well its hard to describe. its a certain feature on my camera, that you can select a highlight color for a BW picture and that is the only color that will be shown. i have a Canon A430, its not an expensive or extravagant camera, but it sure does take good pictures!
Fantastic :)
The yellow daffodils looks wonderful against the B&W.
Personally I'd prefer only the yellow and not the little patches of green dotted about too but really well done.
What software do you use?
I actually don't use a software program, all of my pictures are taken by my camera and put directly on here so none of them have been modified. I captured this picture using a special feature on my camera where I can accented a certain color on a black and white. But the green grass must have had bits of yellow in it so that is why it picked up the green shot. I don't really care though...I love this shot!
