Start with the moment of submission. What will the form ask you to upload or hand over, and what exact checks can fail? Work backwards from those answers.
Make the session easier before touching the editor
Prepare the room, background and camera before bringing the applicant into position. For a baby or an applicant who needs physical support, take several originals and choose later. For an accessibility situation, follow any authority-specific accommodation instructions rather than forcing an adult “standard pose.”
What to keep from the session
Save the original frames and note which image was used. That makes it possible to produce another required output later without reshooting the applicant under time pressure.
One final question
Does this exact file match the exact application? If the answer is yes, save it and move on. If the answer is “probably,” go back to the authority page before submitting.
Small subjects change the photography problem
With babies and young children, the challenge is timing rather than software. Set the scene first, take multiple originals and choose the best one after the child has settled. Official authorities may also have age-specific exceptions—for example, some allow younger children more flexibility about eye position or expression. Never generalise an adult passport rule to a baby without checking the specific authority.
A note for this exact search
For this particular topic, save the final version with the destination and date in the filename. That makes a second application easier to prepare without guessing which export you used first.

For online workflows, verify the final dimensions and file size on disk before uploading.
