想問下個月去韓國, 帶埋部450D去影雪,有咩要注意, 點樣保養部機呢? (因為室外零下幾度, 室內有暖氣, 驚整到部機有霞氣...)
另外聽人講影雪景唔同一般影景的, 有咩技巧呢?
請幫忙

入到暖o既地方,唔好立即拎機出黎,否則霞氣無可避免.

係雪地,拍攝時通常都要加ev.

no problem at all ga.... low temp normally is low humdity so you should be safe in USA, BUT the lense get fogged then is due to the rapid temperature change . To avoid this:

1.) Put it in a carrying bag/back pack when in not in use or before walking in to different environment
2.) open the zipper/ cover of the carrying bag allowing air exhange for several minutes
3.) ready to use


Also snow should be -EV but you may experience color loss due to reflected light from the snow. (also watch for snow blind, wear sun glasses if needed)

視乎測光模式...但以全幅測光計，大部分相機會被雪地騙到而嘗試把雪地轉做灰色

小弟覺得，若要還原現場感覺則需要+ev:
雪天雪地佔構圖多少加多少，佔1/3 +1/3，佔2/3 +2/3...
若有籃天少雲，籃天佔構圖多少減多少
有人再加1/3

差不多是這樣了...

your +EV only applies to when there is not enough sun light. Snow is highly reflective, I have tried +EV before 1/3 step then the image is appering white colors.
