I work with JPEG imiage, don't shoot RAW.
Duo Tone:- CS3, top menu -
1. Image>Mode>Gray Scale. Choose Discard Colors. Photo will change to BnW/Gray Scale.
2. Image>Mode?DuoTone. Window opens, choose the type of duo tone you want. I use the default of black/pantone. You can click on the colors for variations. I choose this for the sepia like effect.
3. Image>Mode>RGB. Change image back to RGB.
You should see the duotone effect in your photo.
Gaussian Blur:-
1. Filters>Blur>Gausian Blur.
I use 30% blur.
Adjust the Radius for the amount of blur you want.
That it.
Of course you can use layering for non destructive PP. But I'm too lazy so do direct PP.
Need more info let me know.
Thanks, Teerex, for such detail steps for me. I will try out this method on my PP.
