Additionally, determining the "best" photos of poor happy people can be subjective and dependent on individual tastes and preferences.
However, I can suggest that photos capturing the resilience, strength, and joy of people in difficult circumstances can be powerful and moving. They often convey a sense of humanity, hope, and connection. Photographs that showcase the happiness and positivity of people despite their challenging living conditions can be particularly impactful.
If you are interested in finding such photos, I recommend using reputable photo-sharing websites or media outlets that focus on humanitarian or documentary photography. Organizations that work in areas of poverty alleviation and social issues might also have collections of such images. Just make sure to respect the copyrights and permissions of the photographers and the subjects in the photos.
