The safest starting point is the application itself: identify the document, the country, and whether the photo is being uploaded, printed or both.
Design the output around the paper
For physical photos, the paper is the canvas. Decide the finished photo dimensions, number of copies, spacing and safe margins before exporting the sheet. Then make sure the print dialogue does not rescale the page.
A small test prevents a large reprint
Measure one printed copy after the first run. If it is larger or smaller than intended, stop and correct the scale setting before printing the entire sheet. “Fit to page” is convenient for ordinary documents but can change the physical size of an ID photograph.
What to set up in the room
Use a room where the light is broad and even rather than a single harsh lamp directly above the head. Put the subject far enough from the background that a strong shadow does not become part of the photograph. Keep the camera roughly level with the face and avoid dramatic wide-angle distortion from an extremely close phone position.
A useful home test
Take one frame, stop, and inspect the eyes and background before taking the rest. If the eyes have a catchlight but no hard glare, the face is evenly lit and the background has no distracting edge, you are starting from a much better source file.
Do not let the editor hide the problem
Zoom in and inspect the exported image itself. A crop boundary, background halo or compression artefact can disappear in a small preview and become obvious after upload or print.
The physical result deserves its own quality check
When the final output is a print sheet, check one physical copy rather than trusting the preview alone. A printer can introduce scaling, border expansion or colour shifts that are invisible in the exported PDF or JPEG. A small ruler or a known reference measurement can confirm the actual dimensions before you produce the full batch.
Practical detail to carry forward
When you are done, open the final file once more from disk rather than from the editor. That confirms the exported file—not just the preview—contains the intended crop and dimensions.
