6. 個人經驗與觀點
「N年前做設計嗰陣，客要求將佢張相變成卡通頭像。當時我開住 Photoshop 搞咗成兩個鐘，仲要逐條線描、逐個色塊填。而家一個掣就搞掂，仲有 5 種風格揀。風格化唔只係『玩吓』，佢係一個 重新定義你點樣被睇到 嘅工具。一張普通相，可能一秒就被掃過；但變成卡通或素描之後，人哋會停留多兩秒——因為佢 唔係一張相，而係一件『作品』。呢個轉變改變咗觀眾對你嘅 感知。一個掣，改變你嘅形象。」

6. Personal Insights & Expert Advice
"Years ago, a client wanted me to turn their photo into a cartoon avatar for their brand. I spent two hours in Photoshop, tracing every line and filling every color block by hand. Now it's one click—with 5 styles to choose from. Style transfer isn't just 'playing around'—it's a tool that redefines how you're perceived. An ordinary photo gets scrolled past in one second. But a cartoon or sketch version? People pause for two extra seconds—because it's not just a photo, it's a 'piece of art'. This transformation changes how your audience perceives you. One click, image changed."
