照片跟實景物顏色不對,有救嗎?

如果你曾在昏暗天色下拍攝雪景,不難遭遇照片偏藍,有時就算在燈火通明的室內拍拍人像,照片放大時也會發現人像與背景間出現怪異的藍邊,有這類色差不代表你的相機有問題或者是時候買新的,而是一種常見的光學失真。你若要求不高,大可說色差很moody,不了了之立即貼上Facebook。

但如果你的照片是用來謀生的話,例如是網上商店的產品照,你就必須認真解決它。

當然有專業的器材及攝影棚是很理想,否則你可使用Photoshop調整色調和飽和度,就算是傻瓜機照或手機照也好,你均能輕鬆將色彩還原真實,甚至令照片感覺更專業。

If you ever shoot snow scene in the darkness, you may get bluish photographs pretty easily, sometimes even you shoot portraits in brightly lit indoor, strange blue fringings may be found when you enlarge the photographs.   The occurrence of Chromatic Aberration does not mean that your camera is problematic, nor it is a excuse for you to buy a new camera, it is a common optical distortion.  Of course, if you aren’t demanding on your photographs, you may find the distorted photographs “moody” and upload them on your Facebook without any consideration.

However, if the photographs are important to your business, e.g. photos on your online store, you will have to fix them seriously.

Indeed, professional equipment and studio are ideal, otherwise you can use Photoshop to adjust the photo hue and saturation.  You can easily restore into realistic colors even on photographs taken by cheap digital cameras or cell phone.  Furthermore, you can retouch them into a professional level.
