Slower Shutter Speed?
This is taken from an article I read about flash photography. The problem is a large room with a dark background even when a flash is used. You want the background to be brighter w\o blowing out the foreground subjects. His solution was to lower the shutter speed to 1\8th or even 1\4th @ f4. He goes on to say that the slow… -
Re: Slower Shutter Speed?
When shooting flash in manual mode ( camera and flash unit in manual ), the aperture of the camera and the flash distance to the subject determine the proper exposure for the subject. The shutter speed then limits ( sets) the exposure for the background ( unless the shutter speed is much faster than the flash which does… -

I think what he's saying that the area is so dark that when taken at as low as 1/4 of a second there wouldnt be enough light to expose the subject, that's where the flash comes in, the flash will brighten up the subject but only for the duration of the flash, that's how it stays sharp. I'm still not sure how he expects the… -

Flash Duration Duration of light output varies. It can be very short or up to say 1/200 of a second. The brighter the flash, then longer the output lasts, so if you want a very short flash duration, say short enough to freeze very rapid movement, then you need to set up the shot to allow for a smaller amount of flash… -
Re: Slower Shutter Speed?
The flash duration is much shorter than the shutter speed. Typical flash durations are 1/10000 second (this is how people stop motion on things like bullets) which considerably faster than the shutter. You can think of a shot taken with a flash as really two images overlayed in one picture: one taken with just the flash…
