lens. I took it almost a year ago now, so I can't remember what I did to it exactly, but almost certainly no more than my usual sharpening..

Unsharp Mask

Radius 5.0
Amount 0.4
Threshold 0

There is a term for this type of sharpening, something to do with contrast?? Matt did tell me exactly what it was, but I can't remember the ins and outs precisely.. it just works for me.

Off out for a beer..

Cheers

I Know, but I also have to confess that I initially had a go at the wife for ruining my shot even more embarrasing because it turned out to be the best of the bunch and the only one I kept

I did make it up to her by buying her a nice lunch (with her money )

Now totally of topic;
the allied cemetary on Crete is a beautiful place, extremely well tended, well worth a visit.
Be prepared to leave there with a heavy heart though.

What you show there Liam is a straight USM.

If you use a large radius - that's called LCE - Local Contrast Enhancement. Perhaps that's what you were thinking of.
(e.g. try: Amount 50%, Radius 50, Threshold 10)

Hi Matt,

yep, that's what I was thinking of..

The above settings are almost the defaults for USM.. in GIMP at any rate, I just take the Amount down from 0.5 to 0.4 when used..

Being a mono fan and wanting to try different methods I was fascinated with Liams images, so used Don's instructions as I use PS and created this




for those you need a few more pointers this is what I did:

convert image to mono whatever way you normally do
adjust levels etc
switch back Image Mode to RGB
select History Brush Tool and rub over the area carefully you wish original color to be revealed


if I need to be corrected on this feel free to say so, just how I worked it out meself
It rather a thing to do...as long as its not over done

Can you do this type of thing on Photoshop Element 5 as I would like to have a go. I am using a trial version at the moment. If so can someone tell me how. I have tried several times but cannot seem to get any results. What am I doing wrong???

You can do this even on older Elements versions, not sure where the controls would be though...

My suggestion would be to select using the magic wand and then desaturate all the colours in enhance>adjust colour>hue/saturation

EDIT:
The dodge tool can be used to manually desaturate areas.
