What is a custom domain for a photography portfolio?
Short answer
Pointing your own domain (yourstudio.com) at your platform account so clients see your URL, not the platform.
Full definition
A custom domain is your own purchased domain (e.g., gallery.yourstudio.com) configured to point at your platform account via DNS. Clients receiving a gallery see yourstudio.com in the URL bar, not 12img.com. 12img Starter and Pro include custom domain support with automatic SSL provisioning via Vercel and Let's Encrypt — no manual cert management required.
