<a href="https://en.wikipedia.org/wiki/Northern_Lights" class="extiw" title="w:Northern Lights">Northern Lights</a> photography course in <a href="https://en.wikipedia.org/wiki/Mosfellsb%C3%A6r" class="extiw" title="w:Mosfellsbær">Mosfellsbær</a>, <a href="https://en.wikipedia.org/wiki/Iceland" class="extiw" title="w:Iceland">Iceland</a>, which Gunnlaugur B. Ólafsson did organize and Anne-Claire Lefèvre from France did teach.  We started in Mosfellsbær and hiked up at <a href="https://is.wikipedia.org/wiki/%C3%9Alfarsfell_(fjall)" class="extiw" title="is:Úlfarsfell (fjall)">Úlfarsfell</a> (small mountain in the capital area in Iceland) where we did take photos of the lights in <a href="https://en.wikipedia.org/wiki/Reykjav%C3%ADk" class="extiw" title="w:Reykjavík">Reykjavík</a> and some northern lights photos... which was hard because the eye did hardly notice they were there even thought the <a href="https://en.wikipedia.org/wiki/Lens_(optics)" class="extiw" title="w:Lens (optics)">lens</a> did notice when kept long enough open.
