Oh ok...
I just saw the country specific guide for INDIA and i found out this.
8. PHOTOS
Supply six (6) recent photos for each member of your family and yourself. Read the instructions in your guide in the following sections:
•“Completing the Immigration Forms” and,
•Appendix B: Photograph Specifications.
Appendix: B reads like this
Notes to the applicantTAKE THIS WITH YOU TO THE PHOTOGRAPHER
•Immigration photos are not the same as passport photos.
•Make sure that you provide the correct number of photos specified in this guide.
Notes to the photographer
The photos must:
•show a full front view of the person's head and shoulders showing full face centered in the middle of the photograph;
•have a plain white background;
•be identical (black and white or colour) produced from the same untouched negative, or exposed simultaneously by a split-image or multi-lens camera.
The photos must:
•measure between 25 mm and 30 mm (1” and 1 1/5”) from chin to crown;
•have a 35 mm x 45 mm (1 3/8” x 1 3/4”) finished size.
So thankfully, the above rule doesn't apply to INDIA.
But I must thank you dadaem for letting me know about this...Else i would have cursed myself for not having done this correctly.
