好過3d matrix 嗎?再加一級曝光是否+1EV?

如果影人為主
點測是比3D好



生活在他方

The 3D matrix will tend to balance the exposure between the subject and background, if the subject grightness is  lower than the background then you may get the face a bit darker, for negatives, this gives grainy look for ubder exposed part. The matrix (3D here is not much sense if you don't use flash) is a mode which gives you a handy metering when you are in a rush and not time to checking metering, their outcome may not suit you taste.

For portrait, the main concentration is on the subject face and clothe, then proper exposure on the face is important. Spot metering of the face and add 1 EV is a gerneral practice for taking girl portraiture, assumed that the girl face is lighter than middle grey about 2/3 EV, then the final result is +1/3EV and this gives a better look of the skin, smoother and whiter.

If the subject has a darker skin, then the compensation is not the same. Use a grey card to check exposure and then +1/3EV or use a handheld incident meter and +1/3EV as most pro do in this way.

Hope this help.

這樣的人和景一起的相,正常的情況下要用多少的光圈才可得到足夠的景深?是否太小的光圈不好?

按景深掣 (或稱曝光預觀掣) , 然後自己決定。
景深關乎 : 鏡頭焦距 , 光圈大小 和 拍攝距離 ; 紙上談兵 , 無可能答到你。

1. Meter the correct exposure of the background and then use fill-in flash.

2. Use backet-exposure to ensure you get the correct exposure.

>>>相片應會好清,但會否有反效果

You decide it yourself. Does it 清 when you do not want 清?

>>我係想人和景都好清好清,但聽聞太小光圈會有反效果,是嗎

Usually, the best overall optical quality of a lens is best at middle aperture, say F5.6, f8. Usally, 小光圈 will have a lower quality but it should not have a very serious 反效果. If you want sharper result, use a tripod.

wrong concept on PL filter give better blue sky.
if it is not blue, PL will just **darken** it to become dark rather than blue. if you need good blue sky, either shooting at blue sky with correct angle, or blue color more sensitive film like Fujichrome Velvia.

理論上是可以的, 當然要加KENKO/TAMRON, 但質素就未必理想. 以TAMRON/KENKO 2X的價錢, 加幾百元已經可以買TAMRON/SIGMA的70-200細ZOOM, 質素及光圈都比加2X為好, 好好考慮吧.
