I suggest you tell her that she
looks beautiful as she is but if she wants to change her hair colour (that
shall include her eyebrows) to black she should go to a hair dresser and
as for it to be dyed and then re-take the photograph.
I believe that you can change her
hair colour, including her eyebrows, in Photoshop by selecting the hair
using the magic selector then use the colour control but you would have to
do it in stages as the highlights need different treatment to the shadows.
I also think it is too difficult for me.
Changing her hair colour would mean
that her complexion would not match her hair and so she would not look
“right”.
My
girlfriend, otherwise known as She Who Must Be Obeyed, said she liked this
portrait I did of her. But she wants me to change the color of her
hair to black. I said that would be very difficult,
considering my limited skill with Photoshop. She said,
"Try."
Any
suggestions will be deeply appreciated.
