Tips on taking high quality pics for rhinoplasty morphing?

Hi there! Rhinoplasty morphing is most effectively done in a clinic with proper software such as Mirror or Uniplast. Most rhinoplasty surgeons have a studio with proper lighting and positioning to achieve excellent photos. There are certain angles and dimensions which need to be followed to ensure standardization. There are apps on the iPhone to perform your own morphing, though I wouldn't place much weight in them given the limitations. If you're serious about accurate morphing, seek consultation with a facial plastic surgeon who routinely morphs photos taken in clinic. Hope this helps.

There are standards for cosmetic surgery photography. The The American Society of Plastic Surgeons have a booklet for sale on these standards. I wish Realself can post these standards.
No blacking out of any part of the face or any part of the picture. Blacking out the eyes and half of the nose is not acceptable and usually I do not look at it to answer.
Best to have another person take the phograph. Selfies tend to be tilted and not straight and symmetrical
Face and nose pictures should be from the top of the head to the mid neck. Straight frontal view, lateral profile and 3/4 view and with head tilted back to show the nostrils. Closeup views only to evaluate a specific lesion, or detail of a specific problem along with the above photographs.
