我用nikon d50, 50mm/1.8f
我之前在室內用了機身的閃光燈,影室內照時,可說滿意,
但是我擔心,時常用閃光燈,對BB的眼睛不好,所以我買了支50mm/1.8f,
希望用大光圈時,不用閃光燈,
但是我發現仍有以下的問題
1.沒有用閃光燈,相片好像不夠sharp
2.因家用黃光燈泡,拍出來時WB很怪(我用raw(nef),請問如何執好d相)
3.用了M mode或 A mode後,focus好像不清
4,用了1.8f後,BB不太清,是否影深太大
5.如果真的要加配件,如外置閃光燈,是否有d好似d膠/套,使光線柔和
6.可否介紹一下那支閃光燈適合我用,價錢大約多少?
謝謝!

影BB真的不要用閃光燈,原因一時間o既閃光,會令BB帶來驚嚇,最好開晒屋內所有燈黎影,如果開晒都唔夠光,咁就要買支強力射燈射上天花,令整間屋都柔和地光猛,咁!你用咩鏡,收一兩級光圈都影得靚了!

thanks,
i use the nikon 50mm/1.8f
收一兩級光圈即是用..2f/2.2f/2.8f/3.5f嗎?

室內唔用閃光燈相片好像不夠sharp，可能係你手震，你留意快門係幾多!

[joe123831]

快門大約是1/30至1/60

[joe123831]

我看了一些網頁,請問用跳燈技巧,射上天花..真的有用嗎?
請指教

[呀超]

更係有用啦，效果好靚添。

收一級 = 2

兩級 = 2.8

三級 = 4

四級 = 5.6

多謝 超哥..指教
那收一級...或兩級..
即2/f時..快門的建議是什麼(室內)
如2.8/f 時..快門的建議是什麼(室內)
請再指教..

超哥..你的作品很美

safe shutter speed >= 1 / effective focal length
= 1 / (50 * 1.6)
= 1 / 80 sec

1 / 100 sec would be enough

thanks..
我又學多左一d知識

各位師父..你們的作品..我不知要學幾久才有成績

那在室內..set WB時..最好用什麼呢..
用auto可以嗎?

1) Auto WB is very bad in indoor environment. Use Custom WB with a piece of white paper ; this will give you very accurate WB. For operation, pls refer to your instruction book.

2) If you like a sharper image for portrait, I suggest you to use f/2.8 or smaller aperture (such as f/3.2, 3.5, 4.0.....etc) with your 50mm lens. The sharpness of DSLR lens is very sensitive to the aperture you use. The larger the aperture, the less sharp it will be.

3) I always agree to using safe shutter speed to take picture. However, it will be very difficult for you to achieve 1/80 sec (safe shutter speed) in indoor environment. One simple way to solve the handshaking problem is to use tripod. By this means, you don't need to have strong light, you don't need to use high ISO, and you don't need to use very large aperture.

4) As a conclusion, I suggest you to use ISO400, use aperture priority mode (光圈先決)with f/2.8 as the aperture, use "center-weight" or "spot" as the metering mode, use Custom WB, plus tripod, this will give you satisfactory picture. If you still have problem, you may PM me to discuss.
