Why do you think wedding photos are fake when you look at them?

The retouching skills in the later stage were poor and the retouching was done too much.

Most photo studios do not have specialized post-processing and all are outsourced. These people need to edit N pictures a day, and they will do it one by one in such detail. Responsible ones are fine, but irresponsible beautification procedures will be done without even looking at them carefully.
