Here's a sample of a perfect photo to cut your silhouette portrait by... and examples of photos that will not work!
3/4 Photos won't do at all! Sorry!
Trying to cut left profiles is a pain! The blades from the scissors get in the way!
See what I mean? Can't see what I'm doing...
Don't cut off your subjects' head and hair! That leaves too much guess work!
See how a smile actually distorts the mouth and cheek area? No smiles please!
Don't tilt your head! A plain background is good, though.
Goodness she's lovely... but please, no front-facing photos!
This is the perfect RIGHT profile. Stand about 4 feet away from your subject, show all the head, all the hair, and NO smiles! Please take individual photos of each person, no matter what!
