Rear shutter curtain sync
| Глоссарий по фотографии |
By default most cameras are set to front curtain sync which means that if the flash fires, it does so at the beginning of the exposure time. by setting to rear shutter curtain sync it fires the flash at the end of the exposure time. the difference in some cases me be negligible, but in shooting a moving subject front sync will put any motion blur in front of the subject, where as rear sync will place the blur behind the subject. neither is wrong, just preference.

Subtractive lighting, английский
As the name implies it is the taking away of light to create a desired affect. commonly it involves holding a reflector or opaque panel over the subject’s head to block light from above and open up deep eye shadows cause by overhead lighting. it can also mean holding a black reflector opposite your main light to create a deeper shadow, in essence reflecting black onto the subject instead of light.
