點解我影藍天既時候，
由中間到邊位成日會由藍變黑?

是不是又是 SONY CCD....

[A.T.]

第一張係olympus
第二張係canon

係咩CCD 就唔知，
不過平時影相一d 事都冇wor~

會唔會因為曝光錯誤呢?

會唔會因為曝光錯誤呢?

don't think so

since i know little about camera so i could be wrong

but i heard that this is because
鏡片邊位會厚一些，阻多左光所以暗左

tomorrow i post some of my pic let u cc

周邊失光??
但係APS-C 用FF鏡應該好小有wor..
乜機影嫁?

雖然唔係好明問題，但好有趣，
係唔係問影藍天時總會在越靠近上方的位置會越深色？
影左好多年相都係咁，從來都未諗過呢個問題，
好似影灰或白天的天色無咁覺，
會唔會同藍光波長有關呢？

anyway i think it is normal after some simple reading...
i find many of my photos got the same problem
but not all...
i guess it is not a matter about your camera anyway
don't worry :)

排除黑角問題,因地球係圓,加上近太陽一邊會淡藍色d,相反太陽對住果邊會深藍色D,所以就會有此現象!
