用戶真實評價
來自創作者、店主和設計師對該工具的真實使用體驗
“以前我用手機拍的商品圖，放大後總有點偏灰、偏模糊，放上商店顯得很廉價。用這個增強工具處理一遍，銳利度和色彩馬上回來，商品看起來終於像專業拍攝的了。”
“我會把手機拍的影片截圖和很小的封面縮圖先處理一遍增強。雜訊沒了、邊緣變清晰，以前弱光下拍的舊素材也能修到可以直接發布的乾淨效果。”
“我常在戶外拍攝，有些照片因為手震或高 ISO 而有雜訊、模糊。它能保留自然質感又把這些瑕疵修乾淨，每次拍攝能交付的可用成品明顯變多。”
“投放付費廣告前，我們會把低解析度的包裝圖和舊素材重新增強一遍。整批圖片明顯更銳更亮，最後上線的廣告在各種版位上都清楚很多。”
“做課堂簡報時它把模糊的手機照片修得很清晰。少數紋理非常複雜的圖偶爾會顯得太過處理，但作為免費且免註冊的工具，它很輕鬆就完成了我的整個專案。”
“客戶常發來多年前拍的、或從舊貼文截下來的圖片。我統一增強成一種清晰風格後，內容排程終於看起來很精緻，也不用花錢請修圖師。”
“日常照片的提亮增銳效果確實不錯，多數貼文的成果我都很滿意。但拍近距離自拍時磨皮偶爾會過頭，有幾張我在發布前又處理了一遍。”
“把渲染圖和粗略的草稿效果圖寄給客戶前，我會先提高銳度。線條和小細節都能保留，早期概念圖在螢幕上的觀感一下子好很多。”
