		<description>相機測光系統會認為測光點或測光面為中灰(或16度灰)作標準。

若畫面為高調(比較光如雪景)，測光時仍會以中灰為標準，
會給出一個較底的曝光值，影出來白雪變灰雪，所以要加EV。

若畫面為暗調(如夜景)，測光仍會給出中灰為標準的度數，
會給出一個較高的曝光值，影出來黑夜變陰天，所以要減EV。

所以當攝影前，以環境及畫面決定應加或減，便有＂光加暗減＂的口訣。

而不是影完後發現相片過光或過暗再加減EV再影。

而Ken Wan所講的點測光，
如善用的話(如尋找畫面中光度區或以主體測光) 加AE Lock，有時的確可以不用曝光補償！</description>

		<description>兩種講法應該是一致的

口決中的“遇光則＋EV”應該係指當對住一大片比較光的物件或環境(如雪地)進行測光時要＋EV　

而文中講到“太暗”係指當相機測光所得出的結果偏暗就應＋EV

以上是我的理解</description>

		<description>但是文中的例子是太暗加EV，與口訣遇暗則暗(-EV)，遇光則光(+EV)相反。可以解釋嗎？Thank you!</description>

		<description>To editor, here is some common confusion about EV and Exposure Compensation in EV

EV and Exposure Compensation in EV is 2 different things.

EV: Exposure Value
This value is constant and cannot be set in camera

Exposure Compensation in EV (&quot;EV&quot; button in camera)
When all of the values are present, this value is the adjustment on the final EV result, and this is the &quot;EV&quot; that can be set in camera.

		<description>我想問一下是不是如果用點測光就不會出現文中提及的誤判？</description>
