I am trying to create an overview image with gdaladdo and tried out 
different resampling parameter. My results looks fine on large scale, 
but zooming out (small scale) the image looks really poor. What I want 
to to achieve or reproduce is an effect like in ArcMap. Here embedding 
an black and white image and enabling the 'create Pyramids' option, it 
generates a really smooth image on small scale. Any idea or suggestion 
how to achieve this effect? Or is this an special ArcMap effect?

Thanks for any suggestions and best regards,
Toni Pignataro
