Anyone heard or tried this technology?

magic lantern 真係搞野，唔知會唔會提供咗相機發展新方向？

其實以前Fujifilm都好似有 sensor 分高低感光以拍出更大 Dynamic Range, 但今次 magic lantern 就sensor本身設計缺點， 運用software去解決

"其實以前Fujifilm都好似有 sensor 分高低感光以拍出更大 Dynamic Range"
==> Fujifilm Super CCD ??

好似係Fujifilm Super CCD，不過好似無左了，生命週期太短了。
不過佢既design的確有點心思。

其實以今時今日相機像素，以四個pixel為一組，拍一張相時，那四個pixel分別有不同曝光時間，由processor 分析邊個曝光最合適，原理等同HDR不過一張相過免了鬼影，理論上應有好高dynamic range及足夠resolution呀

即如果拍1/100s相，
pixel A 1/100s,
pixel B 1/200s,
pixel C 1/400s,
pixel D 1/800s
甚至
pixel A 1/100s,
pixel B 1/400s,
pixel C 1/800s,
pixel D 1/1600s
當然講緊粒pixel的接收信息時間啦

以Nikon 36MP計，影完都仲有 9MP

It's something already available in Sony A99 (1 year ago) via DRO function ..... better ask Canon to focus improving the DR of coming sensors.

9MP 影片？勁過1DC喎
運算力要將36mp變成9mp, 看來粒U頂唔順
