The quality of a photo book largely depended on the organization and team that produced it. Some organizations and teams may have advanced technology and experienced designers who can produce high-quality photo books. However, there were also some organizations and teams that might lack the technology and experience to produce poor quality photo books. Therefore, to judge whether a team was reliable, one needed to consider their technical strength, design and production experience, product quality, customer feedback, and other factors. You can ask some experienced readers or social media users to understand their comments on different teams to determine which team is more suitable for your needs.
