What legal precaution should be taken when photographing others with a camera phone?

When photographing others with a camera phone, it's essential to obtain written permission rather than verbal consent. As Ed Helms discovered in the case of Helms v. Wong, verbal permission will not hold up in court, potentially leading to legal complications. Camera phones represent a technological advancement that improves users' quality of life while simultaneously creating privacy concerns for others. While these devices offer convenience and functionality, users must balance their technological benefits against the potential invasion of others' privacy rights.
