Art student in need of source material. How weird would it be to ask strangers if I can photograph them to paint? Where is the best place to ask?

I’ve been recommended by multiple people in the art department to diversify the painting portraits I make. I paint myself a lot because of convenience and I paint my roommates and family members when I see them.

I’ve been suggested to paint more people of a variety of different races and ages.

I have to photograph the people myself however or I’d ask people on the internet for photos. What advice would you have?

Should I ask an old folks home for permission to come and photograph and paint people who consent? Approach people in public? Not sure what is the most effective and least invasive way to get more source material.
