The day turned out to be both sunny and clear!     For exposing white birds under this condition one can use the Sunny 16 rules and dail in an exposure compensation of -1/3 EV as in this case. Alternatively, you can meter off an area of mid-tone using in-camera reflective meter. Take a test shot and check exposure using histogram. I tend to expose white for 1/3 less since any blown white won't be recoverable even in RAW! Remember the rules would work best when the subject is mid-tone and front lit; two hours after sunrise and two before suset.     Hope this sharing of experience would help others!     EOS-1D Mk II, EF400/5.6L   Evaluative @ -1/3 EV, ISO 200, 1/2000s, f/5.6   KK Hui FRPS www.geocities.com/kkhui_001   « Last Edit: Jul 25th, 2006, 9:33pm by Tern Group » Logged Forrest FONG BBS Administrator I love Bird Watching!     Gender: Posts: 1123 Re: Black-naped Tern Inflight - II « Reply #1 on: Jul 25th, 2006, 8:50pm » Quote Modify Hi KK,   Thanks a lot for your valuable sharing.   Cheers,   Forrest   Logged FF Pages: 1  Reply Send Topic Print Forum Jump: ----------------------------- Announcement 簡訊通告 -----------------------------  - Membership Affair 會員事務   - Outings / Activities 戶外活動 / 講座   - Projects 項目計劃   - Crested Bulbul Club 紅耳鵯俱樂部 ----------------------------- Discussion Area 討論區 -----------------------------  - General 一般問題   - Conservation 自然保育   - Bird Identification 鳥類辨識   - Birding Reports & Tips 觀鳥報告及心得   - Photo Gallery 相片分享 I   - Photo Gallery 相片分享 II ----------------------------- Special Topics 特別主題 -----------------------------  - Wild Birds & Avian Flu 野鳥與禽流感   - Sustainable Management Scheme in Long Valley 塱原可持續生態管理計劃   - Black-faced Spoonbill 黑臉琵鷺   - Goodbye Penfold 告別彭福 => Tern Conservation 燕鷗保育   - Black-eared Kite 鳶(麻鷹)   - Swifts and Swallows 燕與雨燕   - China Birdwatching Network 中國觀鳥活動網絡   - Winter Altas Survey 冬季鳥類普查   - Nature Conservation Policy 自然保育政策 ----------------------------- Knowledge Sharing 知識分享 -----------------------------  - FAQ 常見問題   - Archive 資料重溫 « Previous topic | Next topic »
