Hi Gisela - 2 images as suggested - hope this is what you mean

Yep! Please see example I've put one layer on top of the other using Photoshop and move them in certain positioning to eliminate the grains and brought them into one single photo. I've barely cleaned the photo just got rid of couple big circle spots. The photos are smaller size to your original I've noticed but anyway just giving you an idea.

Wow! what a difference - very clever
