Using reflector, it turns out Image.Save() boils down to the GDI+ function GdipSaveImageToFile with the encoderParams NULL. So I think the question is what the JPEG encoder does when it gets a null encoderParams . 75% has been suggested here, but I can't find any solid reference.
IIRC, it is 75%, but I don't recall where I read this.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
