I call my iPhone pictures 'photo sketches' because they tend to be grabbed on the go and perhaps have more of a snapshot spontaneity than some of my commercial work, which is usually led by an art director's brief. The photo sketches are processed on board the phone itself rather than on the computer and seldom take more than a minute or two to produce using a variety of iPhone apps. I hope they lend themselves to this notebook, which has plenty of blank pages for those occasional sparks of inspiration that can be so quickly forgotten unless scribbled down for posterity!
