My girlfriend Jenna volunteered ...(volentold) to be my test subject for this attempt.

I took 4 sets of photos for this try

1 under her chin

1 angled upward from her chin 

1 directly at her face

1 above looking down

In photo-scan these were the settings I used

I am in no means an expert but these setting seems to work fine for me and did not take days to compute
