Abstract
THE Watkins exposure meter is known wherever photography is practised, and the many other instruments that Mr. Watkins has introduced to render photography less haphazard than it so often is enjoy a wide appreciation. The author therefore comes t6 the task of writing a general treatise with what we may perhaps call a praiseworthy prejudice. Of this he is doubtless aware, for he says in his preface: “The greater attention given to my own methods in exposure and development will, I am sure, be forgiven.” The author makes these methods clear and illustrates them well, and proves the error of certain notions that have been put forward from time to time, as, for example, that one should regulate the exposure of the plate according to the light that comes from the object rather than that which falls upon it.
