A:

Can I take passport photo by myself?

There are several very specific requirements¹ for passport photos. Who takes the photo is not included in the list of requirements.

What should I pay attention when I trim the photo?

You should pay attention to the requirements listed by the state department or other equivalent governmental authority for the country in which you wish to have the passport issued.
In the United states, the size of the photo must be 2 x 2 inches (51 x 51 mm). The head must be between 1 -1 3/8 inches (25 - 35 mm) from the bottom of the chin to the top of the head on the surface of the 2 x 2 inch (51 x 51 mm) photo.
