Hello Aspirant,

See it is recommended that you should upload clear photo which is 100% visible but if there is slight variation or little blur which can be neglected then you won't receive a mail regarding image discrepancy but you should re-upload it in very clear manner so that the photograph should be 100% visible and even if you don't upload it again and also do not receive the mail then also there would not be any problem because if there would be any serious issue regarding your image then NTA will inform your for sure before rejecting your form.

NEET 2021 Correction window will open August 8th 2021 and will remain active till August 12th 2021 so make sure to modify all the details whichever required.

I hope this information helps you.

Good Luck!!
