When the portrait becomes a compliance question

Most headshot decisions are matters of taste. Some come with published specifications, and those change the process entirely.

Where this happens

Medical residency applications, professional registrations, competition entries, some institutional directories. They state dimensions, sometimes a background colour, sometimes a submission deadline.

Why it matters more than it sounds

A rejected photograph does not cost a retake. It costs an application cycle, and the requirements are usually published somewhere unhelpful — a PDF appendix rather than the page you were reading.

The order that avoids it

Find the specification first. Produce the portrait second. The reverse order is how people end up with a beautiful headshot in the wrong aspect ratio a week before a deadline.

The part that is still a judgement call

Within the specification, the same three variables decide legibility: contrast between hair and background, crop, light direction. A compliant photograph can still be a bad one, and nobody checks that for you.
