Translation:Let's take a picture.
what do i translate 찍다 too? I don't really understand how to use the word in another sentence
Is the ~을 really required in a short sentence like this? Because in a korean song the singer says "사진 찍어시퍼". Is it okay to leave something like that out?
in short sentences like this where the object of the sentence is obvious, yes you can leave out the ~을 :)
