6. 個人經驗與觀點
「自拍嘅時候，你以為自己見到嘅就係真實？前置鏡頭影出嚟嘅你，同你照鏡見到嘅自己，其實係左右調轉嘅。我第一次發現呢個事實嘅時候，真係呆咗——原來我一直以為嘅『自己』，只係一個鏡像。鏡像翻轉唔單止係一個編輯功能，佢係一個 改變觀看方式 嘅工具。你將一張相水平翻轉，你睇到嘅嘢完全一樣，但感覺完全唔同——因為你嘅大腦對左右嘅敏感度遠超你嘅想像。呢個工具俾你嘅，就係 控制點樣被人睇到 嘅能力。」

6. Personal Insights & Expert Advice
"When you take a selfie, do you think what you see is reality? The you from the front camera and the you in the mirror are actually left-right reversed. The first time I realized this, I was stunned—what I always thought was 'me' was just a mirror image. Flipping isn't just an editing function—it's a tool that changes how you're seen. Flip a photo horizontally, and everything looks the same but feels completely different—because your brain's sensitivity to left-right orientation is far greater than you imagine. This tool gives you exactly that power to control how others see you."
