Object complements vs. predicate adverbs

The third kind of direct object sentence to look out for follows this pattern: subject + verb + direct object + adverb.

Muaz (subj) composes (verb) his photography (dir obj) beautifully (adverb).
Muaz (subj) develops (verb) his photography (dir obj) [in a darkroom] (adverb phrase).

These sentences are still about Muaz and his photography, but the presence of an adverb or adverb phrase in the predicate (beautifully), in a darkroom — tells us that now we’re talking about how and where Muaz carries out the actions that go into the creation of his photography, rather than how he defines it.

Adverbs modify verbs (beautifully — modifies –> composes)

object complements describe or name direct objects. (‘in a dark room’ — describe –> photography)
