Sufficient acknowledgment
In relation to certain exceptions, if you are making use of that exception to copy someone else's work it is necessary for you to sufficiently acknowledge their work. For example, where you have copied all or a sub-part of a work for the purposes of criticism and review or where the use was for the purposes of news reporting.
However acknowledgment is not required when used for reporting of current events by means of sound recording, film, broadcast or cable programme if it is impractical to include such an acknowledgement.
Note also, the exception relating to news reporting does not apply to the use of photographs.
