HSS support

[hamlet]

Do the d7100 and the d800 support hss? Can these two cameras shoot at 1/8000 and have a perfectly exposed subject with no curtain shadow?

Yes. Refer to your manual. All you need to do is set the camera's sync speed to either of the two values (1/250 or 1/320) that are marked Auto FP, and the camera will automatically utilize Nikon's Auto FP feature when the exposure requires it, and when the flash is compatible. All modern Nikon flashes should support the Auto FP, which is just Nikon's name for their continuous flash. Though Auto FP is not an actual hss, it has the same effect, but with reduced maximum output from the flash.

The SB-400 flash does not support Auto-FP
Neither apparently does the Nikon d3100 and d3200, d5100.

this thread is kinda redundant of the other one isn't it ?

Yes, if ...

1. if your flash also supports HSS. SB-400 does not, internal flash does not, but SB-600/SB-700/SB-800/SB-900 does.

2. Your flash is connected to the camera to allow CLS communication between them. Commander works, but a PC sync cord or almost all radio triggers do not.

3. 1/8000 will decimate your HSS flash intensity (six stops down from 1/125 second), which is already 80% down in HSS mode. You will need heroic wide aperture and short range to compensate for 1/8000 second.


If indoors (ambient light more dim), your speedlight can be much faster than the shutter speed, and HSS is the poorest idea then.

yes it really is.

hammy, WHY the need for HSS? That's a very important question you have yet to answer.

 

[hamlet]

It will be used for modeling and sports shots. There is a whole new world out there that hss will allow you to explore.

 

[Braineack]

HSS doesn't stop the motion, the shutter speed does; the flash just fills in shadows from the sun.

And by modeling, do you mean modeling outside in the bright sun?

Here's a strobist you might want to follow, here he stopped motion of a jumping kid at 1/160 in a bright noon desert sun: https://www.flickr.com/photos/mortonphotographic/4089612915/

and again here, shooting mountain bikers at 1/200: https://www.flickr.com/photos/mortonphotographic/2304176976/in/photostream/

Just uses lots of power, two speedlights in one softbox to overpower the sun.


but here is a great example of him shooting flashes at 1/2000: https://www.flickr.com/photos/mortonphotographic/7172607648/in/photostream/

you can see how much shadow her face/body would be in without the flash filling. He had to use four bare flashes, all at 1/2 power, to do this using HSS.

I'm assuming he only did it in this manner because he was shooting at f/2.8.

I did experiment once of a long shutter, and HSS active to get multiple shots of a ball dropping. Basically you catch the ball at multiple points of it falling. Worked good for swords too

that's actually kinda neat.

on the other send of the spectrum, stopping motion using a 1/41,600sec shutter speed: https://www.flickr.com/photos/don_h...8zX-3sJ9ew-7C3Aum-5KFHEb-989UKQ-5KEVw9-coewU3
