[Insight-users] 3D image iterator problem

[Cagatay Bilgin]

This is the only part of your code
that will make the image brighter
than it is.

 else if (in.Get()<50)
               {
                       out.Set(50);
               }

I am assuming that you are expecting
to see an increase here. This is not
unexpected increase in brightness :)

Let us know,
Cagatay
