本人使用w5，每次用閃燈都很難控制相片過光，
請問用閃燈影人或物件，點可以唔會將主體過份光亮。

有時同一距離拍攝兩張相，偶然發現其中一張會將光線控制很得宜，
時否相機會自動感應作出調教，咁又應該點運用該功能呢？

請各位賜教......

That depends. Every flash has its minimum and maximum power output. If the shooting distance is shorter than the minimum output can handle (GN = distance x aperture), the subject will be badly overexposed. Please note that GN is ISO dependence. For instance, if GN is 12 at ISO50, it will be 24 at ISO200. The workaround of this limitation is to cover the flash tube with something semi-transparent, could be tissue or white colour plastic. You might need to conduct some experiment before you got your optimal solution.

To sam1989：

有一些人認為是調教閃光燈的問題，著重在閃光燈的調教上，我發現那可能有問題的，因為重點不一定在閃光燈上，而是你使用那一種「測光模式」，如果選擇得不正確的話，閃光燈的光亮度可能就不是你想要的，例如相機因為測光模式的錯誤設定，以為拍攝主題太暗，閃光會自動調整得光一點，就會出現問題。
