加亮後:http://imagesl.fotop.net/albums2/no1yugioh/no1yugioh/0_182.jpg

相中左下角的後面,有一角色對眼的瞳孔離奇縮細,而且對眼變得很圓,好像向外突出,外貌非常恐怖,有像靈体的外表...

希望有專業人士解答

小弟用400D加sigma18-200mm鏡影的

I guess the Background person is "out focus"
F5.6 and 144mm 景深 may not enough.

好勁,靈異相都影到
下次避開就得,如果一定要加光又唔想咁靈異,blur 後面個人去

眼鏡反光加上失焦的結果。不用大驚小怪。

re: kentlho
"out focus"會有咁既透視效果??左下角個人對視被透視...四白眼...

re:Excalibur0991
左下角個人冇戴眼鏡架

此為左下角放大圖:

不如你搵返同一地點，同一角度，同一距離，同一焦距，同埋圖中二人再拍一次，睇下效果係咪一樣？

re:pongyee
冇可能再做多次同一條件既環境=.=
個人認為地點,角度,距離,同焦距都唔關事,我覺得比較有可能係部相機個ccd突然發生問題,或者係相中左下角那人,當時好短時間本身出現問題...因為當時影左好多相,只係依張有問題

[kentlho]

I don't agree 相中左下角那人,當時好短時間本身出現問題.Coz 1/100sec.
CCD突然發生問題?? That was a big area of yourCCD.
I did took a picture similar to yours few yrs ago.
The people was wearing a contact lens.
So I didn't think about it deeply.
Maybe You make a test yourself
Place a nourmal object in front of your Cam.(Center person)
And put a semi-reflective object back .(Background person)
Try...
I would like to know the answer, too.
Sorry for my Eng.Not Good. Hope your understand.

Crystal reflect maybe會有咁既透視效果,對眼被透視...四白眼...
That is not a solid reflection.

[kentlho]

I double check your photo.
I guess you out of the "safty shutter speed".
1/100sec with 144mm

[no1yugioh]

左下角個人係咪戴contact lens我需要d時間去問

我想看看你張有同樣情況幅相,可否send給我看waiman01010@hotmail.com

如果只係你講既Crystal reflect可能唔係幾正確,因為我對當時果個人都影左唔少相,但未有出現上述問題 (只有此相個人係out of focus)

可能出現咁既問題需要不只一項的條件因素,可能係Crystal reflect+out of focus
但如果只係此兩個factor的話,應該有好多人有咁既情況,但似乎又唔係有咁多人

我不明白你所講個實點做,是否要用上個該contact len做??然後再做一個模型模擬眼球??

請問"safety shutter speed"是指什麼??快門speed都有關嗎???
1/100s with 144mm出問題??我不同focal length都試過,我當時快門速度係固定1/100s,都沒有問題
