Occasional. By email.
A few times the year, when there is something ready to be shared.
When I finish a series or have a message, I write to a small list of people. It is not a newsletter about the practice of photography and it is not on a schedule. It goes out when there is something worth saying.
There is no form on this page and no service behind it. Clicking below opens an email to me. I personally add you, and the list lives in my own mail — it is never used for anything but this.
Or write to [email protected] directly. To come off the letter, "stop" in the subject is enough.
