Graphicconverter for OSX didn't add Dodge/Burn capabilities until version 9.2 this month. This is quite amazing that it was missing until now considering they are trying to compare to Adobe Photo shop. Using this  functionality will likely achieve what you are describing, although you could also do it with layers and fine selection of the hair depending on the image.

Darken gray hair in GraphicConverter?
I am creating a website using asp.net and c#
I need to access all files one by one in a directory. So I wrote the following code.

    string[] ssImgs = Directory.GetFiles("images/movies");
    Label1.Text = ssImgs[0];
    Label2.Text = ssImgs[1];


But it gives an error. What is the correct way to do this? Thanks in advance.
