Whether it be text or another element, I
love playing with this negative / positive effect in an image.
I think it works best with a clean looking
image but it is worth trying even with a black and white photograph.
Here is an ultra easy method.
Demonstrated in PSP 9.
Select
your image and size as you wish ..whether black on white or white on black.
Select the area which you wish to colour
invert...here I used the circular selection tool.
Make sure you have NO feather and anti alias
is checked.
Promote selection to layer [not absolutely
necessary but I like having it on a separate layer.]
Now go to Adjust>Colour Balance>
negative image.
[In later versions of PSP you will find it
under Image>negative image]
Select none and save your image. :)
If you don't like the effect on the area that
you have selected it is a simple matter of deleting that top layer and starting
again.
Frame it if you wish and stand back and
admire your handiwork!
