Would you share with me your view. Many thanks. Regards Daniel P.S. I wanted to use manual exposure but you knew it was not easy on the boat with an EF500 on hand. « Last Edit: May 25th, 2004, 5:07pm by BBS Moderators » Logged Daniel CK Chan http://www.danielckchan.com 648 BBS Member BBS God     Posts: 439 Re: Black-naped Terns 黑枕燕鷗 « Reply #1 on: Aug 15th, 2003, 8:54am » Quote Modify Daniel, 美極了！ 可惜右下方的鳥分散了不少注意！ 飛 Logged KK Hui BBS Member BBS God Bird Photography - at its best ...     Posts: 940 Re: Black-naped Terns 黑枕燕鷗 « Reply #2 on: Aug 15th, 2003, 8:58am » Quote Modify I agree that the exposure could have been better ... A nice shot nevertheless, Daniel!   With digi cam like the 10D and for white bird, I'd compensate for -1 1/2 at least in this case; it's always better to under expose for retaining plumage details. Shooting with RAW and you have nothing to loose!     Shooting M mode with incident light meter you may be more in control over exposure especially when the BG is ever changing but still you need to compensate for anything white.     BTW, the image was a tad oversharpened noting the halo around the edges ...     Best kk -------------- www.geocities.com/kkhui_001 Logged Daniel CK Chan BBS Member BBS God I love nature photography!     Gender: Posts: 794 Re: Black-naped Terns 黑枕燕鷗 « Reply #3 on: Aug 15th, 2003, 10:42pm » Quote Modify on Aug 15th, 2003, 8:58am, KK Hui wrote: I agree that the exposure could have been better ...

However,  some of the other photos taken in same day are good in exposure (with -2/3 Av evaluative) such as the portrait of Roseate Tern 粉紅燕鷗. This one however is in backlight situation so the over-exposure should be so serious?! Anyway, the exposure of 10D made me frustrated! « Last Edit: Aug 15th, 2003, 10:58pm by Daniel CK Chan » Logged Daniel CK Chan http://www.danielckchan.com KK Hui BBS Member BBS God Bird Photography - at its best ...     Posts: 940 Re: Black-naped Terns 黑枕燕鷗 « Reply #4 on: Aug 16th, 2003, 8:32am » Quote Modify on Aug 15th, 2003, 10:42pm, Daniel CK Chan wrote:   ... some of the other photos taken in same day are good in exposure (with -2/3 Av evaluative) such as the portrait of Roseate Tern 粉紅燕鷗.

Anyway, the exposure of 10D made me frustrated!   Daniel,   It's the backlit intense reflection on the upper wings of the flying bird that was vastly over exposed. The two stationary birds on the lower left are reasonably well exposed however. This is what I'd come to expect as you only compensated for -2/3 in Evaluative metering. In all fairness, I'm not too surprised with the result and remember 10D digi cam makes it worst!   Best kk ------------- www.geocities.com/kkhui_001 « Last Edit: Aug 16th, 2003, 8:33am by KK Hui » Logged 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 »
