My son in front of the Sk?gafoss waterfall in Iceland. Iceland has numerous waterfalls, some of them ever bigger than this on. But Sk?gafoss provides the opportunity to walk right "into" the waterfall, so you can place people right in front of the base in order to have a size comparison to these masses of water, coming down like dust. So I asked my son to walk as close as possible to the base, which was a rather wet experience for him. I hope he still finds worth it.
I got exactly the picture, which I had in my head.
