Question:
Should one recite the blessing over seeing a picture of a very unusual looking person?
KS"A 60"13
Answer:
As a general rule for all Birkas Hariyah, we don’t say the bracha when seeing the item in a picture. This is because we haven’t actually seen the item, and because we are not as impressed when we see the item merely through a picture.
