A method for differential photometry of
speckle-interferometric binary and multiple stars is presented.
Both the accuracy and sources of systematic errors
of the method are analysed.
The photometric accuracy ranges between 002 and 0
20,
depending on the atmospheric seeing, the brightness and the
separation of the system components.
A comparison between our magnitude differences and those
of other authors is presented.
