Russian Verbal Adverbs: Aspect and Same-Subject Rule
A verbal adverb (деепричастие) adds a secondary action to a main verb: “while doing” or “having done.” Before choosing a form, make sure both actions have the same doer. In everyday speech, an ordinary clause may be clearer.

Imperfective: actions unfolding together
An imperfective verbal adverb commonly shows an action in progress alongside the main action: читать → читая, говорить → говоря. It often corresponds to “while reading” or “while speaking.”
Compare читая книгу, она пьёт чай (she reads as she drinks) with прочитав книгу, она пьёт чай (she has finished reading first). The form expresses the relationship between the actions, not a standalone tense.
Читая книгу, она делает заметки.
While reading a book, she takes notes.
Он шёл, разговаривая по телефону.
He walked while talking on the phone.

Practise simultaneous actionsPerfective: a completed earlier step
A perfective verbal adverb often presents the secondary action as completed before the main one: прочитать → прочитав, написать → написав. In many regular forms the ending is -в, but formation varies and should be checked for unfamiliar verbs.
Compare открыв дверь, он вошёл (he opened the door first) with открывая дверь, он услышал голос (he heard the voice during the opening). Aspect changes the sequence you convey.
Прочитав письмо, она улыбнулась.
After reading the letter, she smiled.
Открывая дверь, она услышала шум.
As she was opening the door, she heard a noise.

Contrast completed and simultaneous actionsThe same person must do both actions
In the ordinary construction, the unexpressed doer of the verbal adverb must be the subject of the main clause. Читая письмо, Анна улыбнулась works: Anna reads and smiles.
A dangling construction such as Читая письмо, у Анны зазвонил телефон incorrectly makes телефон the grammatical subject of the main clause. Repair it with a finite clause: Когда Анна читала письмо, у неё зазвонил телефон.
Читая письмо, Анна улыбнулась.
While reading the letter, Anna smiled.
Anna does both actions.
Когда Анна читала письмо, у неё зазвонил телефон.
While Anna was reading the letter, her phone rang.
A finite clause allows two different subjects.

Check subject and aspectSet off the verbal-adverb phrase
As a basic writing rule, set off a verbal adverb and its dependents with commas whether the phrase opens, interrupts, or ends the clause: Прочитав письмо, он ответил; Он ответил, прочитав письмо.
Some lexicalized expressions and close adverbial uses follow special punctuation rules, so do not treat this as an exception-free rule. For ordinary action phrases in a learner's sentence, the comma is the safe starting point.
Она, улыбаясь, открыла дверь.
Smiling, she opened the door.
Он вышел, закрыв окно.
He left after closing the window.

Read verbal-adverb phrasesWhen a full clause works better
A когда-clause can express sequence or overlap with explicit subjects: Когда она закончила работу, он позвонил. The verbal-adverb version would wrongly imply the caller finished her work if он is the main-clause subject.
Even with one subject, finite verbs may sound more natural in conversation: Она закончила работу и позвонила. Choose a verbal adverb mainly when its compact relation between two actions is useful and the shared subject is clear.
Когда она закончила работу, он позвонил.
When she finished work, he called.
Different subjects: она and он.
Закончив работу, она позвонила.
Having finished work, she called.
The same person finished and called.
