小弟新手一名, 想請教有關室內使用閃燈既技巧....

有時去到indoor既場合, 樓底有高有低既, 場有大有細,
其實幾時先會加個diffusor直打, 加bounce卡向上打,
有時就乜都唔加向後打再反返前面?

同埋一後加左difussor係咪應該加返0.3EV?

請指教!

depends on colour of wall, and distance of wall / ceiling,
the most basic is that use the wall as a big bounce card or reflector.

If no suitable wall to use as reflector, then diffuser or bounce card; in which, diffuser can most likely make the light wider, where the bounce card makes the light softer.

For calculation:
f-stop = flash GN ( GN at 35 / 50mm) / light path distance (not the distance from object to lens)

where, I usually set the zoom head to 35 / 50mm when using bounce lighting; please refer to your flash gun manual about the real GN output according to different zoom positions.

Thanks for providing me so much information.....

just a further question. if there is no suitable ceiling for me during shooting,
and I am supposed to add a bounce card on my flash, do I still adjust my flash to 90 degrees against the ceiling?

Also, when I get the flash, I was given a free bounce card and its size is similar to a ping-pong bat, actually inside the flash there is one and its size is about half of the octopus card, so which one should I use? and whats their difference?

thx
