1. This is the original picture
I used the spot healing brush
to smooth over any blemishes
on my model

2. Then I auto toned the image
to balance the picture and
make all the tones and
contrasting even. Then I
made another layer so I am
not working on the original
image.
Then I clicked on
adjustments and chose black
and white where I was able
to fiddle and play around
with the colours to make the
desired black ad white effect
which I wanted

3. Then I got the lasso
tool
And lassoed all around
the mouth

4. Then deleted the lassoed
bit of the layer which
reveals the red underneath
from the original image
