I like the look of photos that have been changed to grayscale/desaturated, EXCEPT for one color. Can this be done with a photo that has been changed to grayscale, then duotoned to a sepia tone - (all sepia toned except for one other color)?? I have tried several different things in Photoshop, but have been unable to achieve this. Anyone know if this is possible?

Thanks,
Linda

I'm not even sure how it is done with all grayscale but one color (legally for DPC, of course). I would love to know that, as well as for sepia.

In Photoshop's duotone mode you are mapping gray values to one or more color inks. you can do what you want if the area you want colored consists of a shade of gray which doesn't appear in the rest of the picture. Then assign zero values to the color's tone curve except for the gray value(s) of the specified area.

If you want, email me a small file of the type you're working with and describe what you want, and I'll try to make a rough example you can experiment from.

What you wanna do is start with a colour image and then select the hue/saturation/lightness editor. There, you can select various colour channels and desaturate all the ones except the colour/colours that you want.

Firstly, are you wanting to do this, just in general, or legally for dpc ?

Non dpc legal, I've done it this way:

First make a duplicate version of the image.

In the duplicate make a selection of the area/colour that you wish to preserve (this tends to work out better in the end if you can feather the edges) then copy that region into a new layer, so that you have a new layer with just the area/colour that you want to have in your final image.

Now, on the original version, remove the colour(I use the channel mixer to do this) convert to greyscale, convert to duotone and tone it however you want, then convert the duotoned result back to RGB. (this last step is important!)

Then, with both images on the screen and the one with the colour layer active, drag the colour layer with the shift key pressed to the duotoned image, and drop it. (the shift key aligns the layers)

You should now have your duotoned file with the original coloured area.

Thanks for all the replies. I want to do this as part of my photography class assignment. I'm going to try a couple of the suggestions, then if it doesn't work, I'll be PM'ing somebody!!

Gordon, I kept trying to drag my saved selection into the sepia image, and it became sepia as well. I think the part that I missed is the (important) changing back to RGB thing. Gonna try it....

Yup - when you drag it in, it'll get autoconverted to the colour space the destination image is in (duotoned in this case) in which case it'll get converted to a new colour which you probably don't want.

If you change the duotoned version to RGB it will look the same - as it gets mapped back to a much larger set of colours, and when you drag the layer it will stay the same. the 'shift' drag, just helps line things up automatically.

Gordon, you're a genius!! It worked beautifully! This was the last shot for my final portfolio, and I was having a terrible time with it. You saved me, and the photo.

My problem with desaturating the photo was that there were TWO areas of the color that I wanted, but I only wanted ONE of the areas to remain that color. Doing it this way solved everything.

Thanks again for the replies !

Gordon beat me to it. I use that way alot, and works great. I have also (with a small area-like in this one //www.dpchallenge.com/image.php/i/14093)
made a copy, erased the area, magnifying it to touch up the areas (or you can magic wand/erase), and then place the color version under the sepia toned.
