Smartphone camera quality has been progressing alongside the advancement of the smartphone market. Consequently, there has sparked interest in macro photography of insects using smartphones either through using built-in "macro mode" or accessories like macro lenses, mounts, and auxiliary lighting. However, some limitations have become apparent, including challenges in capturing small insects, a short focal distance of no more than 10 cm, a narrow focus range, and lower image quality compared to dedicated cameras. We introduce an effective knowhow to these problems when taking pictures of insects in the field using a smartphone. And it provides a manual for tele-macro photography in the field, and suggestions for the future direction of smartphone and accessory development.
