Well, not necessarily. It depends of many parameters such as:
- The exposure time
- If the woman in pink was moving just before the shoot and, if so....
- In such a way that only it's face and neck was affected and...
- How much time there was (during the whole exposure) between its move, the opening of the shutter and the position were she was standing at
how much time there was between the position she was standing at and the moment of the closing shutter.
- The contrast between the various elements of the scene (the background, ...)
As an example is always worth a thousand words, let's take a look at this photo (that I worked on two years ago)...
...that is not showing any ghost, but only a short exposure (probably one-tenth or so of sec.) of the girl on the right that moved to the right during
a very few part of the whole 2s exposure, giving this ghostly aspect.
As you can see, there's no blurry on the "real" girl face on the right, as the exposure is almost complete, and there's no white color report of the
However, you can see in this example that even the girl on the left moved during the exposure as we can see some duplication of its right arm ("2" in
the image below)
"1" is to show the effect of a long exposure on a screen (TV, computer...) that appears then to be over-saturated.
