What has happened here ? [ photo ]
I was taking pictures this afternoon of my kids playing with their toy cars [ the ones in which crash and the doors fly open etc etc ] - anyhoo, whilst snapping away and playing with the shutter speed, this one caught my eye and I am still trying to work out what has happened.
The car was setup to go off sideways off the ramp which you can see it has but for some reason the car detail is very transparent - more of a ghost car. Anyone got any explanations ?
Details on the picture is as follows:
1/2 sec shutter

Because of the red blur further to the right of the image it looks like a double exposure, the first is a short one taking the car and the second taking a long one taking in the blurred car.
Something gone a bit strange with your settings?

Could it be that because your shutter speed was slow (1/2 second is quite slow).
The camera was able to take in the bridge before the car came into shot... hence it's included the detail behind the car, making it appear transparent.
Also did you use a tripod? remaining that steady for 1/2 second is impressive!
p.s 1,000th post!

So... it's not a ghost car?

I'll go with the double exposure I think.
Not on a tripod. The other ones I took were these:
Different settings etc.

Forget the picture - how tidy is your house? Remarkably tidy for a house with two small children
Also housework question- is that a solid wood floor? If so what do you use to clean it, we had solid flooring put down recently and am stumped what to use to clean it?

Well this photo mimicks exactly what happened and was taken using a slow shutter setting - File:Shutter speed pool.jpg - Wikipedia, the free encyclopedia

Well thats interesting as when I was taking the shots I lowered the shutter speed to try and get the feel of visual movement..... I only took that one as the missus then arrived home and we had to put all our toys away.......

First one without flash, other three with flash?

All with the flash - was trying not to use it to start with but with a fast shutter speed I was getting just very dark images - even using a high ISO & open aperture. Ended up turning all the lights on and using the flash.....

What is you maximum Aperture? f2.8? 3.5?
For indoor without a flash you really need something like a 1.4 or 1.8 and even then you will need to crank up the ISO to avoid any motion blur.
If you wanted the look of visual momvement then panning would have done the trick with no flash and a slow shutter speed.

What you've done is usually called Slow Sync Flash. By setting a long exposure for the background ambient light and using flash for the foreground detail you end up effectively with two exposures on the same frame.

The flash is the key - the flash would only have fired for a fraction of that half second exposure, so the ghost car is just where it was when the flash fired. Without the flash you wouldn't have got it at all, it would just be a blur over half a second.

Does your camera have any specialist flash modes, such as 2nd Curtain Sync Flash (sometimes known as Slow Sync Flash)? Using a conventional flash setup at low shutter speeds the flash normally fires as the shutter opens but with more sophisticated features it is possible to have a 'pre-flash' as the shutter opens, followed by the main 'flash' just before the shutter closes.
It looks to me as if there may have been a pre-flash (anti-red eye?) which captured the car followed by a main flash which exposed the rest of the image.... but I am not an expert on these things
