D200 & Sb800 Hss

Yes fully agree but that were the days of 60CT2 and Pentax AFT400. All head and hammer flash. Also not forgetting tungsten light :bsmilie: :bigeyes:

I don't discount the possibility of that, but it is technically quite demanding to achieve that. The reason is that flash output is through a capacitor, and hence it cannot have a constant discharge power but will tend to follow typical discharge curves of the cap. To maintain constant output will require a far higher power source and extra circuitry just to regulate it and will result in the flash max power being limited to below its actual maximum power capacity.

The current HSS implementations Canon/Nikon/Minolta all utilize the pulsed flash method for both film and digital as it should be the most efficient unless there is some other breakthrough.

Dennis, Chee Wai and Zerstorer,

As to newbie to DSLR, I enjoyed reading your comments and information on this topic. Thanks for sharing!

Cheers

I normally don't write in this forum but can't stand wrong information being dished out...

Be careful what you read on the net. Do a deeper search and you will find the truth :bsmilie:

Yeah I noticed, something wrong gets posted, whammo, all the walking dictionaries come alive :thumbsup:

Thanks, beginning to make sense.
Now why can't they design speedlight like the SB800 to have a full power longer flash duration say up to 1/800 (like in the old days) and therefore allow flash sync from 1/800 to 1/8000 without cutting down on distance using the pulse (or multiple flash) method.
This limitation make the HSS not much of a use.

I was confused in the beginning because I tested a D200 with the SB800 using HSS (not even my cam as I have not use HSS before) but was surprise that the distance covered was not governed by the aperture but also by the speed which is not logical in flash photography. Checked and it seems like all equipment are functioning corrrectly hence the question.

Now it seems to me that flash design had taken a step backwards and at the same time a step forward on functionality and also becomes more sophisticated.

For flashes that have duration down to 1/600 or 1/800, even when you can sync at 1/1000 and above, you have to treat it like ambient light, which means that the shutter speed will start to govern the exposure. So in normal circumstances it's not because that shutter speed is not important but it's the flash duration which is shorter than the shutter speed that determines the exposure time.

Thanks to all, I now have better understanding of the flash system and will probably know how to use it more effectively.

Huh like that also can :sticktong

Which one? :bsmilie: Time to buy D2X liao,

Your Idol say it's obsolete liao mah...

must buy D200 now... go BBB
