Under the premise of complying with anti-discrimination laws, you can reasonably explain the model selection criteria from the following angles. These recommendations need to be combined with specific project needs, and it is recommended to consult legal counsel in advance to ensure compliance： 1. Brand positioning and target market 1. Target audience matching - "Our core customer base is consumers aged 18-30, and we need to choose models that can visually resonate with them." - "Product characteristics (such as e-sports equipment/campus clothing) need to present the authenticity of specific life scenes" 2. Visual communication requirements -Emphasize that advertising creativity requires specific image symbols: "This series focuses on a sense of future technology and needs to show breakthrough modeling expressiveness." - "Flat shooting requires strong facial contour expressiveness, and a three-dimensional facial scanning test is required" 2. Professional and technical dimensions 1. Special skill requirements - "The project includes high-altitude Weiya shooting, and a physical fitness test report for the past three months is required" - "Digital human modeling projects need to be combined with 10 hours of motion capture and need to be tested for endurance" 2. Industry experience accumulation - "Need to have virtual live broadcast experience or CG synthetic shooting resume" - "Requires familiarity with the fast-paced TVC shooting process (15 sets of styling changes in a single day)" 3. Business value considerations 1. Market data support - "According to the test report of a third-party eye tracker, the target population's facial recognition of a specific style is 37% higher." - "Social media portraits show that in the content of user preferences, the dynamic expression index accounts for 62%" 2. Production cost optimization -"Cross-border shooting requires continuous work for 18 hours and a recent health certificate is required" - "Professional free diving certification is required for underwater shooting" 4. Key points of legal risk aversion 1. Recruitment copywriting specifications -Avoid using age descriptions and replace them with: "Seek candidates who can show a sense of youth and vitality (sports brand cooperation cases need to be provided)" -Use neutral standards: "Facial features must meet the aesthetic parameters of the golden ratio" 2. Design of assessment mechanism -Establish a multi-dimensional evaluation system (expressiveness test, lens adaptability score, modeling conversion speed, etc.) -Retain decision-making basis such as audition videos and scoring tables It is recommended to establish a talent pool simultaneously and establish a digital archive according to style and type, which not only ensures the flexibility of casting, but also forms an objective selection basis through data accumulation. For special projects, CGI technology can be considered to assist in achieving specific visual effects to reduce the sensitivity of real people's choices.
