如果有三間房，形成品字形。 第一間房開着光管，第二間開着烏絲燈胆﹝60W﹞。 相機在第三間房無光兼全黑，向着兩間房平均地影埋去。 結果係：

白平衡如果set 光管，咁張相就第一間房色温就正確；第二間就錯咗色温。
白平衡如果set 烏絲燈胆，咁張相就第二間房色温就正確；第一間就錯咗色温。
白平衡如果set AWB，咁張相就兩間房都有少少錯色温。 唔係無，但好微。

請問各位師兄，應該點攪先至啱呢﹖ 可以同時影到兩間房嘅正確色温。

多謝回應！

Good question
I face the same problem in some church before during wedding photo taking.

The stage is tungsten light, the pride is perfect lit. In the same frame, the background church is lit by fluorescent light which end up give the audience a greenish face.........
I end up avoid taking both object in same frame.

But if it is unavoidable, and a correct colour is needed, then I will take RAW and convert them into two jpeg with white balance set to tungsten and fluorescent and combine them in photoshop with gradient layer

多謝h0001244 師兄回應。

你個情況，其實可唔可以用閃燈Full Power 強閃對像物，等閃燈嘅白光替你張相修正所有objects 嘅色温呢﹖

閃燈Full Power 強閃對像物 would lose the beauty of ambient light .......
I prefer a church of soft and warmth lighting..........romantic mood

ps. some typo in my previous reply ~ it should be graduate filter layer
