NTA has different guidelines and checking personnel will have different guidelines. The photograph that you upload has to meet NTA's guidelines regarding clarity of the face and ears. But in your case, the photo wasn't clear was your concern. And if NTA approves of the photograph, you can take the same photograph to the examination hall as well. NTA suggests that each Candidate take 6-8 Passport size and 4-6 Post Card size (4”X6”) colored photographs with white background. The photographs are to be used for uploading on Online Application Form, for examination and also for Counselling and Admission. So if NTA doesn't notify you asking you to change your daughter's photograph, you can let her take the same photographs for examination as well.
