In selecting our subject…there are two factors which it should be borne in mind are essential, and these are Expression and Composition - Alfred Horsley Hinton

...but record and recognition are not pictorial qualities.

…the strongest part of a picture is the sensation and the feeling which it creates, this being done through the agency of certain familiar objects more or less accurately depicted and represented with more or less completeness.
The MOTIVE, then, in all pictorial work is to convey some thought or idea or sensation by means of a chosen subject.

It must not be supposed that it is always necessary to present our landscapes with an attractive and well-defined arrangement of clouds; on the contrary, it will often happen that the effect of a scene is best emphasized by a mere grey tint representing a covered sky or even a blue, cloudless sky; but this is a very different thing to rendering it as a white blank.
