DC 來說已經差好遠喇... 如果 8 秒的燈光是剛剛好, 10 秒可能好像火燭吧!!

會有 "拋光" 不過都視乎你的光圈setting .....

see what u want to take, the image is dark or not, the light ray distance, no definite answer...

I have a photo taken by 8 seconds "Xmas Lighting 2"
and 13 seconds "Xmas Lighting 3"
The latter one distance is very far away, I think it needs more time for exposure...

I may be wrong ga.... coz I am a new user too......heehee

"拋光" happens because the minute flare, which may not be detectable in normal use accumulates enough under long exposure to become a problem. It is a problem of lens design and usually insufficient coating.

Try to shoot away from a direct light source or use lens hood (if available) / an object to shade to lens from stray light.
