The post explains that recognizing faces in real life relies on many angles, whereas a single photo gives only one view that can be further distorted by lenses, software, lighting, focus, color, and expression; to overcome this, the author suggests using photogrammetry with neutral lighting and free tools such as Meshroom, Blender, and PrusaâŻSlicer to build a 3âD model of a portrait, which then allows you to see the subject in three dimensions and understand its main angleâso even if your painting starts from one photo, you should gather several minutes of video and dozens of photos taken at slightly different angles and lighting. The author notes that seeing multiple shots can sometimes make people look like twins, a common problem in art when reproducing the wrong âtwin.â Finally, he argues that stylised paintings are as valuable as hyperârealistic ones; capturing a stylised eye while keeping the subjectâs appearance takes time but is part of learning and bridges the journey from hyperârealism to beautiful stylisation.
