why is FP intended for?why would i need my flash to sync with my cam for shutterspeeds above 1/250?
other than background being darker, and flash firing distance shorter, why would one use such settings?:dunno:
Say in very hot sunny day. You need shallow DoF. So you use Aperture f/2.8. Your shutter speed is 1/1000s with the lowest ASA. And you want to use your SB800 for fill in flash. Use SB800 in FP mode allow you to sync in 1/1000s.why is FP intended for?why would i need my flash to sync with my cam for shutterspeeds above 1/250?

If your shutter speed 1/1000s and you want to use flash, no choice you must use FP flash mode. Alternatively you can use reflector for fill in light.ok, so FP is for daylight fill use.
so instead of FP, assuming i shoot at f2.8 and shutter of 1/1000,
can i switch the flash to manual for 'fill flash'?
i can just try and reduce the flash power output accordingly.can?

Why not organise a shoot and share experience...great.now i'm totally confused about fill flash in daylights and flash FP values.
so help me out guys.
1)if i want to use fill flash in such a way the it's like the flash wasnt fired, can i use flash FP?
2)is it even necessary to set my flash to flash FP for portraiture?:dunno: :dunno: :dunno: :dunno:

No. The standard flash duration is variable form about 1/800s to 1/30.000s (number is not correct as each model is different). Flash in M mode for M/1 will be around 1/800s (depend on flash model). Flash in M mode for M/128 is around 1/30.000s (again, depends on flash model). Flash duration in TTL or AA or A mode depend on feedback received by flash....However with high speed sync flash, the burst of flash is designed to stay on for the duration of its sync speed eg. 1/2000 sec (a standard flash lasts only about 1/30,000 sec).
