Photo usage

Every photograph on this site was taken by me, with one exception: the portrait of me on the About page, which someone else took and which is credited there. Mine are not stock, they are not free to use, and they are not in the public domain. All rights reserved.

What you may do

What you may not do without asking

Every file says who took it

Each photo here carries my name, the copyright notice and a link to this page inside the file itself — in EXIF and in the IPTC metadata that editing software and search engines read. That holds for the versions this site serves, not just for the originals in my archive: a copy saved from this page still knows whose it is. The same information is repeated on the page in a form search engines parse, so a photo found through image search comes with a credit and a route back here.

Machine learning

I do not permit these photographs to be used as training data for generative models, or scraped into any dataset assembled for that purpose. This applies whether the scraping is done by a person, a crawler or an agent, and it is not waived by the site being publicly reachable.

That is not only a sentence on a page. It is declared in a form machines read: the crawlers that gather training data are turned away from the image directory in robots.txt, a reservation of rights under the TDM Reservation Protocol sits at /.well-known/tdmrep.json, and every response this site sends carries tdm-reservation headers pointing back here. Text on the site stays open to crawlers — this is about the photographs.

Just ask

The answer is usually yes, and it is usually free — I mostly want to know where a photo ends up and to be credited. Write to hi@matejsamec.cz, tell me which photo and what for, and you will hear back.

If you have already used one

Email me. Taking it down, or adding a credit and a link, settles it in almost every case.

These terms are not legal advice and carry no contract of their own — they describe how I license my own work. Last updated 15 September 2026.
