Add / Remove People In A Photo: The Stacking Method
Who has not one day pestered against all these tourists not stopping to parade in front of you and preventing you from taking your picture without people on it? Well, all this is passed. Thanks to the digital and the stacking method, you do not need to have the most sophisticated photo editing software to succeed in this magic trick ...
As we will see, erasing
people on a photo is relatively simple and fast. The only things you need to
know in order to do this trick are the eraser tool and the layer management
principle. I also specify that if we can delete people with this method, we can
also proceed to the opposite phenomenon, namely to add. This is also what I did
on the example below or everyone is walking on one side of the street.
The principle
How is it possible?
Simply because by taking the same photo several times in one place, people
move. If on the first picture a person is on the right, it may be a little more
to the left on the next picture to see outright out of the field. By
multiplying the views, we will be able to superimpose them. Deleting a person
will return to the erase on the layer where it is present.

Equipment
For the realization of
this kind of photo is possible, it is imperative:
A digital camera that
can be disengaged in manual mode and on which you can disable auto focus (I
explain the reasons in the next chapter).
A tripod or failing, a
stable place or put the device.
The shooting
I specify, before
presenting you the method, that it is necessary that the conditions of lights
are the most stable possible (no photos at sunrise - sunset, or with clearings
- without clearing). Indeed, if the amount of light varies, you will have
lighter or darker areas where you have deleted people. It will always be
possible to rectify the exposure of the photos once in front of his computer
but this complicates and lengthens the work. So privilege this kind of photo
for example by the bright sun and in the middle of the afternoon. That is said.
To take your photos,
follow these steps:
Mount your camera on
your tripod and determine your frame.
Focus at the desired
position and then disengage the auto focus (M position on the lens).
Choose ISO sensitivity
and set your camera to the manual position (M mode). Determine speed and
aperture settings to have a well-exposed photo.
Take the first picture.
Locate the people's
position and take a second picture when several of them have moved.
Make it so many to be
sure to have on at least one photo an area not covered by a person.
The photo montage
Open all photos and position
them as a layer in one document. Tips and tricks: if you have moved slightly
between 2 shots and you have Photoshop Elements, use the Panorama Photo merge function (in the "Settings" menu). Your photos will be superimposed
automatically. Be sure in this case to remove the merge masks that will appear
to the right of your photos.
Hide the top layer (the
eye on the left) and look at the people who appear/disappear from the image.
You now know which person (s) you can delete in your photo. The layer with the
person to delete must be above the one where there is no one.
Now lower the opacity of
the layer above. This will allow you to see the area to reveal (what's on the
layer just below).
Lower opacity is very
interesting because we see better or pass the eraser (especially in the case
where we want to add a person)
Take the eraser tool.
Adjust the size and choose a blurred edge. Pass on the person (s) to delete.
She disappears as if by magic ...
Now merge the top layer
with the layer below.
Go back to step 2 and do
this until you have processed all the layers in your image.
And now, there is no
longer a cat or so, it is swarming with people if you have opted for the
opposite solution: clear areas where there is no one to make appear people on
the layers below.
Conclusion
It is obvious that this
method only works if people move. If some people are napping or reading, they
will have to be at least as patient as they are.
The number of people in
the photo is also crucial. Do not expect to empty a street if the photos were
taken during a demonstration.
