Who is not familiar with photos like these :-) ?  A great subject, but underexposed. This example shows that, with appropriate image processing software - for example, Photoshop - together with B+W software filters, nothing has been lost.

In order to bring out the face better in this portrait, it was first masked with the appropriate image processing tool and then made more luminous with the Brighten Filter. After that, the entire picture was also given a little brightening because of the many shadow areas which it contained. By using the Soft Focus and Warming Filters, what emerged was an ethereal, summertime portrait. By using the Enhance Color Filter, the blue color of the T-shirt could be restored.
