小弟近日影了幾張藍天的相, 發覺相的左上角有二至三点淺灰点. 請問怎樣才知到是ccd 有塵還是鏡頭有塵呢?(本人有加 B+W Filter)
請指教!

要影到鏡頭內的塵，近乎冇可能。
我覺得會係CCD有塵，找風泵吹吹佢。
如果冇改善的，上行清都得。

或者係filter 外面有塵
吹下filter/ ccd, or 當睇佢唔到

agree with cosplay

[老叟]

想確定CCD有塵咪影一張全黑,一張全白咪知囉

[Ah Chai]

可以影一張全白，收細光圈影，就會見到哂d塵。

至於「一張全黑」???
老叟兄
點解要影全黑???

小弟有次有只蚊子飛到UV上面，結果拍出來幾幅照片都有黑點。
真“難爲”他不飛走，最後更給他咬了一淡

有冇c兄係can0n用家
拎上去cs清, 大概要幾多日先攪掂?
效果又如何呢?

So simply, if change to another lens and dust still at same position, then not relate to lens.

very simple

photo a white paper in a indoor enviroment with add +1ev no flash menu focus

than take the picture on the photoshop and slow add the contract than you can see many many dust appear


you can buy sencer swab and sencer ligud only clear two time by you seft is ok

nearly 98% dust will off
