I had my daughters pictures done by a professional that LOVES to airbrush EVERY imporfestion. My daughter has birthmarks on her forehead and its something that I've always loved(they are faded now) but she photoshopped them out. Something like that I would leave BUT something like cradle cap(IF you can take that out) I would. That isnt pretty when trying to sell a product.
In the second picture you can see her birthmark in the center of her forhead and her eye lids. I wish they were left out in the previous picture BUT, I'm NOT disappointed with the pictures. They are fantastic!
