For almost all photos and videos on my website a license can be purchased to download and use the file. The price depends on the print run size, image format or video length and online reach.
Here you can request a license.
My picture and video material can be used with indication of the source, provided that no commercial purpose is connected with it.
To show pictures or videos on a private page, for example, or on social media with a private profile, a request is desired but not required.
I expect a reference to the source with the following credits: Edgar Müller – metanamorph.com
