Can anyone tell me how the data helps determine what the image is?

How is the data helping to tell if this is a UFO or not?
Hi Dave.
For an image like that one, the EXIF data tells us a few things that may be useful (let's ignore the question of how to verify that the exif is
real..).. First up, as already noted, it shows the image has been edited/saved in Photoshop, so it isn't the original. Second, it shows the shutter
speed as 1/4 second, which is *way* below hand-holding speed. That tells me that unless the camera was extremely securely mounted, the image will
contain motion blur or motion artefacts. Any blurring or double image effects (which do appear in this case) are likely to be entirely or partly
because of that - in other words, they do not necessarily indicate object movement.
The exif also gives the brand and model of camera - from that we can work out lens capability (the exif also shows the focal length that was used),
sensor size, even sensor efficiency - whether the camera is good in low light, etc.. It will also tell us if flash was used, whether exposure
compensation was used to darken or lighten the image, what type of exposure metering (eg spot or averaged), what color balancing was in use - and all
of these things *may* be helpful.
Other than that, there isn't much of interest in the exif for that image...
In regard to the image itself, given the high noise levels, I'd definitely want to see the original (and as I happen to know that the S5000 can do
this, I don't suppose you have a 'raw' version of it?). Nice lil' camera by the way - I used to own one of its bigger brothers.
As for the OP image - there is absolutely nothing in that, of interest.
