相機LCD顯示顏色真的準確嗎?

Kenrockwell 關於相機LCD顏色準確度的文章以色溫 ( K ) , Delta uv , 亮度(fL)來測量現有若干像機機背的LCD顯示照片是否與實際相片顏色相符, 其中以Canon, Nikon的DSLR, DC來測試, 發現Canon 30D居然比20D的色偏還多, Nikon D80也優於D200, 更遠遠優於D70, 映證了多數人的使用經驗!! 該文有詳細測試結果分析, 尤其注意Delta uv的數值!!

Delta uv is the important number. This is the inaccuracy of the the white point. This is how far it varies from pure white. Like golf, the lower the score, the better the accuracy. Anything better (less) than 0.03 is spectacular, and anything around 0.50 is pretty bad. Delta uv, the error, measures shifts in green and magenta.
