請教大家兩個有關數碼黑白攝影的問題.
1. 用RAW出黑白跟用黑白JPEG Mode出來的效果分別大嗎?
2. 以前用開的黑白Filters, 例如紅黃橙藍等Filters還有利用價值嗎?
2. Post-processing is an essential component of digital photography.
No need to use B&W filters anymore udring shooting,
or you loss the benefits/potentialities of digital photography.
If you understand the basic principle of B&W filter well,
then you have a good position to start with.
For example, if you want the effect of yellow or orange filter,
you simply use channel-mixer, the portion of R is set to 40%,
G is set to 40% and B is set to 20% (total is always 100%).
[remember the effect of yellow filter is cut off a small portion of blue light?] Try to play with different portion and find out what you want.
Basically, for Terry Dada (always have beautiful models), the rule of thumb is set R (primarily) higher in % and B in lower %, you get flattering (white radiance) skin tone.
Hope these help.
