Keep messages minimal

Do not send passwords, payment details, private photos or camera-account access. A few entered numbers and steps normally suffice. There is no on-site contact form and no upload facility. Choosing the email link opens your email application; using the calculator does not send a message.

We welcome reports of incorrect arithmetic or unclear model assumptions. The site does not offer personal lens recommendations, physical setup certification or a guarantee that the ideal rectangle matches a real camera. See the model limits and privacy information before sending details.
