Whether for photographers or photography enthusiasts, they will always be disturbed by an endless stream of tourists when capturing landmarks, squares and urban landscapes. Recall that how many times you had to wait patiently in front of some tourist attractions, just in order to take a satisfactory picture without being disturbed by the tourists. If we don't have that much time to wait, didn't wait for that opportunity, or all you have in hands are some photos you had taken at random, then you can still easily remove all the unwanted objects in these photos with the help of some software.
